“This circa 1986-88 (?) DX11 powers up, but sounds like it needs work. None of the presets produce proper sound; a high-pitched digital squeal is heard in some cases, other cases no output at all. Garbled characters appear on the LED for certain button or preset selections. Repair or harvest for its very valuable parts.
Cosmetically it’s in good to very good condition. No keys appear broken, frame seems solid without cracks, just minor wear and tear.” Click here to search for synths on eBay
