Discussion about the Korg PolySix synthesizer

Looks like the cut was to separate some circuitry from +5V on the control board.   Then on my unit a separate blue wire was run from the power supply to bring +5V to that circuitry.  This may have been done for noise reasons.

Happy 2014 to all.

While continuing to investigate my malfunctioning Polysix, I inspected the leftmost control board, the one which has a blue connector soldered to the power supply.

If you follow that trace, you may find a break in the line somewhere as I did. A break was also found in the same board of the spare Polysix (now being parted), and also from the Polysix of a member on French forum anafrog.

I repaired both boards.
