I've recently acquired a Quadra 700 from eBay. The power supply seems to
be dead in the water; no voltage whatsoever on any of the lines, including
the +5v trickle. Before I go delving into finding what may be wrong with
the supply, does anyone happen to have a schematic for the GE version of
this power supply? There's one available from bomarc.org, but they only
deal with physical checks and mail, which means it would probably be about
a week before I got anything back.
Likewise, if anyone knows common failure modes for this particular supply
(the Astec one has a known failure in the +5v trickle with a known hackish
workaround, but the GE supply has a totally different reference designator
schema and possibly completely different circuitry), I'd be interested in
hearing about it.
