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.

A well executed push/pull 300 will sound very close to a good 300b SET amp but with real slam. If you listen to stuff like Beethooven's Ninth at moderately loud to loud levels this sort of amplifier is perfect with moderate efficiency to high eff speakers.

If you would care to discuss the merits of 300b push/pull amps please contact our engineer who designs our amplifiers. We have discussed building a push/pull and already have a design that has been tested and sounds very, very good.

Pricing not determined but around the 4000 to 5000 range for a new custom built monaural (pair, of course) 300b push/pull amp built with custom transformers to our specifications by Electraprint. Please give Alex a call at 925-408-1522. He will be happy to discuss the merits and how the push/pull amp compares to a quality single ended 300b amp.

One of the more powerful Air Tight tube amps makes around 80 watts and has had good reviews. They sell for under 3000 used.
