Not sure whether this thread would still be seen. I have the same issue and if I mute the unit, the hum/hiss/buzz goes away. It is more of a static sound. I am going to try to take the tubes out and clean the socket with deoxit and see if that solves it.
Audible Illusions Tube Pre-Amp Hum- Help Diagnosing
Began getting a low-level hum from the pre-amp which stays at the same low volume no matter where volume pots are set. Both channels are affected, although it seems to have begun in one channel (or maybe it had been more noticable in one channel, or maybe it was my imagination.)
Is this a tube thing, a ground thing, or some other issue?
Would like to narrow down possibilities before tearing apart the installation and/or buying tubes or other things unnecessarily.
Thanks in advance for any guidance.
