Korg Poly-61M Project Machine

“This auction is for a KORG POLY-61M key synth vintage analog keyboard with MIDI “FOR PARTS”. I put it for parts because there is no sound coming out of it. The keyboard turns on. Every time you press a key it sounds like a tick. Every time you press a key the diodes on the board(508A) inside light up. I tried to find out what chip,diode,capacitor or resistors were bad but it was an impossible task for me because I don’t have the right equipment to test it. It seem like they spilled something on it. I took out the board(509A) and cleaned it out but to no avail. So I’m selling this AS-IS. From what I have been reading its a pretty simple fix. Please look at the pictures for more details and condition. Thanks and good luck.” Click here to search for synths on eBay
