Inside a Roland Jupiter-4



via Abertronix on Facebook

"Inside of a Roland Jupiter 4. An old but beautiful 4 voice analog synthesizer. Its old so I need to replace most electrolytic capacitors and various other components...

The biggest worry with the Jupiter 4 is that it uses a rechargeable nicad battery to save your settings. The problem is that old batteries have a tendency to leak acid which eats away the copper traces in the circuit. Not impossible to fix but a pain. Im crossing my fingers with this one."
