Lift the ground that is from the tone arm away from the chassis ground on the phono pre-amp. You could have the classic ground loop problem. If this does cure the problem then look for a leaky cap.
Popping noise when muting pream
I have a VTL preamp hooked up to a sonic frontiers sfs 50 amp using all nordost cables. I noticed a hum in the right channel and when I mute the preamp it pops.
I've checked all the tubes and they are seated fine, I also checked my cables and they are also seated.
My equipment is plugged into a Panamax power conditioner. Suggestions?
