As others have noted above, replacing caps in the audio signal path can affect the the sound and character of the instrument so that's up to you. Personally, I replace ALL electrolytic caps and I've only ever noticed an improvement in audio quality and noise levels after doing this. Replacing the electrolytic caps in an ageing PSU is the first thing you should do in any restoration project IMO.
Thanks for the info.
I already know all this, and years ago when my Chroma didn`t work any more properly the first my former tech advised me was, to do a complete cap Job at first, and my very first question after was if there would be any risk of sound changing, but he denied immediately.
So I let him do the Job and the Chroma still sounded as "dusty" and "dirty" like before.
But once he told me as for the Minimoog, and I cannot reproduce what he told me as I`m no tech, people complained about the sound after having done the cap job on the PSU.
So he never did and with a great exception in comparison to all other vintage synths he still rejects doing any alterations on any Mini`s PSU, even NOT replacing it in total.
So that`s all I can tell about.
