Repair Roland RE-201 Space Echo Tape Delay Reparatur Service28. Dezember 2019
Roland JP 8080 with absolutely no output, not on the main L/R and also no sound via headphones. Like in the JP8000 I suggested a leaky electrolytic capacitor. I was right, but the difference, it was not just one but a few.
You may also noticed the dark spots on the front panel.
Sure enough I cleaned this and the Roland JP-8080 synthesizer looks and works (!) like new !
There are lethal voltage exposed in electronic devices. Unless you know what you are doing, don’t try this. If you following along, you doing so at your own risk.
I’m documenting repairs for my reference and yours.
