Minikorg works suddenly on Sunday morning
My local PC tech replaced all the capacitors but to no avail...still droning sounds
So one Friday evening, I decided to clean the tuning pots with rubbing alcohol and cotton buds and tweaking them, making sure not to clean away the sharpie marker markings made by the factory. I made sure I set the pots back to original positions after the maxikorg lesson.
I switched on the minikorg this morning and cranked the switches and did some LFO with traveler...
Suddenly the headphones went soft and the keyboard started working. Clean and in tune notes...
My non-professional conclusion, the pots are dirty and old pots are preventing the current from VCO to the output..
Here is a clip of the sound test
Replacement of missing sliders with maxikorg sliders
The seller of my maxikorg recommended me to a ebay seller in Holland who restores vintage synth
He sold me several original replacement sliders and also a Maxikorg VCO.
