Archive of the former Yahoo!Groups mailing list: Discussion about the Korg PolySix synthesizer

I finally had the chance to start taking apart my PolySix. It needs
a good cleaning on the inside, and I find a 4 of Diamonds playing
card underneath one of the PC boards.

The KLM-367 board has prior to been worked on. Underneath there are
some wires patched into IC-31. I don't think whomever did the work
cleaned the PC board too well as a lot of the solder points on the
top of the board in the area above the battery all the way up to the
connectors suffer from corrosion. This board is beyond my ability to
repair; I am neither knowledgable enough or disciplined enough to do
it. I would consider myself an artist who can maintain his gear
rather than a technician with an affinity for music and/or
synthesizers.

Many questions have I:

Should the pitch bend wheel have springs? I noticed it wasn't
springing back when I first got it, but I didn't think much of it
figuring the springs were unhooked or stretched or something. If it
should have springs, can anyone recommend a replacement? If it came
from the factory spring-less, has anyone tried adding springs?

I'm far from wealthy, I'm hardly even middle class, so my resources
are rather limited. I want the PolySix to come alive, however once
it's alive I want to be as certain as possible I won't have to invest
more money into it for many years. The question is, will replacing
KLM-367 fix the other significant problems it has: waveform selector
not working, the two patch buttons and two program buttons always
staying lit?

I'm not asking anyone to make decisions for me here, it would simply
be very helpful to have some insight on the KLM-367 matter so I know
where I'm at. To be quite honest, I'm now trying to decide whether I
invest money in it now, or cut my losses and sell it as is (and,
unfortunately, another synth) and get something more reliable like a
Juno. For what I'm doing musically, I need the knobs (or sliders).

So, please, any thoughts would be helpful.
