Where Have All the 2A3 Amps Gone

Atmasphere, forgive my ignorance (re trannies). I didn't know it you. Your current amplifiers are OTLs. Question for you. My speakers are Zu Presence which contain an onboard subwoofer amp. Are there any concerns connecting your OTLs to such a speaker?

Yes, as Syntax mentions, there is the need to pair up these amplifiers with highly efficient speakers of a good design.

I am aware of one talented chap in Europe that has a very good highly efficient speaker design. Unfortunately, he is also famous for missing delivery schedules, so now new orders are restricted because customers have resisted prepaying with him; therefore, they are resultantly resisting suffering the interminable wait...delivery miscues have become the internally driven bottleneck to restrict the future order flows.

It would be nice if the high efficient speaker space would increase.

Mdblank, "Deja Vu Audio in Virginia sells a 2A3 amp. But I don't know if it's an SET or push-pull."

It is push-pull, about 15 watts, true (required two power cords) dual mono. Vu used vintage transformers in them, along with a level parts through most of it that you will not find in most high-end audio components.

I had one in my system. The only nit I could ever pick with it was the solid state rectification did not provide the same level of romance as tube rectification would. Of course, that's a choice every tube amplifier manufacturer has to make, and was balanced by the very tight and powerful bottom end. The Deja Vu drove all of my loudspeakers to very (110 - 120dB at the listening chair) high SPLs across the entire frequency spectrum without any sense of strain. Overall, it was an absolutely spectacular amplifier; one of, if not the best I've been around.

Audion also has a few 2a3 choices for you--

-Silver Night Duo (runs 2a3, 3008, or 45 tubes)

-Silver Night Anniversary 2a3 stereo

Maybe they are all in preamps now? I used to be very curious about those 2A3 preamps.
