“Yamaha DX100- Vintage Programmable Algorithm Synthesizer.
Its in great condition. All keys work EXCEPT for one, the far right key (last pic). It’s not loose or broken, it’s just not responsive and makes no sound when pressed.
Other than that one key, everything functions as it should with no problems; 1/4 jack inputs, headphones jack, volume slider & jog wheels, etc. It has both strap bolts and battery cover in tact. Power adapter is included.” Click here to visit listing on eBay
