Mine should be here sometime next week!! This is a good mod opportunity for me, or at least I know I can handle any repairs or debugging. After sorting any initial issues, next is the addition of a master volume. Since I will be ordering a matched pair of 6L6GC, I'll probably add a 12AT7 to put in the reverb driver spot and make resistor or cap value changes accordingly. this will be my first fixed / LPT PI so Ill need to learn how to measure and set the bias current.
