DIY Kit Solid State 83 Regulated Replacement Rectifier
This will work in any tube tester brand & or model that uses a glass type 83
This is a
Do It Yourself Kit
for building an 83 rectifier replacement. I have built 100s of these that have 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 60/40 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-7B/U by Dan Nelson. Here is how it compared to a glass 83:

This 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.

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 1/4 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 KT88`s with the fuse lamp barely lighting. Before, they both lit up my Hickok's like a street lamp!!!! I`m sure I`ll be a repeat customer in the future!!!
thanks, Alan
