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

Okay, so I've got the KLM-367A board all out of my Polysix. The battery
was gone from the thing when I got it. There is big time damage to the
solder tracings... it looks like IC30, 31, and 25 are fucked too. All
of their pins are either oxidized or have that red battery acid-ified look.
The solder tracings are spattered with corrosion all the way over to
the big IC22. So do you think my Polysix is screwed?

When I plug it in and play, I hear sound. The cutoff and res work,
the arp works, but all I hear when I play the keys is what sounds like
cross-modulation of the oscs. Maybe mixed with a little white noise.
I have set every knob to what should be a normal synth sound, but
no go. I've tried different patch numbers too.

So my dilemma is, is this worth my time to fix? Or should I just
salvage the good ICs and knobs for my Mono/poly (should it break
in the future), and try to incorporate the FX board into my Fatman?

I was really psyched to fix it, but since it looks like it's going to be
more than just fixing solder traces, I don't know if I'm up for it...
