“I am the original owner of this Jupiter 8 since I bought it new in 1982. For 4 years, regular road use. Got a few small dents in the top panel by the back. After that, it was only in my studio. In 1994, I added a MIDI retrofit kit, which works great. Eventually, the power switch broke, and I couldn’t find a factory replacement. The Jupiter sat unused for 20 years. Finally, I turned it over to master electronic engineer, synth builder (and actual Rocket Scientist) Dave Hamara, who replaced the power supply and switch with a modern switch with removable cable. He also replaced every single capacitor in the entire unit, replaced the battery, reloaded the factory sounds, and completely calibrated the unit to factory specs. This comes with the MIDI retrofit user guide, and the service manual with calibration specs, as shown.
All synth functions, every knob and button is 100% tested and working perfectly. It breaks my heart to sell this, I’ve had it more than half my life. Please take good care of it, and make cool music. ”
