As you face the amp, left is left and right is right. If you swap tubes, does the scratchiness move to the right ear? Does this happen with other tubes, as well?
I only notice it with the Mullard's. Once I past 30 minutes the scratchiness starts to get louder and louder. I even have 3 sets of 8083's. Same thing. The left tube or pot makes these sounds.Maybe it is that family and the voltage being a problem.
