Thanks, Jerry
I have a 990 hardware manual here that I haven't scanned in yet. It's
in storage right now, I don't have a scanner set up at the moment, and
I can't remember off-hand whether it has /12 schematics, but it's
monstrous and has lots of schematic foldouts. I'll see if I can find it
this weekend and let you know about the latter. I would think, though,
that the PSU is covered. The A13 chassis was used in other 990's. I
have a /10 setup in one. Been decades since it was powered up, though.
later,
