How to repair and make as new a vintage synthesizer

It makes sense to change all electrolytic and tantalum capacitors which have a limited life.


Examples:


An Oberheim DMX was dead. After changing the tantalum capacitor that was connected to a start control pin of the CPU it came to life.


An EKOsynth could not get to 440Hz. After some electrolytic capacitors were changed it did. After all electrolytic capacitors were replaced the filter envelope attack control was still not responding. After the only 2 tantalum capacitors were replaced it come fantastically back.
