Discussion about the Korg PolySix synthesizer

Hi all,

I keep seeing messages posted regarding tuning etc. I can pretty much
promise you all that this is caused by the opto on the KLM366.
Within the last year I have repaired 5 pcb's all suffering from the
same problem, ie tuning C6 is ok but when you line up C2 to be at the
correct pitch , the octaves are not correct. I've also see units that
play an octave over 11 notes C2-B3, not enough range on the pots to
tune up just to name the common ones. From now I dont even bother
trying to tune a P6 without swapping the opto as you will most likely
be wasting yourtime. If you need a pdf copy of the service manual email
me at ibradshaw@btconnect.com also if you need any tips let me know.

I have really spent a lot of time last summer figuring how these units
tick and learnt just about everything I could. I've worked
professionally (if that's how you spell it!) repairing synths over the
last 18 years and specialise in Korg, Ensoniq, Kurzweil and Alesis

Is the "OPTO" you speak of the photocoupler? I'm having a little trouble
locating the replacement part. Do you have the NTE replacement number - or
where I could find one?

Also - what causes them to go bad? Could another cirucuit replace the opto?

Yes. I confirmed with him. I'm having a hard time trying to find the
replacement piece. I'd like to build an alternative circuit (espicially if
they're prone to failure) but I can't even find a datasheet on the thing.
Have you searched?
