Solid State 83 Kit for Tube Testers This is a Do It Yourself Kit for building an 83 rectifier replacement. I have built 100s of these and sold them 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. Comes with enough 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 in operation as high voltage is 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 August 2014 TV-7B/U by Dan Nelson. Here is how it compared to a glass 83: Test results Glass 83 SS83R 6V6GT 89 88 12AX7 44 & 42 44 & 42 01A 26 26 807 89 89 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 ealier (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.
