I'm working on a power supply that has four old big honkin' capacitors,
two 10,000uF 25V and two 95,000uF 15V electrolytics, dating from 1977.
The question is, should I repair them (reconditioning with a variac... or
lightbulbs in series, since I don't have a variac :) or should I just
consider them most likely lost to time and attempt to replace them with
more modern parts? The power supply is otherwise fine, and in fact on a
whim, I was able to power it up and get steady power from it, no hint of
a problem. I just worry about the poor caps after being off for so long.
Opinions?
