Discussion about the Korg PolySix synthesizer

Typically the opto-resistor on the 366 is the cause of this scaling problem
when tuning. There is a file on the yahoo group site that has the following
email copied into it:

"I wanted to let you know that I've finally managed to repair my Precious
(Polysix). It was indeed the opto resistor, the PC-1, that was faulty. It
was suggested to me that I replace the old mysterious PC-1 component with a
VTL5C3 and change R93 from 4k7 to 1k2 (to get the VTL5C3 working properly)."

This worked for me too.
