[sdiy] Korg Polysix - now weirdness

[Karl Ekdahl]

Thanks all for your replies.

It turns out that the dude who "repaired" the polysix before me managed to install each and every diode in the scanning matrix backwards... ...wow...

Anyway it's supposeably "working" now but now i'm in tuning-hell. I managed to get all voices to tune up fairly well despite the service manuals pretty crappy description (by "Play C6 and adjust VR11 to 0Cent" they mean 4186hZ - right?) except for one voice that totally refuses. Basically there's no more "turn" on the low-tune pot and i cannot get it to work. Does it seem like my Oscillator #3 (that refuses to tune) is busted somehow to anyone but me?

Furthermore the service manual doesn't mention VR14 (D#4-E4 ADJ) or VR15 (tune mid). Also, the switch which is talked about on tuning step 1: "Change circuit board slide switch to opposite position (away from VR1)" doesn't seem to change anything, i'm guessing "away from VR1" means the back position, towards the rear. VR1, VR3 and VR15 also makes the pitch "slide" when i turn them, but i'm guessing that's normal. VR14 (D#4-E4 ADJ) doesn't seem to be affecting much of anything.

Arghhh  three hours just on trying to tune this @!@#$!@ thing...

Thanks

Karl
