Archive of the former Yahoo!Groups mailing list: Discussion about the Korg PolySix synthesizer

Hello,
I recently acquired a polysix in rough shape. I tested out the battery board and the new connections for the corroded tracks seem to be all good. I have not installed the new battery yet but tested it out.
The arp functions along with the rate knob, the keys function but need all contacts cleaned badly. The control knobs do not effect sound at all except for the Attack which only functions rarely. The connectors leading from the battery board to the controls are good. The Mod wheel functions properly along with the bend and tune. Is there an obvious area to look at regarding this issue? Thanks for any input.
Best,
Eric
