Discussion about the Korg PolySix synthesizer

For the love of Pete. The distortion is still there. FWIW, it
actually sounds more like something osciallating at a high
frequency. I went through and checked the continuity of some more
traces and everything checked out okay. I jumped a couple of
suspicious traces.

My only thought now, at least in regards to what *I* can do next, is
to remove the jumps I put in over the past two days and start over
from there. IC30 seems to be okay based on what I could measure.

Of course, now the patch and bank buttons are going haywire.

Does anyone see anything in my descriptions that could help?

That sounds like what my P6 is doing too - like the mod wheel is fully on.
Everything is 'bubbling'. I have found that the PWM width control seems to
have the best effect on it, but also, if I leave the P6 switched on for an
hour or so, it goes away. I'm not an electronics-type, so I really don't
have a clue, but the fact that it goes away (usually) after a long warm-up
might mean something to some of you?

Yeah, it sounds more like the or *a* LFO gone haywire, but at a
frequency where it sounds more like distortion.

The only other conclusion I can come to is that I fried IC30 when
installing the new chip. The electronics store I go to didn't have
any 14 pin IC sockets. Maybe I'll stop by Radio Shack to see if they
do. That and the initial I repairs I made weren't robust enough or
didn't catch everything breaking down.

Fortunately I have five more 74LS08's left!

One thing I noticed while checking traces and other connections on
the board is that not all of the connections read the same value,
though they all fall within certain value groups, as it were. Would
anyone mind telling me what I should be seeing?

Also, can anyone tell me what R17 is? On the schem it's called "RKC
1/8 88 10k". What does it do? Can I get a new one readily?

The reason I ask is because I'm thinking about starting from scratch;
removing the jumps I made before; replacing ICs 30 & 31 and possibly
R17. Since I've had my Polysix and have seen pictures of others'
KLM367s it looks as though mine was/is in pretty rough shape. A lot
of the solder points above the battery area are dull, and some have
visibly corroded. I've checked them all, include a lot of what-are-
they-called? vias? (the areas where the path switches from the bottom
to the top and vice-versa) and all check out, but some look "bad."

Anyway, that's my story. I really prefer to be playing instead of
fixing, but nothing sounds like a *real* Polysix and thus I'm
addicted. Any input is appreciated.

if you trigger the lfo to frequency oscillation and adjust the lfo frequency to maximum, you will get also very heavy distorted sounds. and that sounds like the IC30/31 problem. but i discovered also other issues that effects the lfo. the cables from the board to the top the control board are very short. sometimes if i open my case they lost the contact and i get strange effects too

in the last month we are talking about an lfo issue that sounds like
a distortion. and voila, now i get the same problem. really strange.
if i adjust the phaser/chorus speed, i get strange sounds and i'm
unable to restore it back. and from this point its impossible to
disable the lfo level too. some sliders are doing really strange
things (sustain adjusts cutoff eg).
mmh so far it can't be the IC30/31 problem, since i already replaced
it. (and i changed it again, to check if something is damaged again)
did someone found a solution for this problem?

I was never able to figure out what the cause was. I went through
everything on that side of the board and couldn't find a bad
connection or failed component. Good luck!
