I am quite sure this is what he meant. We were talking about cleans in the preamp section and there was little to misunderstand. He had a cult following for attaining this and from accounts Ampeg was one to cultivate the clean sound.

I believe you, but I don't think he was right. No disrespect intended to anyone. There is so much myth out there when it comes to tube guitar amps, it is hard to know what is true and what is not.

Why not try it on your breadboard and decide for yourself? Use first a half-12AX7, then a small-signal pentode ahead of the cathodyne (or source-o-dyne) PI. Listen to it, 'scope it, and see what your ears and oscilloscope say!
