Push pull 300B amplifiers


Any opinions on this topology compared with SET 300Bs or push pull KT88/EL34s (my only point of reference)? Any reason push pull 300B amps not more common?

Am considering the Canary 301 Mk2 or ASL AQ1010DT for 90 db easy load speakers (Equation 25). Good idea?

Any thoughts appreciated.

I believe Kevin Kennedy's PP 300B design would be great. Pure class A PP. The Citation II transformer will do great here too. Most of people don't like PP 300B because of the cost. You can get similar performance with KT-88/KT-90 PP tube amps running in triode mode. I think it is a waste of tube at this price range for PP application.
