[sdiy] Non-DIY, but looking for repair advice...

Also, it's definitely been modified for US power - someone helpfully
pasted a hand-drawn diagram to the bottom of the interior XD Looks like
it's the same regulator board diagrammed in the service manual, plus a
tweak to the power-cord inlet to ground a three-prong outlet to the
case, but I'm no expert on this stuff. I can take a photo if need be,
but I'll check the PSU output first...
