38) Repairing a 4,000 Volt Power Supply

Ol’ Sparky’s finally thrown the hatch. What should output 4kV is putting out -2v; I know, it’s a sad day indeed. But fear not as we will get it working again in this video… or will we? Along the journey I point out a few things that are typical failure modes in old test equipment and replace a bunch of rotten components from the era of bellbottoms with new-old-stock components from the bellbottom era. I wasn’t sure if I would release this video, but I had the camera rolling during most of the process so I strung it together just for kicks and maybe as a warning to those who dare venture into purchasing rickety old test equipment. Enjoy the show.
