Moog Source noise issue

Hello

Maybe someone can help me suss out a little issue with a Moog Source. There is a bit of noise coming from it’s output, it sounds very much like wind on a microphone. Just little bursts of noise. It’s happening regularly but with no discernible pattern. Just a stream of these little noise bursts constantly coming from the source. It’s quieter than the actual signal output, which seems pretty normal, but still distracting.

Maybe this is an obvious behavior of an aging part? I suspect something of that sort. Otherwise it’s a lovely synth. I suspect I’ll have to bring it to a tech, but any input about this most welcome.

Probably some filtering capacitors (in the PSU section) or decoupling caps (in the digital part of the synth) that aren’t aging gracefully…

It’s got to be something of that sort.
