I just picked up a 22+ in blond tolex. This one has no EQ and has the gain mod. I have a few questions on setting this up. One, I read in the manual that the effects loop is in between the clean and lead. If so, can I put a 5 band EQ box in the effects loop with the same effect as the original EQ equipped 22's? If not, has anyone added an EQ to the lead channel? Also, I want to better understand the gain mod and how it relates to the Master and Lead Master and regular Volume (gain). I understand that the Master and Lead Master are in series, but I am not sure how the Volume and the new mod work together. I assume that the new knob on the back is the same as the Volume knob on the front, except for the lead only.
And to recap what I have read from other posts on things to do for this amp:
Put a patch cable in the effects loop to help reduce noise
Use good EL84 matched fixed bias tubes for the output stage.
Use 12AX7 tubes, but play with V1 using other alternatives like the 5751 or 12AU7 or 12AT7.
Getting access to the hidden side of the PCB board appears to be difficult. It looks like wires have to be unsoldered in order to flip the board over. Am I missing something? I wanted to look at the caps for any evidence of needing replacement.
