After realizing how indispensable a good HV supply is when working on or testing gear, I found this fella on Ebay. Tests out good but I might replace the electrolytic caps. It looks like they were done previously but it won’t hurt to get the latest in there.
The main need was to work on the oscillator for the Gates BC-1T outside of the chassis. It was a pain in the butt to keep making a mod and then put it back in. With this, I can keep it on the bench, optimize the circuitry, then put it in it’s final home once and for all.
