” PPG WAVE 2.3 Synthesizer Keyboard – for restoration. Sold AS-IS. I know nothing about these. I did plug it in and it powers on. Sometimes 3 red light came on and after I pushed a few buttons to try to scroll it would only show black blocks on LED screen (see photos) I could never get it to change on LED screen. All the keys spring back up. There are some uneven keys (see photo) It has scratches. The silver plate that holds circuit boards straight was loose so I put some black tape on edge to hold circuit boards. (see last photo) I do not know the history of this keyboard. Absolutely no returns on this one. Sold as-is for restoring.” Click here to visit listing on eBay
