I'm currently having rather annoying problem with my phono set up that I hope someone might be able to help me with... A single 'pop' is emitted through the speakers every 20 minutes or so. Loudness is dependent on the amp volume setting. It sounds like the release of static build up but I’m not sure if it is, or indeed, the cause. A dodgy cap maybe? I'm pretty sure I’ve isolated it to the phono amp as it only happens when both amps are actively playing music or indeed, on idle with the TT off. It doesn't occur when I switch the power amp (valve based 300b) to my digital source so it can't be a tube issue. (I've also checked the various cables) The phono amp is a Valab LCR. Any tips that might help me locate the problem would be appreciated.
