"Doesn't Allen use the Russian 6H30 variants for a gruntier driver?"
He might do now, I don't know."And doesn't he use a CSS in the tails of the output pair to avoid those huge bypass caps? And some form of fixed bias? Combination bias maybe?"
I believe he did introduce a CCS in the OP stage but I've never seen that version. I was thinking of the original PP-1C.
"When copying someone's design, it's best to start at their design before wandering off elsewhere otherwise how will you know how close you are to the excellence of the original? i.e. where the designer's started himself."
True, I got carried away trying to address the questions!
