I've often looked at my Ampegs' design and am yet baffled by what's really going on; anybody?
The main area in question is the 6K11.
Massive plate resistors, feedback (or is it feedforward) and smaller blocking caps - but they still sound clean and bassy. I'm about to modify the duplicate channel for distortion by adding 820 R/1 UF to the cathodes and then 100K R to the plates and move the volume pot after the 2nd gain stage.

~I'm trying to get a Fender preamp to trickle out tubey vibe at -10 dB. What could we learn from Bill Hughes and Roger Cox to this end?
