Well, I cracked open the moog, got the 'board open... and realized
that I'm in way over my head with this one. Way, way over my head.

So now this is an appeal for either really, really good instructions
on how to check on the electrons goin' round in the moog - like how to
check the gate signal of the keyboard and the VCA, or an appeal for
someone who is knowledgable in micromoogs to offer to repair it.

I'd really feel much better sending this thing off to a synth tech,
but if someone could walk me through checking voltages and stuff, that
would be great.

Failing that, does anybody know of a synth tech that isn't swamped
with work this time of year that I could send this to?
