"The Yamaha DX1 is a flagship synthesizer from 1984, top of the line of the DX series. Since their production in 1984 there were only 140 of them made in the world. Weighing at about a 100 lbs with 73 full length wooden keys and a wooden case it offers 32 note polyphony and supersonic performances thanks to the carefully selected components. Uniquely for a vintage synthesizer it features polyphonic aftertouch. Yamaha built these to impress, not to a price point (they originally retailed at about $10,000 in 1984-around $35,000 in today’s money).

Completely overhauled by a professional technician it is functioning at 100% capacity. The only cosmetic blemish is it is missing one voice cap(#8 shown in picture) but that voice button still works when pressed.
All key bed contacts have been completely cleaned and keys aligned. Power supply recap and adjusted. Memory battery replaced with new one. Cleaned and lubricated front panel sliders. Light front panel cleaned up."
