Regulated Solid State 83 for Tube Testers<br>As type 83 mercury vapor tubes are getting scarce & expensive, the need for a good solid state replacement was becoming apparent. This replacement contains 2 diodes, 2 Zener diodes for regulation and proper voltage drop and 2 resistors that when combined emulate a glass type 83. It is built on a circuit board and placed in a new 4 pin tube base. It was then checked to ensure a balance between both sides and strong emissions. This will work in any tube tester that uses a glass 83 rectifier. I have sold hundreds of these with 100% positive feedback.<br>You will not find a better 83 replacement anywhere.<br>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:<br>Test results<br>Glass 83<br>SS83R<br>6V6GT<br>89<br>88<br>12AX7<br>44 & 42<br>44 & 42<br>01A<br>26<br>26<br>807<br>89<br>89<br>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 very<br>slight<br>line control setting.<br>Other SS replacements I have tried that were made way back in the 1970s (1N2634) often made correct line adjust impossible and test results were way off because of improper voltage drop.<br>I sometimes forget to turn off my tester so it can run overnight and as<br>the 83 tube wears out, the calibration on the tester changes. The SS83R ( solid state 83 regulated) does not wear out.<br>Less power draw and way less heat on tester transformer and other parts so longer tester life before recalibration.<br>Pictures tell the rest of the story and are part of the cosmetic description so please take a close LOOK.at them.

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.<br>The pictures tell the rest of the story and are part of the cosmetic description so please take a close look at them.

Before, they both lit up my Hickoks like a street lamp!!!! I`m sure I`ll be a repeat customer in the future!!!<br>thanks, Alan<br>Why Buy From Elderly Electronics:<br>We know you have thousands of choices when it comes to purchasing vintage electronics on eBay.
