“Korg Poly 61 Polyphonic Synthesizer Fully Working With MIDI & CPU Board Upgrade
This is a 1981 Korg Poly 61 Polyphonic analogue synthesizer. This item is fully working with some upgrades. The unit has a brand new CPU board known as the cKLM-509A. This is a brand new, high quality, exact clone board of the old CPU board which was prone to failure. The other upgrade is added MIDI-IN function. You can noticed the daughter board on the last image and the MIDI-IN socket on the back. This synthesizer didn’t come with MIDI when it was first made. All key contacts have been cleaned and recoated. All keys and functions work. The exterior does have some blemishes please see images.
The only fault is the joystick. The joystick function works but in the up-down direction gets kind of stuck. Not sure if it needs lubrication. Also comes with a printed owner’s manual.” Click here to visit listing on eBay
