Discussion about the Korg PolySix synthesizer

This seems to be a popular topic, but once again: I Can't get the 
F***R to "tune". Ive done and redone the procedures in the Service 
manual, but it still only is in tune about one and a half octave in 
the middle. I would like to know if anyone has any hints on how to 
make this LOOONG episode shorter. As it is now all it does is lay 
there beautiful and entizing, but all I can use it for is Noice 
basically...

I've Changed the opto and the battery and all is well, no pots are 
defunkt. What to do, it to cool to just be a coffey-table...
