Discussion about the Korg PolySix synthesizer

After years of procrastinating, I spent this past weekend creating
schematic and PCB files for the KLM-367A.  It has gotten to the point
where it takes less time to assemble a new board than to repair a damaged
one.  Thus, I will be offering new replacement boards in the very near
future.  Here is an image of the layout:

  Notice the 3V CR2032-type coin cell socket that replaces the evil, old 
NiCad battery. ;)

  I known this for a long time, but I might remark that the Polysix
service manual's KLM-367 schematic has a few errors.  My schematic is
"correct" as it is derived from the manual's schematic but cross-checked
against the actual board layout.  The result is the exact same circuit as
is implemented on original KLM-367s.

  Once I build and test a few of these boards, I'll make a few revisions
to better support adding in Ricard Wolf's MIDI retrofit as well as the
little bit of hardware needed to support adding in my "2nd VCO PCB" which
provides 2 VCOs per voice similar to the Trident.
