Just to be clear...

No, I was not trying to say the PPP 6L6 amp would do 80 watts in triode mode. What I was saying is it is claimed that it operates in class AB1 in tetrode mode but when switch to triode operation without a change in bias current it operates in pure class A. I was also just informed that the bias point is speced at 30 to 35 ma and not the 28ma I stated above. I don't know what the claimed wattage is in triode mode.

But leaving that model alone and looking at the current tiny triode which has the specs at the website, I just don't see how one gets 25 watts out of a quad of PPP operated triode strapped EL84's. I would think 16 watts would be about the max possible. Even the claimed 40 watts in AB1 tetrode mode seems hard to buy without going over the tubes ratings.

This thread is not intended to slander anyone. Manley has a reputation and it speaks for itself. Instead I was looking to see if I had a misunderstanding or if the operating points might just be above normal maximum ratings. Plenty of guitar amps operated tubes above ratings.
