Westmore 501 (Triplett 3444) Mutual Conductance Tube Tester - Calibrated 5/14
Selling this wonderful Westmore 501 tube tester(rebranded Triplett 3444) This is arguably the best tube tester(non-industrial) ever produced for the consumer market. I purchased this tester in May. And the seller on eBay told me it was completely refurbished, calibrated and verified. I received it, it is immaculate. I cannot either figure how to use it, or it is in need of further calibration. I cannot get the tester to move past about 1/4 of the meter. Perhaps something is loose from previous transit, or I don't know what I am doing(which can be the case) Please look at all the pictures. Including the image of the test/calibration results. I assume with VERY LITTLE service, you will have the ultimate tube testing machine- capable of testing TRUE Gm and Plate Current for premium matching. Instead of spending more time trying to figure ... morethis out. And/or sending it for a service/calibration, I am taking a LOSS on this item, and will be going back to my trusty 3423(the little brother of this beast) Free US Shipping. Sold as-is. In need of either service or a capable operator(I am not certain either way) I paid well over my asking price 2 months ago. The original seller will not help me with this- he has been selling these 3444/501's a few times over the last couple of years apparently, and others have had the same problem.

Hickok 533A Gold - Calibrated & Everything Within Specs Works Great Late Version
Hickok 533A Tube Tester Later Version that is Gold Anodized This later model has a calibration adjustment pot that can be seen in the pictures that is not on the earlier 533A testers. There are no resistor spools on this newer version 533A. But instead has precision resistors. I will provide a copy of an updated manual(unbound) and that includes calibration instructions and other important adjustment and information not included in the original manual, the schematic, and operating instructions. There is an abundance of available information including the manual, schematics, and tube data available at no charge at Bama and elsewhere for a Hickok 533A. Went through all the calibration steps and checked all the voltage specifications and they were all virtually perfect. Plate voltage. Bias voltages at 100, 75, 50, and 22, signal voltage, screen ... moreand low screen voltage, filament voltages and checked with 6l6 loaded, shorts test, and calibration tubes. The picture with the DMM is showing the line voltage for a 6L6 set at 6.3 volts, and with the 6L6 in the socket the line voltage reads 6.14 volts. The line voltage being correct is critical to obtain proper Gm test results. Many Hickok testers can still be calibrated, but with a tube in the socket the line voltage drops under 6 volts and you get low Gm test readings. Tested a 6L6(Gm is 5475) calibration tube that tests with almost the exact Gm, and a 6AX7 with that also tests close to exact Gm on both sections of the tube at 1440& 1400 Gm that are pictured. The meter is nice and not cluttered with unnecessary numbers making it easy to read the correct Gm or Good/Bad. This 533A also has the noise test which is something that anyone testing tubes for their amps may want to get used to using in order to weed out noisy tubes that test good. It is very easy and once you hear a noisy tube you will understand how the test works. It is almost all original. All the covers are there for the bulbs which is a plus, and the 83 and 5y3GT tubes are as good as new. The original two-

The face of the tester is in nice shape except it is missing the 9 pin straightener on the panel but I have included a 7& 9 pin straightener shown in the photos and the outer case is not perfect but nice compared to most I have seen with a few minor scuffs& wear but very solid. The operating instructions& tube data settings manual is also included with the instructions and settings for the 12AX7 full scale mod. So if you have any questions please feel free to ask and good luck. Froo www.froo.com ... more| Froo Cross Sell.

Hickok 800A Tube Tester Calibrated & Everything Within Specs NO Adapter Needed
Hickok 800A Calibrated& Everything Within Specs Includes 9& 12 pin Compactron Hickok 800A Tube Tester 1971 More Pictures Below Description This later 800A model has a calibration adjustment pot. That can be seen in the pictures, that is not on the earlier 800A testers. The CA-4 adapter is not needed since this can test all tubes up to 9 pin mini, and the 9 and 12 pin compactron. There is an abundance of available information including tube data available at no charge at Bama: Went through all the calibration steps and checked all the voltage specifications and they were all virtually perfect. Plate voltage. Bias voltages at 100, 75, 50, and 22, signal voltage, screen and low screen voltage, filament voltages and checked with 6L6 loaded, shorts test, and calibration tubes. The picture with the DMM is showing the tester set at the line, ... moreand a 6L6 in the socket and the filament/heater voltage reads 6.29 volts with the tube loaded. The line voltage being correct is critical to obtain proper Gm test results and so is the heater voltage. This later versions of the 800A has a calibration adjustment for the AC line test. Adjustable resistor R24/ 100K is used and is the the POT with the blue knob pictured. Many Hickok testers can still be calibrated. But with a tube in the socket the filament voltage drops under 6 volts and you get low Gm test readings. Tested a 6L6 calibration tube that tests with almost exact Gm at 5500 and the tube calls for a Gm of 5475. Tested a 6AX7 calibration tube that tests at 1400 and 1450 Gm and the tube calls for 1400 and 1440 Gm and are pictured. The 6ax7 is not on the roll chart and located in the obsolete tube data. It is all original including the two tubes. The 83 and 5y3gt that were tested on a Hickok 752. The 83 tests at 1050 in both sections and 600 is the min. The 5y3gt tests at 625 on both sections and 400 is the min. This tester has the original grounded plug original to the tester and the roll chart is dated 1971 and turns smoothly. This Hickok 800A is in exceptional condit

Hickok 800A Tube Tester - Calibrated - Plate Current Mod - EasyCal Mod
Nice refurbished Hickok 800A tester- Calibrated- Plate Current Mod- QuickCal Mod This is a very nice Hickok 800A tester. Case is in great condition with minimal wear and no large rips or damage. The tester has been modified to test Plate Current using the diode test points just under the meter. Instructions on how this works included. It is important to test idle current when matching power tubes. This tester is the newer vintage of the 800A with the voltage set pot(see blue dial in interior pictures) This tester has been refurbished so that the clunky adjustment rig R15 for bias and reduced screen voltage can be quickly and easily set. This modification worked so well Im installing it on all my testers now and may offer a kit for others soon. Never before have I been able to so quickly and easily calibrate a unit. Calibration results- Plate ... moreVoltage = 152.1 Screen Voltage = 132 Reduced Screen = 56.1 Bias-39.0 Bias@22 =-3.0 Leakage test= pass Filament 6.5(6.3) 12.5(12.6) AC Signal= 2.5V Very nice results for this field tester! A Noval and Octal socket saver have been added to ensure the most common tubes test well. A regulated Solid State 83 replacement has been included to ensure stability and long life of the tester. The roll chart turns well and is dated 4-1-66. But I have also included all documentation and test data(including some error fixes) that I have for this model on CD so you don't need to use the roll chart, and can preserve it. The leakage/shorts check dial in this unit feels like there are an extra indent between settings. I have checked out the control and electrically it is functioning as designed and is in good shape you just need to ensure you are looking at where the dial is pointing in particular with that control.

TV-7 D/U Hickok Tube Tester Calibrated Great Condition Good Working Order TV7
Hickok TV-7 D/U Military Tube Tester. I purchased this in March 2013 from C.G. Industries. C.G. Industries had calibrated the unit 12/28/2012. The unit has a small sticker above the meter with their contact information. I have used this tested to test hundreds of tubes I have sold to customers and it's done a great job and served me well. I have decided to sell this unit as I recently purchased a 539c. The tester is calibrated and in great working condition. It includes the original 7.8, and 9 pin socket savers, extra 9 pin and 8 pin adapters, one test lead, and two factory adapters that I honestly have never had to use.

Very Nice refurbished Hickok 800A tester- Calibrated- Plate Current Mod- QuickCal Mod This is a very nice Hickok 800A tester. Case is in great condition with minimal wear- please see photos- this unit is a rare find in this condition. I had two of these nice condition 800A testers and the other sold. So this is the last one. I have a couple of others I will be offering soon but no more that are quite nice considering the age of these vintage testers. Note- the 800A tester has the extra sockets to do the compactron tubes(without a separate adapter) It is also one of the few Hickoks that can measure tube leakage on the meter! The tester has been modified to test Plate Current using the diode test points just under the meter. On this unit a banana plug jack has been installed. So you will need to make or buy a set of banana leads for your DMM ... moreto use if you dont already have. Instructions on how this works included. It is important to test and match idle current when matching power tubes for class B or AB operation. You can test current on any tube. This tester is the newer vintage of the 800A with the voltage set pot(see blue dial in interior pictures) This tester has been upgraded so that the clunky adjustment rig R15 for bias and reduced screen voltage can be quickly and easily set.

EICO 667 Dynamic Conductance Tube & Transistor Tester Repaired Tested Calibrated
Here is a clean. Calibrated and tested EICO 667 Tube Tester. It works because I tested it and fixed what was broken. Testing revealed several problems including an intermittent tube socket which had to be replaced. The only thing I wasn't able to test was the 7 pin Nuvistor socket because I don't have any of those tubes. I checked the socket wiring and it looked OK, so that socket most likely works as it should. I checked the transistor test function with both PNP and NPN transistors. It worked just like new. Most people looking to buy a tube tester rarely consider the transistor function. But the EICO 667 has a pretty decent transistor tester built in. It checks both the Iceo(collector to emitter. Open base) leakage current and the Beta. This works especially well for signal transistors. The EICO 667 Dynamic Conductance Tester is ... morean excellent tube tester which provides much more reliable results than the typical emission tester. I have a weak EL34 tube in my parts box that tests good on almost all emission testers. This 667 correctly rejects this tube as bad. See picture. Overall this tester is in very good condition. It has minimal marks on the faceplate and meter lens. The switches and controls all work well and the tube sockets are nice and tight. The roll chart works well and the meter is smooth and repeatable. Take a look at the photos. They do a good job of describing the unit's overall condition. There are 10 sockets on this tester's panel and it can test many tubes that will fit in the sockets including 5& 7 pin Nuvistors. 7& 8 pin sub-miniatures, 7& 9 pin miniatures, 9+1(center) pin miniatures, Octals, Loctals, Compactrons, and some Novars(top-evacuated) The Novar socket is also used to test panel lamps. The included test charts list additional types that you can test with the appropriate adapter- namely antique 4, 5, 6& 7 pin large base, Decals and Magnovals. Yes. This tester will test most rock'n roll tubes and many ham transmitter tubes without an adapter. If there

CTI TC-20 Commercial Trades Institute Vacuum Tube Tester Calibrated Audio Ham TV
Up for sale is a later model emission tube tester that includes sockets and test data for Compactron. Novar and most other recent vacuum tubes. This tester can test many audio and transmitter(sweep) tubes. Comes complete with an assembly manual, schematic and two test data charts. Also included is an"as-built" schematic which is a little different from the one included in the assembly manual. The tester is in good to very good condition(see pictures) and works as designed. All sockets. Controls and transformer voltages have been tested, and the line setting has been calibrated. The CTI TC-20 is designed just like the Heathkit IT-17& IT-21 series of tube testers, and the test data charts are interchangeable between them. The TC-20 has the following sockets: Octal Loctal Miniature 7& 9 pin(the 9 pin socket is actually a 9+1 ... moreB10G type that can accept 10-pin tubes such as the 6C9) Nuvistor Novar(9-pin Compactron type) Compactron(12 pin) Most tubes with the above socket types can be tested with this unit. To test other tubes(e.g. 4- 5- 6- and 7-pin large base tubes) you would need a socket adapter. Please let me know if you have specific tubes you need to test and I'll let you know if they're in the test charts. The meter has some marks as shown in the pictures. But is easy to read. The case and hardware are in good shape with only minor marks and nicks. The fold-down handle/foot has some tarnish, but works well both to carry the unit and to support it at a convenient angle during testing. Let me know if you have any questions. NOTE: Any tubes under test are for demo purposes and are not included in this sale.

Precision Apparatus PACO 612 Tube & Battery Tester, Calibrated Fixed Tested NICE
Here is a very nice PACO tube tester. It's the Model 612 tube and battery tester. I haven't done much with PACO gear(though I'm totally dependent on their C-20 capacitor tester) But based on the shiny chrome faceplate this looks to be a later production run of the venerable 612 emission tester. This is a nice tester. It beats my trusty old EICO 625, that's for sure. I toyed with the idea of swapping out the 625 for the 612 for my quick bench tester. still might happen. We'll see how the sale goes. This tester has the following sockets: Octal Loctal 7& 9 Pin Miniature 4. 5, 6& 7 Pin Large Base Acorn Subminiature(8-pin pencil tube) 7 pin in-line Subminiature It will test most. If not all, rock and roll tubes and antique radio tubes including 12AX7, 12AU7, 12AT7, 6BQ5(EL84) 6CA7(EL34) KT-66, KT-88, 6550, 5881, 6146, ... more7025 etc. I tested a tube in every socket. I have a standard weak 6CA7(EL34) that I use to judge testers. This tester got it right. Checked leaky and good capacitor. The 612 had no trouble identifying which one was which. The battery test also worked. I am confident this tube. Condenser and battery tester is fully functional. The meter is very nice. The movement is very smooth and repeatable. Overall. This unit very nice as you can see from the pictures. The case has some scrapes and marks but is very solid. All feet are there. They're not a exact match but close. The handle, latches and hinges are very nice and fully functional. If you like PACO tube testers. See the 654 I've got listed in the Vintage Electronics category. US Only. UPS Ground is quoted. But might ship via Priority Mail if it makes sense. Don't know, this thing is pretty heavy. Alaska& Hawaii please contact me for shipping quote. Tubes shown in pictures are demo only. They are not included in the sale. Let me know if you have any questions.

Knight KG-600 Tube Tester Upgraded to KG-600A w/ 600B Chart Calibrated Tested
Many items on ebay have stories to tell. Some are happy. Some are sad. This is one such item. If you're not interested in my making a short story long. Skip ahead to the executive summary. Back in the days when vacuum tubes reigned supreme. Knight, a division of Allied Radio, was the maker of many wonderful test instruments. The KG-600 series of tube testers was a proud member of this family. This fine Knight Tube Tester was born a Model KG-600. But soon after the release of the KG-600, many new tubes hit the scene, most notably the Novar and Compactron types. Knight engineers quickly and very ingeniously designed an upgraded tester, the KG-600A, that was just like the 600 but would also test the new tubes. The ingenious part of the design was that the 600A and subsequent 600-series testers didn't add any more lever switches. The ... moreKnight engineers figured out how to make the same old 10 lever switches perform tests for the additional 2 pins in the Compactron tube base(12 total) Most, if not all, tester manufacturers went with a 13 lever design. 13 lever switches would allow for 12 pins plus a grid cap. Some prior owner of this fine instrument realized how easy it was to upgrade the KG-600 to a KG-600A. Because the same KG-600 circuit with its 10 lever switches was able to test the new tubes. All you had to do is add the new tube sockets and wire them properly. And wire them properly they did. With the exception of drilling the Compactron socket chassis hole a bit too large, they did an excellent job of it. They even installed a KG-600B roll chart in the instrument. This new roll chart had an enhanced grid test procedure that also included a gas test. It was an excellent idea. Here's the sad part. For some reason, the meter lens was removed when the new tube socket hole was drilled. When I bought this tester, the meter movement was packed with tiny iron filings- like what you would get when drilling a hole in the steel chassis. The needle was stuck! It wouldn't budge in any direction. The permanent

Hickok 799 Mutual Conductance Tube Tester- Works Great- Calibrated& Clean Hickok 799 Mustang Dynamic Mutual Conductance Tube Tester Looks great. Works great, and calibrated. The Hickok 799 Mustang is Hickok's only Solid State tube tester that they produced. This particular unit has had one upgrade which is a new capacitor on the meter. The one removed was good and will be included. The tester is calibrated per the calibration instructions and works perfect. The unit itself is in great condition as you can see in the pictures. The Hickok 799 Mustang includes the instruction manual(dated 1965) and tube data that is in addition to the tube data on the unit itself. The tester does measure micromhos but does not provide a direct number for micromhos and uses a good and bad scale for Gm with numbers up to 1000. You can still match tubes ... morewith this unit. The tube being tested in the pictures is a 6L6 calibration tube with 5475 Gm. The P1 button tests tubes for Gm that should have a reading up to 5000 micromhos and the P2 button tests tubes for Gm that should have a reading up to 20.000 micromhos. It is a beautiful tube tester and it is a true Hickok that tests Gm. Take a look at the pictures of the inside and you will see it is all Hickok and beautifully constructed. There are no expensive tubes that have to be replaced and it is simple to calibrate. Documentation for tube data.

EICO 625 Tube Tester, Repaired Recapped Calibrated Tested, Accurate All Works
The EICO 625 Tube Testers are easy to use. Accurate and reliable. That's what made them so popular. Another reason the EICO 625 was so popular is because it will test a lot of different tubes. And if the sockets it has aren't enough. Then adapters are available that will test almost every consumer tube ever made. This unit comes with a bound copy of the Instruction Manual. Assembly Manual and lots of test setup charts. One of the charts has an exhaustive list of tubes and includes tubes tested with an adapter. I repaired. Recapped, calibrated and tested this instrument. I cleaned the sockets and switch contacts. Everything works. The switches and sockets are tight and the meter is smooth and repeatable. It calibrates to line very nicely and identified my weak EL34. Good tubes tested good. Short and leakage indicator has a new neon ... morelamp and works well. The roll chart mechanism isn't the best I've seen but quite workable. It looks like the roll chart has sat for a long time in one position and one section of it has some dark spots. Everything is still very readable. On the plus side. This is the most recent roll chart I've ever seen. It's the EICO 625-10. It also has a green roll chart window. The window is nice, but I don't think it's an EICO original. The knobs and grid caps are in good shape. Overall this unit is clean. But has tarnish and marks. The faceplate also has marks. It's best to look at the pictures for a better idea. Tubes shown in pictures are for demo and don't come with the tester. US Only. UPS Ground is quoted. But might ship Priority Mail if similar cost. Alaska and Hawaii, please contact me for a shipping quote. Let me know if you have any questions.

B&K 700 TUBE TESTER CLEANED SERVICED AND CALIBRATED
Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 The B&K 700 is the ultimate professional-grade tester for any user that values his or her time and appreciates convenience. This tester has been calibrated and cleaned. This is what was done: Cleaned all switches and tube sockets with Dexoit contact cleaner; Replaced all electrolytic capacitors. This is a must do. The capacitor has electrolyte oxide layers that will break down and rupture after 15 years. The last 700 was made in 1960 so the life of the capacitor has expired. This issue alone will put the tester out of calibration. I checked all voltages and bridge resistors; Made all service adjustments according to B&K standards; Adjusted operation of short detection and leakage circuitry. Grid emission, signal voltage, DC Bias balance and balance control. ... moreI have made 12AX7 modification that greatly improves this test. Tester comes with the Instruction Manual, Tube Chart and plate cap wire. What are my qualifications? I taught electronics at a local Technical College for 20 years and have a FCC technician license. Features a clever voltage control circuit that eliminates the need to constantly set the AC line level to insure accurate tests. Regardless of line voltage variations.

Hickok 800a Tube Tester - Calibrated - Plate Current mod - Quick Cal Mod
Hickok 800A tester- Calibrated- Plate Current Mod- QuickCal Mod. Cosmetically the case is a little rough and the meter face somewhat faded. But the tester is calibrated and working well. Price reduced accordingly, if you not looking for museum quality case, and just want a good working calibrated tester this might be the one for you. The electronics inside are very clean. Please see photos for more details. Note- the 800A tester has the extra sockets to do the compactron tubes(without a separate adapter) It is also one of the few Hickoks that can measure tube leakage on the meter! The tester has been modified to test Plate Current using the diode test points just under the meter. Instructions on how this works included. It is important to test idle current when matching power tubes for class B or AB operation. The diode function is intact ... morejust not hooked up and can be hooked to a 1/8" jack if needed and retain the plate test. But any modern DMM can test diodes, while tube testers that can test plate current are rare. This tester is the newer vintage of the 800A with the voltage set pot(see blue dial in interior pictures) This tester has been upgraded so that the clunky adjustment rig R15 for bias and reduced screen voltage can be quickly and easily set. Calibration results- Plate Voltage = 151(nominal 150 +/ 5V) Screen Voltage = 132.6(nominal 130 +/ 5V) Reduced Screen = 56.2(nominal 56v +/ 3V) Bias-39.1(nominal-39.3v +/ 1V) Bias@22 =-3.0(3.0) Leakage test= pass. Filament 6.4(6.3) 12.4(12.6) AC Signal= 2.5V(2.5) Very nice results for this field tester! A Noval and Octal socket saver have been added to ensure the most common tubes test well. A regulated Solid State 83 replacement has been included to ensure stability and long life of the tester. The roll chart turns well and is dated"Fall 1968" But I have also included all documentation and test data(including some error fixes) that I have for this model on CD so you don't need to use the roll chart, and can preserve it.

Daven I-177B Military Mutual Conductance Tube Tester, Calibrated, Works Great!
Daven I-177B Military Mutual Conductance Tube Tester. Calibrated, Works Great! Daven I-177-B U.S. Army Signal Corps Mutual Conductance Tube Tester The 83 is a JAN RCA. The 5Y3GT is a JAN Ken Rad and both are as good as new. With a 6L6 in the socket the filament voltage is 6.31 VAC which is critical for correct Gm test results and calibration. Many Hickok testers will drop below 6 VAC with a tube in the socket causing inaccurate Gm results. The 6L6 being tested in the pictures shows a Gm reading of 5500 which is the exact same result on a calibrated Hickok 750. A new three-prong cord was added for protection. The original tube data is all there. Minus the cover page, and the original schematic is there. The MFP was done in 1957 so probably from that era. The manual and tube data are available at no charge in PDF at bama: and of course Nolan ... moreLee: I will also provide what I have in PDF as well if requested. The tester weighs 20 pounds packed.

B&K 607 Dyna Jet Solid State Vacuum Tube Tester, Setup Guide, Manual CALIBRATED
Up for sale is a repaired. Tested and working B&K Dyna Jet 607 Tube Tester. This unit is B&K's clone of the Sencore Mighty Might VII(TC162) You can see an excellent write-up of this unit at TubeSound's website: Overall. This tester is in decent condition and works. The lid has a crack in one of the corners and the case has seen some use. The case is a hard plastic and has held up well. For details of overall condition, please see the pictures. I tested every socket except#8 for which I don't have any tubes. I checked the wiring to#8 and it looks fine. In the unusual case that you need to test a 5BC3 tube. I'm pretty sure this socket will also work. The lockout switches and all controls work as they should. Everything tested worked as it should. I calibrated the short and grid leakage circuits. The short and power lights ... morework. The leakage and quality tests worked as expected for all the tubes I tested. As described in the TubeSound blog. I checked the test voltage-load combinations for all LOAD settings A through J. All voltages and resistive loads were well within spec. The original meter was broken and I replaced it with a new meter. It had the same rating but a different faceplate. So I made a faceplate for it to match the B&K original. The grid clip is also a new replacement and not original. Included with the tester is an original Setup Guide which is in good shape. A little dirty from use but very legible. Also included is a bound copy of the Instruction Manual. The manual includes a calibration procedure, parts list and schematic. The manual is easy to read, but the schematic is hard to read. Please let me know if you have any questions. USA only. No international sales. UPS Ground shipping is quoted but unit might ship by Priority Mail if there's not a big price difference. Tubes shown are for demo purposes only and are not included in the sale.

B&K 707 TUBE TESTER FULLY CALIBRATED READY TO USE
The unit is rough on the outside. But it is a very solid case. To look new it could be painted or recovered. On the inside as you can see from the pics, it is very clean, actually looks unused. The tester was in storage for a few years and so before I decided to sell it I had it calibrated. Before it was calibrated all of the capacitors were replaced and all od the resistors were checked for out of tolerance. There are two#55 lamps in there in bayonet sockets that have proven to be faulty after some time so to remedy this the bulbs were soldered into the sockets. Then it was calibrated to spec and tested with many tubes of known condition. It was right on the money. Included with it will be a copy of the original tube manual. Works perfectly and is priced to sell.

Hickok 539-A / 539A Tube Tester - serviced and calibrated
Hickok 539-A Tube Tester calibrated This Tube tester was serviced with new resistors. Caps and complete adjustments for correct signal levels and meter bridge setting etc. I also replaced the 83 Rectifier Tube with Solid state replacement to reduce the load on the transformer. 539 A is the earlier version of 539B/C and has almost the same features like Self bias terminals and Plate Current Measuring terminals etc. Also signal level can be switched unlike entry level 600 A or 800A versions. This model can be a versatile Hickok like 539B or C without fancy price. Plate Voltage. Screen, Grid Bias and Grid Signal levels were checked after adjustments. also the Meter bridge was adjusted for correct meter reading for Micromho based on Daniel Schoo 539 C calibration method on all ranges. I also checked a known calibration sample 6L6 for correct ... morereading along with few 12AX7 tubes. All are showing correct reading. I also use Brent Jesse Recording Sample calibration 6L6 tube for checking this tester. Few points to note. This tester will not be shipped overseas due to fragile as well as size of the tester. The wood was the original 539 A box but the covering was really not worthy of this tester when I got it. So I removed the decayed covering. The wood box is not of great quality( as Hickok boxes were meant to have the covering to make it look better than bare wooden box. The buyer can get it covered using Tolex or suitable material. I had done such a work on 800 A model and can guide the buyer if he wishes to do on his own. This tester is over 50 year old and hence the top looks its age. However I had replaced the power cable with 3 pronged safety 3 wire power cabling. The earth is connected to the top Metal plate to avoid issues with power input. Please ask qu estions before bidding I tem will be shipped with insurance and the shipping costs are reasonable for the size and weight of this item. Considering the effort to service and calibration the reserve is reasonable and buy it now is good bargain. I travel for my regu

Here is a mutual conductance tester you can be proud of and count on for decades to come. A beautiful refubished, calibrated, and improved B&K 707. This one was from Glendale Union High School, Phoenix, AZ(see pic of original condition) and has not seen much use- a great thing! Very well preserved and super clean from that dry climate. It has been carefully cleaned and polished. Completely re-capped with Sprague Atom and Illinois(4 caps) resistors checked, meter circuit checked, tubes checked and 83 tube replaced with silicon diodes, unit fully calibrated(adjusted shorts detection; leakage circuit, grid emmision, signal voltage; dc bias& balance all according to B&K instructions) checked DC plate voltage& DC screen voltage. Then 12AX7 and 6BQ5 modified. This 12AX7 modification brings the correct bias voltage to the new 12AX7 ... moresocket(number 24) for test results we want and expect to see- ranging from 0 to 120. Not 0 to 30(with 22 min good) as is stock. A wonderful modification as no one likes the design defect of the 22 min 12AX7 testers(all B&K, Hickok, If you want to test the old way though, it is still there available on socket 8. Either way you test each side of the 12AX7 with test buttons 1 and 2, no need to reset any controls. 6BQ5 new bias also brought to 6BQ5 test socket to give you a more accurate test.

Military TV-7A/U Mutual Conductance Tube Tester - Refurbished, Calibrated
This tester was my own for many years. It has not seen difficulty duty. It has no dents or dings. But the paint is of course nicked in places due to its time in the Army. I've included a fresh(Oct/2014) calibration. The 83 rectifier tube tests almost as new. All controls are intact and not chipped or broken. Calibration using Nelson Cal tubes was excellent. I also tested it against my Hickok 752A tester and my TV-10D/U tester. All sockets are tight. You won't find a better example of the TV-7A/U anywhere. DESCRIPTION Refurbished& Calibrated TV-7A/U Military Mutual Conductance Calibration on a tester costs approximately $245- you are getting that as part of this auction and the test result sheet is included. Tester is ready to go- nothing for you to do. Tester Schematic(as printed by Hickok) original to this tester was glued to ... morethe inside base of the unit. I removed it because the back was starting to deteriorate. But it is included and was laminated by the manufacturer. You won't find this in many of the 7/Us out there- long gone! Has the advantage of being able to test older tubes as well as newer styles. Tests for Mutual Conductance. Leakage, Gas, Noise, and Remaining Life. NEVER TEST FOR MUTUAL CONDUCTANCE BEFORE DOING A SHORTS TEST! Military Construction by Hickok. In a very compact aluminum case. Highest Quality Components- They continue to work many years after manufacture- a testament to their quality. Calibration Results Shown in Picture and included. Additional test manual included(Blue manual) see pictures. Original manual in the lid is in good condition also. The power lead has not been replaced- never saw a need to. It is in good condition. A three prong cord and plug could be fit to it. But there really isn't a need to do so. INCLUDED Test Data Booklet in the lid(original) Test data and manual reprint(blue) bound. Two test leads(as original had) Two pin straighteners mounted in lid. Four(4) tube adapters. Laminated original mfr schematic. Calibration Sheet. PAYMENT& SHIPPING

TV-7A/U Military Tube Tester with Digital Meter Serviced & Calibrated Dan Nelson
Military TV-7A/U tube tester. The tester was fully serviced and calibrated by Dan Nelson in March 2014 and has been an excellent tester but I have 2 of them and only need 1 so I am selling this one. I had the didital meter installed for better accuracy and took photos of the invoice from Dan so you can zoom in and see for yourself what was done and the digital meter is by far the best way to go on these testers and I love it and as you can see it was not cheap but well worth the money. The switch& socket panel is in excellent shape with very minimal to no wear and the outer case is better than most. Also it has been upgraded to the 3 prong grounded power cord for safety. It is missing the tube test data book. The rings for the book and the adapters for the odd ball tubes that I have never needed anyway so I removed them so they were out ... moreof the way and now cant find where I put them and you are better of to get the latest updated copy of the test data from here on Ebay anyway as it is much easier to read and has more data and they are cheap. So any questions please feel free to ask and thanks for looking and good luck.

B&K 747 PRECISION DYNA-JET TUBE TESTER + ReCapd + CALIBRATED &Full Scale 12AX7
From my personal collection. Here is a mutual conductance tester you can be proud of and count on for decades to come, a beautiful refubished restored and calibrated B&K 747. This one is originally from State of Connecticut, Dept of Education and has clearly not seen much use. Very well kept and super clean, no rust nor corrosion to be seen. Last of the 747 testers, late production date on this one is July 1982(as seen in the closeup. This 747 was very recently fully calibrated(adjusted according to B&K procedures- shorts detection threshold. Leakage circuit, and grid emmision circuit. Then checked and/or adjusted for correct signal voltage, DC bias& balance, DC plate voltage& DC screen voltage- again according to B&K procedures. Importantly, the electrolytic caps were all replaced with USA manufacture Illinois caps. This ... morewill assure the new owner of stability for decades. Resistors were also checked and/or replaced for correct values. This 747 does not need to be 12AX7 modified. Test results read full scale on the meter now. Uses test buttons 1 and 2 to check both triodes so no need to reset any switches to read the other triode within. Try that with your Hickok, no can do. Automatic line adjust circuitry too, no more line adjusting for each tube type. Truely exhibits ease of use when testing many various tubes at one sitting. Photos are not generic 747 pictures. As you can tell, and the winner will receive the exact beautiful unit pictured. This 747 is not for the average bench, rather for the discriminating buyer who wants beauty, dependability, and accuracy all wrapped into one premium tester. Time was spent carefully cleaning and polishing the tester face plate. Not that it needed it much. The excellent condition outer case was also gently cleaned. Check the pictures for shine and reflection. Lid hinges& latches work smoothly and solidly, 100% good. Original set up chart is in the lid- nice. I will also email the winner a pdf file of the original 747 operating manual. Will test 6LQ6 6

I-177-B Supreme CALIBRATED AND MX-949A/U Tube Tester Adapter Excellent Condition
This is an absolutely amazing combination and for the I-177-B to have been recently calibrated. Well, that’s like the icing on the cake! I have checked this against my Dan Nelson just calibrated TV-7 and this tester is right there with it… SO accurate and it reads in Microhos! Now in combining this tester with the MX-949A/U adapter. Which was made for the I-177-B, you can test big amateur radio transmitter tubes right on down to the small 7 pin tubes. Both units have very tight controls, socket pins and it is obvious that they saw very little use. The calibration sheets for the I-177-B will be included as well as additional testing information, including documentation for using the MX-949A/U adapter. You won’t have another opportunity to buy such a fantastic combination as this, so make sure you don’t let this one slip by! Disclaimer: All ... moreused electronics are sold AS-IS to the buyer. Most of the items are 30 to 60 years old and often times older. I do my best to check them out and describe them accurately both cosmetically and electrically. But due to the fact that most parts are original, I cannot tell how long these parts will last. Vintage electronics may need capacitors, tubes or alignment, sometimes they work just fine. Shipping to the lower 48 states only. Paypal address must be confirmed. Shipping by FedEx insured and packed very carefully.

Hickok 750 tester - Calibrated - Plate Current Mod - QuickCal Mod
Hickok 750 tester- Calibrated- Plate Current Mod- QuickCal Mod Working and calibrated Hickok 750 Tester- This was the replacement for the 539 Series. Roll Chart Dated 1972. This is the newer model that can test for leakage on the meter itself. This can be easily identified by the pilot light in the center of the tester. The older model had a shorts light in that location and the pilot light near the on switch. The tester has been modified to test Plate Current using the black noise test points in the center of the unit. The noise test has been retained and hooked up to a 1/8” socket. Shown between the two black test points. Instructions on how the plate current test works is included. It is important to test idle current when matching power tubes for class B or AB operation. The slider calibration adjustments have been replaced with pots ... moreto ensure easy and quick calibration. Calibration results- Plate Voltage = 150.0(nominal 150 +/ 5V) Screen Voltage = 133.2(nominal 130 +/ 5V) Reduced Screen = 56.0(nominal 56v +/ 3V) Bias-39(nominal-39v +/ 1V) Bias@22 =-3.0(3.0) Leakage test= pass Filament 6.4(6.3) 12.5(12.6) Noval and Octal socket savers have been added. A regulated Solid State 83 replacement has been included to ensure stability and long life of the tester. There is a new 5Y3 tube that should last many years. The 5Y3 socket may need to be replaced someday. I have jumped a couple of connections to ensure stability and proper current flow. The socket is riveted in place and I do not have the proper tools to drill that out. Given that I get testers in that have 50 year old 5Y3 tubes that are still working this will probably outlast you or I as it is now, but wanted the buyer to be aware. I took this unit on a road trip with me recently it is solid should be transportable when needed if done so with care. I do not own or use any voltage regulator tubes so the accuracy of those test functions are unknown. The case is in good shape for its age with no large tears but the covering is curling up

Excellent condition TV-7 A/U. Recently refurbished- all switches cleaned. Critical caps, resistors, and diodes replaced. 7/9 pin sockets and the 83 tube were replaced by Dan Nelson when he had the unit for calibration(completed in Nov. 2014) This is a great unit- everything works well, and the calibration came out very accurate.

It's been to Dan's for calibration already so I'm set and don't really need two of these. As you can see by the pictures, cosmetically, the unit is in well loved condition but also note the photos of the internals- super clean. The unit will be very well packaged- I prefer to ship FedEx but will go with your preference if you have one. PLEASE NOTE: NO INTERNATIONAL ... moreSALES OR SHIPPING!

They were also sold to the US Government by the thousands, to be used in critical applications, such as planes, tracking equipment, etc. so you know they had to be built to work, and keep working. There are many stories out there, some apocryphal, I'm sure, about these testers surviving floods, mud-slides, extreme rust, extreme heat, you name it, then being plugged in- only to find out they still ... moreworked. Oh, make no mistake, they do and did break down- but it usually took a lot of use and/or abuse to cause that. This tester has some very nice features. Including a test for(relative) remaining tube-life, the ability to test dual-triodes without changing settings, the ability to set exactly accurate plate-voltage that the tube was designed for, the ability to measure the tube's reading in micromhos, test and measures shorts and leakage in the tubes, and much more. One thing it will not do: it will NOT cook your dinner for you(you need a significant other for that) well, maybe it would cook your dinner ONCE- but then, you'd need a new tester.Seriously, though, this really is considered a professional unit. This unit was sent to the well-known Roger Kennedy of All Tube Testers dot com. Who inspected, cleaned and calibrated it in May of 2014. It is in relatively decent condition cosmetically for an instrument which is more than 50 years old. We are selling this tester in good faith that it is in working condition(although it might take you a while to figure that out, if you're not familiar with this line) and because of its age, we are selling it as-is, and wil

Hickok 6000A Mutual Conductance Tube Tester - Calibrated - Late Model & Manuals
Hickok 6000A Mutual Conductance Tube Tester- Calibrated- Late Model& Manuals Hickok 6000A Mutual Conductance Tube Tester Calibrated and in Excellent Working Condition All Voltages Within SPECS that can be seen in the pictures below. All tests were done with the correct shunt resistor to duplicate 1.000 Ohms/Volt Meter. Picture 3 shows the AC signal voltage 2.50 SPEC is 2.5 +- 2 Picture 4 is the plate voltage of 152.5 SPEC is 150 +- 5 Picture 5 is the screen voltage of 135.3 SPEC is 135 +- 2 Picture 6 is the low screen voltage of 56.4 SPEC is 56+- 2 Picture 7 is bias voltage at 100 which is-39.1 SPEC is-40 +- 2 Picture 8 is bias at 22 which is 3.33 SPEC is 3.3 +- 2 Picture 9 shows the filament voltage with the tube in the socket at 6.14 which there is no SPEC for. But critical to get accurate test results. Many Hickok testers can be calibrated, ... morebut the heater voltage drops below 6 volts when a tube is in the socket causing in accurate test results. Picture 9. 10, and 11 show a 6L6 calibration tube with Gm of 5475 being tested with the same results of 5475. The needle is between 5 4 50 and 550 0 on the tester. Please look at the pictures and ask any questions. The tolex is not in great shape but the case is solid. The shorts test is automatic and works. The 83 and 5y3GT are as good as new and balanced. This tester. With the tube plate currently on it, cannot test older tubes such as the 4 pin. Please be sure you know if this tester will work for your needs. If you can find a tube plate for a 6000, you will be able to test the older tubes with this tester as well. This is a later version of the 6000A that came with a newer style meter. An adjustable pot on the meter, that has never been adjusted, an adjustable pot, R17, for the signal and plate voltage, which makes it a lot easier to calibrate than earlier models. The roll chart is dated 1968. Information including calibration procedures. And updated tube data are readily available at no charge at Bama and elsewhere. Please ask any questions and look at the

HICKOK 800A DYNAMIC MUTUAL CONDUCTANCE TUBE TESTER RECENTLY CALIBRATED
This is a very nice Hickok 800A. Which is the later and more desirable of the 800 series. The case is very presentable, though has some normal wear. The tester deck is quite nice and crisp detailing as you can see in the pictures. The electrical condition is excellent and has been recently calibrated and tests very close to my Dan Nelson calibrated TV7’s. In the pictures. You’ll see line voltage being set and then testing a 6L6(tube not included) T he roll chart moves well from end to end with the typical Hickok tightness at the either end. You’ll have to look long and hard to find another 800A in this nice condition and surely have to would pay much more. The 800A was purchased as a backup and since I don’t normally use it. It deserves to go to someone who appreciates a higher quality tester. The pictures tell a better story than I can. ... moreSo please do look. Your tester will be shipped FedEx in an oversized box and carefully bubble wrapped, protected well and insured. I ship ONLY within the Lower 48 States. NO overseas shipment. PAYPAL verified address and PAYPAL Payment*

B&K 747 CALIBRATED Tube Tester, VERY NICE !
You are bidding on a B&K 747 Tube Tester that I have taken the time to check it all out: apply contact cleaner(DeOxit) to critical switch contacts; inspect for any bad parts(there were none) spent the time to go through the detailed B&K calibration procedure; clean it all up and then use my"tried and true" calibration tubes(6AU6& 6L6) to VERIFY the tester is actually reading correctly(they were! I think you already know this is a"High End" Gm Transconductance. Totally solid state(no tubes) design, very simple and fast to use, test's about 96% of all tubes, including the audio 6EU7& 6K11 and pretty much ANY other audio tube. A copy of the manual, setup chart and the plate-cap patch cord, is included. FYI, the setup chart is dated 1981. I know you will love to have this great and ready to go, tube tester. ... moreTHANKS, 73's

EICO model 625 tube tester; updated, calibrated, and works great!
Here's a nice Eico 625 tube tester. Many were kits. Others were factory-wired. This particular one works great; I tested 12v tubes, 6v tubes, and in the pics a 5Y3; the results were accurate. If you're into matching audio pairs/quads, this isn't the instrument for you; you'll need to fork over a few hundred bucks more for a mutual-conductance tester. However, if you want to get the old Magnavox, Zenith or Philco playing again, this tester will surely help. NOTE: IN THE PICTURES. THE SCREWS ON THE FACEPLATE AREN'T THERE. REST ASSURED, I'LL RE-INSTALL THEM! I removed them to photograph the innards of this instrument. I figured you'd want to see what's inside.

Mint Calibrated Stark 12-22A Mutual Conductance Vacuum Tube Tester Hickok Tester
This calibrated Stark Model 12-22A Dynamic Mutual Conductance Tube Tester is probably the hardest vacuum tube tester to find. It tests both European and American Vacuum Tubes along with Selenium Rectifiers. Transistors and Diodes. Stark was the Canadian subsiduary of Hickok and made electrically identical tube testers. Using the Hickok circuits, but with a somewhat different appearance, and a lot wider range of sockets. The quality is second to none. The bias pots etc. feel very healthy. Function switches look and feel great. Both are somewhat bigger than their hickok counterparts. To allow for the extra sockets. A Stark 12-22A Users Manual. Calibration instructions and a Hickok Consolidated Test Data Manual is Included. Both the Hickok 533A and the Stark 12-22A use the same 2.5 Screen Voltage so they share the same Tube Testing Data. Resisters ... moreand Capacitors were checked and replaced as necessary. The 83 Mercury Filled Rectifier Tube has been replaced with a perfectly balanced solid state replacement. The 5Y3 tested new and balanced. This tube cannot be replaced with a solid state replacement without loosing accuracy. Calibration double checked with 6L6 and 6sx7 Calibrating Tubes. Then Tripled checked matching tubes on a Calibrated Hickok 533A.

Calibrated and rebuilt - RCA WT-110A automatic vacuum tube tester card cardmatic
You are bidding on a RCA WT-110A vacuum tube tester. This tester was recapped and calibrated by the previous owner last year. I have owned this tester for a few months and can attest that it works very well. This tube tester uses cards to set up the parameters for the testing. All the cards are located in the tester. And you flip them into the card slot below the panel meter. No more fiddling with dozens of knobs and levers. Included with the tester is a card punch. The schematic and the manual. It will be packed well for safe arrival.

Military TV-7D/U (TV7D, Hickok) 7B meter, calibrated and refurbished
This is TV-7D/U. Which was repaired with a TV-7B/U meter at some point before I owned it. I recently had it refurbished by Steve McKinley of Atlanta Tube Amp so it should be good for a while. He confirmed that this tester has the 7D circuit. The condition is okay considering age, but it is definitely not flawless. The case has some scratches. The acorn socket would have to be repaired if you want to test acorn tubes. I have never needed that socket. It comes with an original manual and one adapter as shown. I show it testing a used EL 34 and a used 6922. Returns are accepted if not as pictured/described. I will open to international shipping if it doesn't sell at listed price. Edit: Added brighter pictures. Also. I just received the tester back from Atlanta Tube last week so it should be under warranty for another couple of weeks. Shipping ... moreis approximate, but I will refund if it is less than expected. Other shipping options or local pickup in Atlanta is also possible. Thanks for looking.
