Push pull 300B amplifiers

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.

I have a pair of Wright Mono 10's that are a push/pull 2A3 design. I also own a pair of 300B SET amps. The Mono 10's give that wonderful midrange magic of the SET while providing more authority in the low end and and overall dynamics and speed...this in direct comparison with both my 300B's as well as George Wrights wonderful 3.5 2A3 SET amps which I owned for a while. The only compromise, to my ears, is in the sense of airiness and delicacy that SET does oh so well. It is by no means a big compromise though. I've never heard the amp in question though, so cannot comment directly abotu that amp.

I've had no experience with Canary amps but a friend whose ears I trust has - he says they are very well made and quite musical. Also have had no experience with P/P 300B amps since I'm quite happy with my 300B SET at this point. However, at $200.00 - $850.00 a pair for output tubes (and you'll need two pairs) retubing gets quite expensive. I also don't know how long the power tubes will last being run this way, maybe longer.

By the way, Bobheinatz, what 70 watt amp are you using?

I'm sticking with the SET mode.

TWL, Berning describes the ZOTL amp as class A push-pull. Even though his design is truly unique, I don't see how you can call an OTL amp an SET in any traditional sense of the term.

In any case I would love to hear it.
