This bridge came from a business here in town that closed down and was used in a working environment. Unit deals with frequencies between 400 khz- 60 mhz. Direct Reading in ohms. Adaptable to coaxial connectors. Seems to be very similar to the"A" model whose user guide is readily available online. A bridge like this is intended to be used between a signal generator and null detector assembly for the accurate measurement of the resistance and reactance of antennas. Transmission lines, networks and components. Unit is untested by me. Auction is intended for someone with the knowledge to address any operational or performance issues with the unit should there be any. Being sold as is. Cosmetically has wear and some scratches with a stencil on 1 side. Obviously very high quality construction. Weight is 22 pounds Shipping is UPS Insured ... morein USA only. Good Luck!
Boonton Radio Corp. type 260-A Q Meter. Ham radio coil antenna In working condition. Feel free to make an offer! thank you!
Vintage Heathkit IT-2240 LC Meter From my personal collection. I acquired it from the original owner(a Ham operator that passed) He and I are not smokers. This instrument is hard to find in good condition. I used it for radio repair years back. But now it just sits on the shelf. Comes with original manual and calibration caps. Manuals binding is shot. However all is there including the foldouts/schematic. I would assume that a calibration check would be in order. I have never messed with it. Great to repair vintage receivers transmitters or add to your collection. Vintage electronics, sold AS IS. I will pack well to prevent damage. Shipping USA Only. UPS. Well packed, $24.00, If less, I will refund
Heathkit Impedance Bridge IB-1 Used. Exterior wood veneer is cracking, paint on face is chipping Untested 16.5" X 8" X 7" Check out my! Be sure to add me to your! Payments should be received within 7 days of the close of the auction and are accepted through PayPal only. Item will be shipped within 2 business days of the cleared payment.

Vintage Sprague TO-6A Capacitor Analyzer This instrument has been in my shop for 20 years. Have not used it for quite some time. I replaced the caps in the past. Works excellent since it has not seen much use at all. Magic eye is super bright and responsive. Comes with a manual. But it is a copy. These are great for checking caps in amplifiers plus Ham radios. You wont find a nicer one on ebay. Sorry to see it go. Vintage item. Selling AS IS. No returns. Very unique instrument. USA sales only! A street address is required for delivery. NO PO boxes. NO FEDEX, I will pack well to prevent damage. Shipping USA, UPS: $19.00
this appears to me to be in good condition normal wear the face/control panel i would say is in very good condition but i am no expert. It does power up that is all i can say, selling as is, there is no return for this auction, outside the U.S. must contact before bidding. please look at my other auctions for good deal and unique items. thankyou for looking at my auctions, it will be insured for the auction ending amount and proffessionally packed! free shipping is for the lower 48 states only.
This auction is for a vintage Heathkit Model IT-28 Capacitor checker/Resistance bridge. It contains the following tubes: 6AX4. 6BN8. And a 6E5 green eye indicator tube. I took the cover off and removed and tested the tubes. All tubes tested great! The 6BN8 had strong readings on all three sections and the 6AX4 had a strong reading. The 6E5 tube was bright green in both the open and closed positions on the tester. No further testing has been done with this instrument. So I am uncertain about it's calibration or general working condition. All the switches and knobs seem to work fine and it is in nice overall condition with just a little wear and staining. This item is being sold as pictured and"as-is" Take a look at all of the pictures for your best cosmetic description! Satisfaction guaranteed! $-$-$- Check out all the other ... moreitems I have for $ale! $-$-$* PLEASE make payment within(5) days of the auction ending. Thank you!
Powered by Boonton Radio 250A RX Meter For sale is a used and working Booton Radio Corp 250A RX meter. If your looking for one. You already know what it does. The oscillator output was verified across the frequency range with our HP counter as seen in our pictures. We do not guarantee this unit. As with all vintage electronics, you never know when an old component may fail. We powered up the unit and it seems to be working but we did not get the exact same result when we perfomed the same test set up with this unit and the newer HP 250B. We did not test the vacuum tubes. A section of the Capacitance dial is highly faded as seen in the pictures. Please bid accordingly This unit is either made to be rack mounted on standard 19" rack or it was modified to do so as seen in the pictures.

Powered by HP 250B RX Meter For sale is a used and working Hewlett Packard 250B RX meter. If your looking for one. You already know what it does. This one worked as expected when we bench tested it for this listing. The oscillator output was verified across the frequency range with our HP counter as seen in our pictures. This unit was also tested with a couple mobile ham radio antennas and the impedance was around 50 ohm at their specific frequencies as we expected. This is the extent of our testing. We do not guarantee this unit. As with all vintage electronics, you never know when an old component may fail. This unit is in good physical condition but dose have a couple good scratches on the top as seen in the pictures. We are very good at packing large and difficult items like this.

Vintage Sprague TO-6 Recently acquired at a Ham Swap meet. Unit powers up. Magic eye operates. I replaced a dead 6C4 tube. Controls need to be cleaned. Under side looks good. No evidence of past maintenance. The meter is not working. Will move with zero adjust. There is a crack on the plastic cover. Offered as is for parts/repair. May be a good donor for one you have or fix it up. Cosmetics are very good. These units are highly desired by tube radio/guitar amp repair men. USA sales only!
