Originally the amp started with true Jose master with siwtchable 20V/20V diodes but eventually the owner( My brother) preferred the standrd JCM800 PrePI master. That amp had everything feature wise, adjustable NFB(which you could make it loose and very plexi or tight like a Splawn), Depth mod, footswitchable gain boost. I can't remember if I did switchable bright caps on the gain pots or not I don't think I did. The amp was a hodge podge of ideas, Cameron, Splawn, SLO. That amp moved alot of air I originally used .1uf coupling caps in the PI with 82K bias splitter resistors because I used 6550 tubes for the punch and longevity of them, he loved the shitton of bass in the first iteration of the amp but could be a bit woffy with the dpeth mod, he was chunk junky...he was into Sevendust and such at the time
but he and I wanted the amp tighter so I experimented and ended up with .047uf coupling caps in the PI with the 82K bias splitters it tightened the amp up nicely but it still hi hard in the lows.I ended up doing elevated DC heaters into the center tap of the heater wire of the power transformer which floats the AC heaters with DC like Cameron did on his modded Marshalls. It was sorto of an my take on a Cameron Ocean/Aldrich but my brother wanted the capability to also us it as a straight up 2203. Dave Friedman helped me figure out out to divorce the input jacks in such a way that you could toggle inputs with an AB pedal and not use a relay. It worked pretty good made a little clunk but it worked.
Here are some clips my brother made of it, his playing is mediocre but you can hear the tone of the amp.
We are running the 50 watter and 100 watter in stereo in this video, the 50 watter was a Mod5 in the video but was changed later to a Cameron Jose with a standard JCM800 master volume with a 3 way cathode selector 2.7K/.68uf(Evox/Rifa) 2.7K/68(Mustard cap) and 10K cold clipper on V1A and I think a depth mod it was an angry little amp I wish I had gotten more clips of it after the final mods. He was running chorus in the clip, he liked that Zakk Wylde type of tone. Guitar is a lat 90's MIK Epiphone Les Paul custom with a Suhr Alrdich pickup, speaker were Celestion 12H30s anniversyaries and WGS ETS65's and one cabinet had Celestion Greenbacks.
