I finally brought the pair upstairs late yesterday afternoon, and hooked them up noticing the slight hum from the speakers without any source going through them. No problem since that seems to be the norm. I wasn't able to listen long due dinner, tired, family stuff, etc... maybe an hour, so I went to power down the amps first.
I reached and switched both amps off at the same time, and 2nd amp maybe a high screech sound that seemed to get louder, then fade as the power dissipated. This morning I thought I'd have a second go, and when I went to power on the amps, amp No. 1 came on fine while the amp No. 2 came on with no problems then the screeching began.
I went down stairs to take some readings and found everything to be somewhat OK. Readings from B2 and B3 were ~208 instead of 185 and 188. I went and switched the 12AT7 with another good tube, and the readings were close to the same. I took the amp back upstairs from the basement and hooked everything up, powered the amp back on, and the screech was still there.
I swamped 2A3's and had the same result. Now, during construction of the 2nd amp, the bolt that came loose on the powersupply that has the solder tab. Check out this link called Powersupply Bolt.
Should I replace that bolt, or is there something else the matter? I can provide any other information that's needed, just please tell me what it is in simple terms cause I'm not as knowledgeable as most here. Thanks to all who may reply.
