ROLAND JUPITER 6 DEMO
video upload by Synth Tailor Electronics
"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!"
