Repair Korg Poly 61 Vintage Analog Synthesizer Reparatur Service
Korg Poly 61. The battery was leaky and it needed MIDI installed. In this case the Tubbutec ModyPoly.
While neutralizing this battery corrosion with citric acid and distilled water I noticed some leaky capacitors on the cpu board. So I thought it might be a good idea to replace all electrolytic capacitors. If you don´t do this it will damage your synth, sooner or later. Here you can spot leaky capacitors on the panel board. While I had this apart I also cleaned the potentiometer.
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.
