Thanks in advance for any insight you'all can provide me. I think the title of the thread sorta of says it all. Essentially, I built an all Octal guitar amp, base on a Super Reverb but without vibrato. The amp itself really sounds spectacular, but there is this issue when adjusting the volume. I can't help but think that it has to do with the number of Triode Stages being used. Could it be a phase or cross over distortion issue? The symptom is negated as the volume is increased (hum starts to decreases at the arbitrary "3" position of the volume control), but returns once the volume control resistance level is increased further. (Hum returns at the arbitrary "7" position on the volume control.)
Again thanks in advance for any thoughts and ideas.
