[QUOTE="GuitarGuyLP, post: 107585, member: 1848"] This is a brand new RM50 head. I just got it on Tuesday. The resistor that I am changing sets the range for the bias adjustment. By going to a lower resistor value it increases the range. That moves the bias point for EL34s away from the very end of the adjustment where the potentiometer is not very linear. [/QUOTE]
