In my old age, I’ll stick to solid state..I believe it's about 1.2 watts (per channel) at 5 or 10% THD (10% was the prevailing "hifi" spec when amplifiers like the Zen -- but using EL84s in their native mode as pentodes -- were widespread). It is a very low powered amplifier, even by my standards, which is why mine's packed up in its little box.
Only 1 OPT when my SE84B was new, FWIW (serial number 190, if memory serves...I could check). The secondary was 6 ohm, which Deckert touted as "optimal" (I am sure he used fancier words, and more of them) for either 4 or 8 ohm nominal loads. I can tell you it sounded pretty awful driving a pair of 15 ohm Lowthers.
PS You, perhaps, should've tried SE 2A3 before you gave up on SET amplifiers.
Just don't try a single-ended 2A3......
Say what you want to about this amp but there is something to a system that sounds so good you don’t want to stop listening.
The 414 is a very, very sweet sounding driver.In a few months I will have my hands on one to play with.
It will go with an Altec 604e specified at about 101 dB.
I'll also try it with some home brew 'Cornscalas' using JBL drivers and a pair of Altec dual 414 with 806A tweeters in an Uichi horn. (They are also 100+ dB, so I want to compare and see what up!)
Gonna compare it to a 300B amp.
Purely being a subjectivist, I admit! Toys.
That is cool!
Unlistenable. The purity of the tube sound completely ruined by the transistors in the Revox.I've had one of Deckert's "Zen" amp, the SE-84B morph, since the late 1990s.
It... actually sounds pretty good.
It is very quiet (in terms of hum).
It is very, very very low powered.
