Working, calibrated "by the book", following the original military maintenance manual instructions (calibration report sheets included).Calibration spot checked against "bogey" tubes from Blueglow Electronics (checked within 1.6, 2.4 and 6.8 using 12AT7, 6L6 and6AU6 bogey tubes, respectively ... no attempt to fine tune calibration for exact match to all bogeys).All tube sockets except the two short-lead subminiature sockets were checked by testing at least one tube successfully in each socket (i...ncluding the acorn tube socket type 954 and the long-lead subminiature socket adapter type 5678).Includes all relevant manuals (of which I am aware) in PDF format on a USB flash drive.All switches, pots rheostats and pushbuttons work smoothly, and appear to be functioning properly, though I have not exhaustively checked every possible operating position and combination.Cosmetic condition is typical ex-military: some paint loss, scrapes, case dings, etc. (see photo).In addition to the description above, I am aware of the following issues: There is no carrying handle attached to the case, though the brackets for the handle are securely attached. The recessed rubber sealing gasket around the perimeter of the lid is badly deteriorated (hardened cracked), though the channel is in good condition to accept a new gasket if you care to replace it. The two specialized tube adapters (for types 2C39, 3E29, 829-B, etc.) are missing along with the brackets for securing them. One of the two leads for connecting to tube top caps (the black one) is missing. The red one, which is included, is a modern reproduction, not the original. As the two leads are interchangeable, there should be no problem, except for testing those very few tubes with more than one cap.The bracket for winding up the power cord in the lid is missing.The pin straighteners for 7 and 9-pin miniature tubes is an after-market Hytron double-sided "hockey puck" type, not the original.The 7-pin miniature tube socket is quite worn, though I had no problems using it. Just to be sure, I am including a Vector octal-to-7-pin mini adapter (I couldn't find a "socket saver" to install in the 7-pin mini socket).The meter mechanical zero is very slightly off (maybe 13 of one minor scale division high ... see photo).The Tube Testing Data booklet is in poor condition. There is a much better copy among the included PDF files, plus a copy of Nolan "Redneck" Lee's well-regarded Excel file.This particular tester seems to require more warm-up time than most, especially in my somewhat damp basement shop. If you just flip it on and immediately go about testing tubes, you will likely see false indications of SHORTS and GAS. After 10 minutes or so, the false SHORTS go away, but the GAS reading may need as much as a half hour to fully stabilize. The Gm readings seem to be pretty much right on almost immediately.
VINTAGE 1962 U.S.ARMY MILITARY TEST SET ELECTRON TV-7U TUBE TESTER WORKS This came out of an Audiophile, Ham Radio Collector's collection Many of the items were still connected hooked up.His collection was in great condition.We have alot of items for sale. In good cosmetic condition Sold as is .
US ARMY Technical Course Lesson teaches how to use the US MilitaryHickok TV-7U Tube Tester CheckerPAPER course lesson, professional Spiral Bound. All pages 600 dpi scanned, cleaned up with photoshop, and newly laser printed. For all variations of TV-7 (such as TV-7A, TV-7D, etc...)US Military Course Lesson on using the vintage TV-7, TV-7U tube tester. Teaches the control functions, explains the data book, and gives detailed examples of PROPER testing of several different tubes. You would be surp...rised how many people really do not TOTALLY understand how to use a TV-7 tester. (They THINK they do....) Straightforward information as you would expect for the US Military -- No nonsense.INCLUDES Gm conversion table so that you can easily convert the TV-7 meter reading into actual Micromhos score.Again, this is a US Military Course Lesson to teach proper usage of the TV-7U this is not a tube setup chart, roll chart, service manual, or schematic.
Ok so when I 1st listed this it seemed to work I tested a few tubes and compared to my other Hickok tester and they matched then someone said something about the red suspect markings well I brought this to my radio guy and he said they were for some wires that he did not have but when doing so he tested some other tubes and he thinks there is a short in the tester because some tubes were not showing anything on the gauge so this is being sold as is

This comes with a 30-day hassle free return policy.Free USA Shipping on this itemRegulated Solid State 83 Kit for Tube TestersThis is a Do It Yourself Kit for building an 83 rectifier replacement. I have built 100s of these that hav...e sold on eBay. They have been used in all types of tube testers with 100 positive feedback. You will not find a better 83 replacement anywhere. You will need a 25-watt soldering iron and wire cutters and enough 6040 rosin core solder to get the job done. After you build it, test it as an 83 in your tube tester to be sure it works right. To avoid electrical shock, Do not touch the circuit board while testing or while in operation as high voltages are present.As type 83 mercury vapor tubes are getting scarce expensive, the need for a good solid state replacement was becoming apparent. This replacement kit contains 2 diodes, 2 Zener diodes for regulation and proper voltage drop, 2 resistors, a circuit board, and 4 pin base that when built emulates a glass type 83.I did a series of tests on my newly rebuilt and calibrated in October 2018 TV-7BU by Dan Nelson. Here is how it compared to a glass 83:Test results Glass 83 SS83R6V6GT 89 8812AX7 44 42 44 4201A 26 26807 89 89This test was also done on a Hickok 800A with repeatable results. No calibration was needed to get correct test results on either tester. The only adjustment done to the testers was a slight line control setting.Other SS replacements I have tried that were made way back in the 1970s or earlier (1N2634) often made correct line adjust impossible and test results were way off because of improper voltage drop.I often forget to turn off my tester so it can run overnight and as the 83 tube wears out, the calibration on the tester changes. The SS83R ( solid state 83 regulated) does not wear out.Less power draw and way less heat on tester transformer and other parts so longer tester life before recalibration. Pictures tell the rest of the story and are part of the cosmetic description so please take a close LOOK.at them. WYSIWYGPlease ask any questions before you bid to avoid any communication problems or disappointments.Your purchase will be carefully Packed and Promptly Shipped to your confirmed PayPal address..How to fuse protect your tester. I get questions about fusing the solid state rectifiers just in case a diode shorts out. It is not a bad idea but in all the SS83R replacement rectifiers I have sold over the years, I have yet to have one go bad. I do have the tester I use for testing the SS83R fused but again have never had a fuse blow. I put 14 amp fuse rated for 600 volts in line with the plate wires on the 83 tube socket. This gives me up to 250ma plate current draw protection.Comments from a happy customer:EXCELLENT solid state 83 kit 14.6 watts less draw on my R.D. 1575b Hickok and 15.2 Watts less draw on my 538a Hickok..unchanged calibration on both of my testers...I can even test KT88s with the fuse lamp barely lighting. Before, they both lit up my Hickok's like a street lamp Im sure Ill be a repeat customer in the futurebr style"color: rgb(35, 31, 32) font-family: Helvetica, Arial, sans-serif font-size: 14px background-color: rgb(249, 249, 249)"thanks, AlanWhy Buy From Elderly Electronics:We are experienced sellers on eBay since 1999.
