Hi Crow....

I'm restoring a Gentle Electric GE-101 pitch to voltage converter. Resurection

is a better word, since I bought it 'as-is' and that was apparently AFTER
someone
reversed the power supply at some time (and blew about every IC in the
thing)...

I have one board up and running, but the second board with the POTTED MODULE
is dead. So I have to figure out the 2.5" x 2.5" x 1/2" black epoxy coated
"slab o' fun"

I have (with a chisel) uncovered the PCB with little enough damage to trace
the
board.  Three opamps (looks like) and some discretes.  I hope the Carl Fravel
was
not a REAL dick, and did not fly any components up in the epoxy. :^P   I don't
think that
is the case.

Module has five pins, +/- supply, ground, input, output. Should be a
"fundamental
extractor"  but other than that I have no clue yet as to the technique.

So (Crow)... what should I use to melt the epoxy. You HAVE been there before,
haven't
you :^P
