Re: SC502 Old Enough to Smoke?
That's certainly where I'd look. I'd look at all of the supplies that get their reference from the +20. If that's on, then the problems go with the individual supplies.toggle quoted messageShow quoted text
One of the most common problems, as you know, are shorted or leaky tantalums.

Well I checked the onboard power regulators and the -20V is at -20.46, the +20V is at +16.64v and the +5V is at +4.25. Since the +5 supply gets its reference from the +20v supply I suppose I'll be looking at what's connected to the +20 rail first.
