Thanks, that's what I thought but I read I would hear it when music was playing also. I replaced the stock tubes with some NOS ones right after I bought it.
I'll try that. I'll have to do it at the end of the week. I'll try the stock ones also.
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.
