Heathkit IT-21 Tube Tester- Nice! Accurate! HAM Here's a nice. Clean Heathkit model IT-21 tube tester. It has all the sockets you've been looking for to test the tubes in your vintage radios. It'll test those older 4-pin, 5-pin, 6-pin, and even 7-pin tubes, as well as the later 8-pin Octal, 8-pin Loctal and the 7-pin and 9-pin miniatures. It also has sockets for both 5-pin and 7-pin Nuvistors, 9-pin Novar tubes and 12-pin Compactrons. The 9-pin miniature socket has an additional center pin to also accept 10-pin miniature tubes. The test circuit of the IT-21 is identical to Heath's later models IT-17 and IT-3117, and the earlier"TC" models, and the test data for these testers is also usable with the IT-21. To ensure accuracy of a newly built kit. Heath didn't provide any calibration adjustments for this model ... moretester, relying instead on the inherent accuracy provided by using close tolerance components in the measuring circuits. All the components of this instrument have been checked for accuracy and found to be well withing their original specifications; and this TC-3 is working as it should on all ranges. It is shown in the second photo testing a new 6L6GC tube. The tube, of course, is not included in the auction. This instrument is especially nice. The workmanship is impeccable and very neat with proper layout. The connections and solder joints are professionally done. And it even has the little"extras" like laced wiring not usually found on a kit instrument. The workmanship of this instrument is as good as I've seen on any electronic instrument- even the expensive professional stuff. The interior is free of corrosion or other damage, and the face of the tester is also in very good condition. The tester ships with a clean re-print of the operating and maintenance sections of the manual. Including the schematic. Only the detailed construction steps have been omitted. Also included is the last Tube Data Book, published in 1978. It contains 49 pages of data- much more dat
Nice Clean Heathkit IT-21 Tube Tester. I don't have any tubes to test this, but the collector I got it from said it works like it should, 14 day return if not satisfied. Buyer adds exact USPS shipping
Up for auction is a Heathkit Tube Tester Model IT-21. This tube tester is in excellent cosmetic condition. There are minor scuff and scrapes on it. But nothing out of the ordinary for a vintage piece such as this. There is a knob missing on the lower right side and on the bottom of the unit the caps on the A& L levers are also missing. It is missing two foot pads on the left side and also on the back side it is missing one foot pad on the top left side on the back of the tester. Other than those few flaws, this is a very clean unit that has been tested and all knobs and switches and plugs& plug-ins appear to function properly. I was not able to test every bulb socket because I did not have all the sizes, I did have 7 different bulbs a few different sizes and each worked so I assume all the other sockets do too. I honor my products ... morethough so you can bid with confidence knowing that if there does end up being a problem with a socket I was unable to test I will take care of it. If you have any questions or concerns about this vintage tube tester, please mail me and I will respond quick and honestly, thank you! Happy Bidding! P.S.

This is a model IT-21 tube tester made by Heathkit. It is in excellent condition and is working very well. This will test 4. 5, 6, 7 prong older tubes, 7, 9, 10 pin miniature, octal, loctal, nuvistor, 9, 12 pin compactron, and pilot lights. Some of the tubes this will test are O1A, 6l6, 6550, 12AX7, 7591, 45, 50, 71A, 6SN7, and hundreds more. Notice the 3 tubes I tested with this tester. I even tested a known weak EL34 and it tested bad. All filament voltage selections on the switch were tested. The plastic window has come un-glued over the tube chart roll. I will include this if you decide to put it back on. Tester front panel shows a little normal wear. Case looks great. Unit is un-restored, and un-modified. All contacts and switches were lubricated with De-Oxit. I will include the original manual and a copy of tube settings book. If for ... moreany reason there is a problem whether it is with the item.

Heathkit IT-21 Tube Tester- Tested and works! Bought from a ham buddy. Was using it. I cleaned the pots and switches and tested my tubes. Roll chart works, laying down better than sitting upright. The window is loose, and will fix that. Its a nice looking unit, some scratches and dings, but nothing big. Shipping is USPS, to your site. I can repair and clean these and other tube testers, if any ones interested! Powered by The free listing tool. List your items fast and easy and manage your active items.

I do ship internationally. But will NOT lie on customs forms about value, please do not even ask me to do this.Thanks.
This Heathkit IT-21 Tube Tester- Checker is from an estate so we don't know about its history. But appears to be in pretty good condition. It really only needs to be cleaned up a bit, but we will leave that to the new owner. The knobs all turn freely and the levers all move securely into their three detent positions. Regardless of it they have a knob or not. The thumb-wheel on the right moves the tube selector drum. But we don't know what the thumb-wheel on the left is supposed to do. The area in front of the tube selector drum is open. But we don't know if is supposed to be open or not. We powered it up and the panel lights illuminate. And as seen in the photo, the meter needle centers on the scale for Line Test. We have no tubes to test it with, so it is being sold as is, untested. NOTE: The item in the photos will be what you ... morewill receive. Please see our other auction for a Heathkit SW 7800 Receiver from the estate.

Seems to work fine but I don't know much about them. I tested a bunch of tubes and so I think it's fine but I have to sell it as-is since I don't know how to test all the functions. There's one cable that I showed in the second picture that is clipped off. I have no idea what it's for. The color in the second picture is actually more correct.I didn't use a flash in the first pic. There's a dent in the lower left corner as shown. Ask any questions you like. Thanks for looking!
Here for your consideration is an Exceptional Heathkit IT-21 Transconductance Tube Tester that looks like someone just finished building it in 1964. This is one of the best and most versatile tube testers ever made. This 13” x 10” x 6” tester has 12 sockets and covers a very wide range of tubes from the earliest 4 pin tubes right through sweep tubes and compactrons. Very few testers do this whole range. The IT-21 was offered by Heathkit from 1962 to 1964 and sold for $44.95 as a kit in my 1964 Heathkit catalog. This tester comes with the Heathkit Assembly Manual. Its internal roll chart, and Supplemental Test Data Sheet for use with the Heathkit IT-21 Tube Tester. I took this to my Tech friend Tom, and he replaced the line cord and the electrolytic capacitor. This should be ready for years of use. On the internal roll chart I see hundreds ... moreof tubes like 0A2, 1L6, 1LA6, 1R5, 1S5, 2A3, 5U4, 5Y3, 6A7, 6AC7, 6AQ5, 6AU6, 6B4, 6BQ5, 6C10, 6CA7, 6CL6, 6CM6, 6CZ5, 6E5, 6F6, 6HF5, 6JB6, 6L6, 6ME5, 6Sl7, 6SN7, 6U5, 6V6, 7A7, 12AU7, 12AX7, 12BH7, 12SN7, 12V6, 25L6, 35B5, 35Z5, 42, 50C5, 75, 80, 83, 84, 807, 811A, 866, 1612, 1614, 1619, 5881, 5963, 6146, 6550, 6883, 7025, 7189, 7199, 7868, 9002, and 9003. In the supplement book there are another 500+ tubes including 00A, 01A, 10, 10Y, 12, 24A, 26, 27, 45, 47, 50, 71A, 99, 274A, 300B, 310B, 407, 950, 9001, HY69, PX, RK33, RK34, VR-150, and WX-12.

HeathKit IT-21 tube tester in nice working condition as shown in pics. This is a good standard tube tester for testing your audio tubes. It comes with a nice bound copy of the tube data manual and is just a nice tube tester that you'll be happy with. It does have a chip out of the plate cap connector. Not that matters but thought I should mention it. Thanks and enjoy. RcmdId ViewItemDescV4,RlogId p4%60bo7%60jtb9%3Fvo%7B%3Dd70f%2Bf54%3E-1477f524c09-0x118-
