The Kawai & Teisco Analog Synths Group

Definitely sounds to me like the battery damage was not yet entirely
solved...

so far and where we where headed next!

be. Unfortunately I'm now unable to spend any more time on it and will
be looking to find a new home for it.

things wrong with it. The damage was caused by the leaking battery and
a few components have been replaced. I think the problem now lies in
the envelope area as each voice seems to have a different timbre and
envelope timing. A couple of voices don't even sound at all or are
very qiuet.

difficult to find SX-210 Service Manual which has full schematics of
all boards, calibration procedures, a parts list and specs of some
components used.
