Need a quality solid-state #83 upgrade?
We offer a premium version of the #83 solid-state upgrade that is fused to protect your transformer. Yes, solid-state diodes are reliable but they are known to short occasionally, and you will be happy that you bought our fused #83 solid-state upgrade instead of a cheapass unfused module that can damage or destroy your transformer when its diodes short someday. I have personally seen several instances of the cheap auction-sold SS83 upgrade modules that have shorted out and damaged or ruined the tube tester transformer. It happens, but you can take steps to better protect your tester! Don’t expect a fuse on the transformer primary will adequately protect you against this problem — it will not. Price $18 free ship USA.
