[QUOTE="Mars, post: 151454, member: 817"] I had some feedback from the customer. He started the amp in triode mode, and she sang! Bass was full through his Full range drivers. The sound seems to be up to par. He did mention though that there is a perceivable hum coming from the amp and the loudspeakers. I am quite confident that nothing is busy self destructing, but that larger iron in the power supply is probably called for. Or maybe I should get the power transformer glued together more solidly that just waxing it. A temporary remedy would be to explore the 6V6GT as a possible output tube that might harmonize better with the current power supply design. An other option would be to see how the EL34 fare if the higher voltages of 380V are used. More to follow. [/QUOTE]
