Wired in a filament transformer, have a 5U4 rectifier in there, B+ of 465 dissipating 19W per tube (I might put 5881 in there, yet). Rewired the doghouse, have room for 1 more node now, might have to ditch the UL because the lack of filtering (47uF is all I felt comfortable putting in as first filter stage being tube rectified and all). There's a bit of 120Hz hum that I don't care for, now. But the amp still sounds like absolute garbage. Through 1x15 with plenty of handling (200w Emi Legend) or a 4x10, Jensen Mod 35. I don't care for the volume and tone controls at all. Either channel gets into loose, flubby bass that overpowers everything, and does a pretty good job of sounding like germanium Fuzz if you crank the volume knob, even a little bit. This big, huge, UL OT...could it be the issue? Producing too many lows for the guitar speakers? I have Channel 1 somewhat marshallized at the moment with 1st gain stage (fully bypassed) into a cold-clipper (10k unbypassed) then into a warm stage (820 unbypassed). It might be cool if it weren't for the ovederpowering bass flubbage. Same with Channel 2, which I haven't really messed with from FM's HiWattish circuit there. The PI, is LTP pretty much. Is there anything there that could be causing the overall crappy tone? I believe the LTP was designed based on the following comment: Here is the circuit: You think that LTP with one size using .01uF and the other side using.1uF is a typo? I'm almost to the point of clipping out the whole circuit out from the PI back, and starting over. And if I do that, it's getting the 5F6A treatment in Channel 1, and EF86 in Channel 2.
