I switched power tube places and hum stayed on left (nothing on right). I rolled another input tube I have and no change. The rectifier, a 5U4G is probably responsible correct?
No input (RCA only on the Supernaut) is plugged in to the amp, only AC power...forgot to mention a bit of microphonics on the left side only as well
I had the hum on one channel when I had it while using efficient headphones. However, I'm old school and tend not to care about stuff like that.
Ok, I have another rectifier on order so we will see if that's the source in 2 days or so. I will just listen in the mean time ;)
