Beware the massive voltage drop on LED lamps. Once I removed the lamp I could get enough current thru the auto transformer to power the analyzer. Everything was okayyy. The transformer was making a terrible buzz. Could be water, I hope not arcing. A capacitor failure on A20 ends testing early. A ceramic or whatever this thing is. It’s vintage, bulbous and orange. Part 10-20 and has a line with +++ denoting polo rigatoni I guess. I need to unhook the 5 volt 60 Amp rail so I don’t overvolt the logic and can verify this honkin power supply. 420 WATTS! Including the 2 aux units.
