Hello,
I have an old school Bertran Model 205A-03R High Voltage Power Supply. I had the voltage at like -400V and switched the polarity without setting the voltage to 0. Now it's giving me no voltage. Is it fried? I opened it up and the components look fine, but I'm getting no voltage or current readings. Does anyone have any experience with this? Could someone at least send me to a forum where old school high voltage power supplies are repaired?
Here's what it looks like:
