Roland Alpha Juno 2 Vintage Analog Synthesizer. 3 keys weren’t working. 2 dead silent, 1 too loud. This was caused by a broken contact strip which I replaced with a used one from a parts machine. I also cleaned the whole keypad.
4 tactile were bad, I replaced them. I also recapped the psu, changed the battery (with new holder). I cleaned the rotary, potentiometer and slider. I gave everything a good wash 😉
I’m documenting repairs for my reference and yours.
