There was always some hum on my moog but when played the synth was loud enough to cover this. but now the general volume of the soundoutput has fallen to be nearly at the same level as the humming. There is also some kind of crackling and clicking sound that occours from time to time, but very unregulary.
the service manual mentions this problem and it recommends to replace the rectifiers (diodes) the power-regulators. but it mentions the humming only together with a wild modulation of all signals, which is not the problem... the synth itself is fine, all funktions are ok so far.
I was thinking of replacing the powertransformer (the light of the power swith is always slightly flickering) and the two big elko-condensers, they are nearly 40 years old now...
somebody has a better idea or a hint.
in the moment I check for loose connections...
thanks in advance *niki

Hi

I should think you would not need to replace the transformer. Probably all you need to do is replace the two capacitors. Indeed, 40 year old electrolytics have probably seen better days.
