Was just curious if anyone had any idea what might be causing it or if its normal.
Under any normal use I haven’t encountered this problem, but if I accidentally turn the preamp off and turn it right back on, there is a loud buzzing emitted from the pre itself (not speakers) from the moment it starts warmup, and then once its warmed up the sound with continue until I turn the pre off for a bit and power it back on. As long as I wait like 30-60 sec before I turn it on after powering it down its fine though. It also only seems to be from the right tube, but I could be wrong.
I mostly just wanna make sure it’s not gonna cause any sort of damage to the pre or tubes.
