But once each tube moves into cut off, nothing is cancelled.

Patrick, I'm surprised to hear you say this. What are you trying to
tell us, that the even order harmonics are only cancelled during those
parts of the cycle when both tubes are conducting, but that the even
order distortion components reappear during those parts of the cycle
when only one tube is conducting? If you actually believe that you
should go back to the books and study the theory of harmonic distortion
more carefully. I hope you didn't get this notion from the RDH4, I
haven't read the RDH4's harmonic distortion explanation, but if this is
what it says I have just lost any respect I had for the book. In a
perfectly balanced PP amplifier the even order harmonic distortion is
completely cancelled even when the tubes are cut off for parts of the
cycle.

I'd love to know how that happens. There's no cancellation of ANYTHING once one
side has ceased conducting !

Holy ****! Did I say yet that Poopie is ignorant and incompetent?

Nah, nobody can be that stupid and uninformed about tube basics.

Poopie must be cracking a joke. For the first time in his life.

Good on yer, cobber! If you can't be smart and informed, at least you
can try to be a clown, give people a giggle.

As an alleged 'wordsmith' you of all people ought to understand what cancellation
means. Apparently it went right over your head though.

Only to be expected from an ignorant non-technical ****wit.
