    I am looking at Traynor YBA-1 variations and one version has 1K5/125uf on V1A and V1B How would this change behaviour as opposed to plexi values ( currently in there )

    I ordered and installed a Jensen P12Q and I am very very pleased ! HAvving much fun with this thing. IT needs getting used to but I am getting great tones both with an L.P and a Gretsch 6120 so far. Now I want to do the Rob Robinette NFB switch mod but I am uncertain about one thing. When I look...

    Tryed the 4 x 12 It is surprising how much impact speakers have on this amp. I also removed and re installed all tubes, things changed a lot ! Still ordered a Jensen P12Q to replace the Weber alnico signature currently in it. I find it breaks up much to quick and colapses under bass frequencies...

    Picked up a Tweed delux repro last night. Looks very well done with good quality parts... Except no highs, sound dull with little dynamics. not much difference between the two inputs either... ANy clues ?
