These profiles are of a very special EL84 amp from a “specific” era. The name is your clue. 24 separately captured profiles of this, both in CH 1 (triode) and CH 2 (pentode), Hi and Lo inputs (inputs 1 and 2), 4 different gain stages in each input. Incredible chime in CH 1 and some really impressive gain in CH 2. I also profiled each channel with the Master volume bypassed (Profiles have a M at the end).
