Also agree with Racamuti. Simple test to check for the proper polarity hook-up of your speakers. Disconnect the speaker cables from the Power Amp.Take a D cell battery and momentarily connect one speaker cable wire to the positive side of the batt...

Order of importance,Middle rowback rowfront rowRun the Amperex PQ tubes in the middle and the back row, Tesla in the front row. Try that and post back.I also recommend Herbie's HAL-O tube dampers.Install them near the top fat part of the tubes.. 
to ground or not to ground
My apartment has a circuit breaker in the breaker box but my audio is not grounded.Dazzdax, I am going to take a guess here. The receptacle your audio system is plugged into is an old 2 wire type, no equipment safety ground. If all your equipment ...
