Death of a Serge

[Jim Johnson]

Wel, bad news... 

.. late last week my Serge stopped making sound.. so yesterday I popped it
out of the case, powered it up.. only to see smoke start pouring out of a
capacitor!

Now I'm trying to decide what to do. Obviously I will test the power
supply, but I doubt that the new Power One supply I put in is bad. Seems
more likely that the cap itself failed, and is shorting the supply.. though
there may be more wrong.

I realize that schematics of this are closely held secrets, that repair can
only be done by one man, and that he is currently on some extended
life-examining pilgrimage in the Upper Midwest. However, maybe somebody out
there who has puzzled through these things in the past can help me. The cap
in question is a ceramic disk on the Variable Q VCF board, about halfway
down, between a 100K trimpot and am LM3080. It's right next to the +15v
line, so I bet it is a decoupling cap. Can anyone confirm this?

TIA.. please ...
