Hey Stan, been a while, hope all is well. Basic rig run down is the Duncan Custom with the same old beat up, 1 piece Swamp Ash Strat w/old, original 6 hole Fender tremolo. Brass nut of course. Only pedals are the homebrew EP-3 and an analog delay right after it. Just like the echo-plex would have been. Delay only on for DTNA. Amp is everything on 10 except VOL I which is only on about 6. Yep, amp has lots of "IT", for lack of better words. Was always changing between 820/.68 and 2.7K/.68 on V1. I Liked both so I settled somewhere in between at 1.5K. .0022 coupler. Filtering is 16uF on the pre-amp, 16uF on the screens, 100uF on the PI and 50uF mains. V2 uses a 330uF bypass. Like that low end business there. I do have an additional .022 in parallel with original .022 for the PI input coupler so that would make .044uF there. I like this a lot. NFB has 100K resistor on the 8 ohm tap. Old RCA 6CA7's for power tubes, one long plate Syvannia 12AX7 for V1 and the others are miscellaneous RCA's. Variac on 85VAC which with the original JTM-45 RI Power transformer that this amp uses, put the plate voltages waaay down low. Like 275 if I recall. So had to change the bias resistor to get the bias up around 70 or 72mA's for this. And just for fun and more sag, a GZ-34 tube rectifier.
One speaker output to a 20 ohm load and the other to a home brew line out with the little Jensen 4:1 step down transformer. The power amp is the home brew 68 spec 100 watter (all the same specs) but modded for power amp only. Pure clean power with no tone controls. Volume and presence are the only knobs that do anything. Cab is a Marshall 4X12 w/cane grill clothe and Jim Seavall's Paper Voice Coils pre-rola, 20 watters.
