“I’m selling my fully Working Yamaha DX100 to fund an analogue sequencer. It’s in good condition for a 30+ year old synth with a few very minor scratches, however it does have a repaired Key, the bottom C which has been glued. See Pictures. This repair has lasted years and has not affected its operation at all. All keys play well and the LCD contrast is good with no missing pixels. The symth comes with both manuals (slightly tatty) and non Yamaha power supply.” Click here to visit listing on eBay

“This synth is in working condition and includes the original power supply. The only flaw I’m aware of is cosmetic damage to one key which seems to have been cracked and repaired. It was like this when I got it and doesn’t effect the playability at all. There’s a close up in the photos.”

“This DX-100 is as clean a unit as you’ll find. Everything works perfectly and there is very little wear and tear on it that’s really visible in person. The photos accentuate it more than you would really see in person. The face and sides of the unit are clean. It looks pretty close to the way it did brand new. It has spent most of its life in a dust free studio inside an old Pu leather Realistic bag (included). The bag is well worn but it has kept the keyboard pretty pristine.

Also included is the original power supply, the original cassette of patches from the factory and a publicity flyer from the era.. sorry, I don’t have the manual but it can be found online.”

“I purchased this DX100 new in 1985 with every intention of becoming the next Rick Wakeman or Keith Emerson until I discovered I was too lazy to practice and resorted instead to making sound effects for my answering machine messages. Shortly after, it took up residency in my bedroom closet where it remained until now nearly 40 years later. It is in near new condition with every function working and no noise from the pots once I sprayed them with contact cleaner. It was never stored with batteries installed and has been kept in a non-smoking environment. AC Power supply is included.” Click here to visit listing on eBay

“Synth is boxed and in great condition given the age of it. Had initially tracked one down for my son who plays piano, but he seems to be exclusively using his computer to compose, so this item has been cupboard bound for the last 9 months or so. Runs on batteries and mains power, although i will remove the batteries before delivery for safety purposes.” Click here to visit listing on eBay
