It sounds like one of the tubes is microphonic. Try tapping on each tube and see if you hear the noise!
Noise through speakers when I tap the Source Switch.
I have a Unison Primo, only a few years old. I just noticed that when I tap the
knob to select source I can hear it through my speakers. Could there be a problem
with something? It's a hybrid, tube pre. Other that that it's quiet.
Thanks for any help.
