ROLAND JUPITER 6 DEMO

Here is a full demo on the Roland Jupiter 6 Polyphonic synthesizer. This unit belongs to Thane Evans, and it over-went a pretty major surgery to get it back to good health. History on the Jupiter 6: Work done on this Jupiter 6: -Main issues found were CPU locking up/causing intermittent failures when doing normal operations (moving sliders/random glitchy lights) -Unit wouldn't accept the Cassette factory presets wav file upload, and would cause unit to crash/freeze. -Battery Replacement + Socket -Replaced Corrupt RAM chip (TC5517APL) -Replaced heavily corroded/faulty Slide Potentiometers/Pots on both Panel boards. Unit feels great now and doesn't jump around the values causing lockups on the CPU. -Replaced electrolytic capacitors that were out of spec/leaking on both voice boards. (x71 total throughout entire synth) -Rebuilt Power Supply, hit cold solder joints on connectors and voltage regulators, through out entire synth -Full Calibration to factory specs, tuning and D/A calibrations -Upgraded Firmware to latest V6 firmware (previous firmware/eprom was V2) -Burned 2732A Eprom and installed factory presets -Hit cold/cracked solder joints throughout all connectors for better reliability in future -Burned in unit for 48 hours, tested all functions-sounds great now!
