RE: FCUPS versions, other info

If its just the negative bias supply that's buggered up I can make do. My transformer has a 50V tap.

The C- output appears to be derived from a neg. FW rectifier (2 diodes in series), then a zener/emitter-follower, with those 2 10uF 630V film caps between each stage. So, if I can just desolder those rectifier diodes I should be okay, correct?

Hopefully, I didn't fry any other bits. It did appear to be giving stable B+ supply.
