    The crystal ball is looking less hazy...

    Wiki is helping. Seems like you're referencing a SET with a parafeed output transformer stage?

    actually I skipped the parafeed. Parafeed (parallel feed) is a clever way to reduce the demands on the output transformer by shunting the DC plate voltage through a capacitor. Capacitors block DC. This allows a much more modest output transformer to be used.

    Doc Bottlehead (Dan Schmalle) offered an inexpensive but remarkably good sounding SE 2A3 amp with a parafeed output configuration. Sold as monoblocks, the kits were called the Paramours :) The original price for the kits (with tubes) was $500 for the pair. One of the great hifi kit deals evah, IMO. The parafeed design allowed the good "Doctor" (probably, more to the point, designer Paul Joppa) to use a two-dollar (!) 70 volt line-matching transformer, turned around backwards, as the output transformer! :)

    The current incarnation of that design, on one chassis, improved in several ways, is called Stereomour and is rather more expensive... but close to two decades have passed by in the meantime.

    My beloved wife bought one of the very first kits sold after the initial, small beta test run of kits. She presented the kit to me as either a Christmas or birthday present (I've forgotten which) and I had the ineffable pleasure of building the amps as a project with both of my kids. They did almost all of the work.

    Still have those Paramours -- actually, I am listening to them as I type this, interestingly enough.

    Hi Doc @mhardy6647 Interesting class so far. Really appreciate it! BTW what speakers are you running with those Paramours? Do you generally run higher efficiency speakers with them?

    ... at 3.5 watts per channel -- yes, high sensitivity loudspeakers represent a "best practice" ;)

    Currently listening to the FrankenAltecs with the Paramours. I have the "Simple 2A3" amp off-line because I've been meaning for the last week and a half to install some chi-chi cathode resistor bypass capacitors to take the place of the cheap, generic electrolytics that are in it now! :p

    Oh yeah Doc, I had that duh moment early on in my info hunt: "the tube has to run at half on all the time" was the quote that flipped the switch for me. It all started clicking after that.

    OP, You got to visit Wavac site sometimes!

    Joey, coming from you, I can't believe what you said. It's Anti-HiFi, man! It's a SIN against Boulder, EMM, and God knows what else.

    I accept donations now! Contact me to get rid of your sins!

    Wasn't there a discussion about a Carver (?) Tube amp that was rated for something like 500w/ch? I seem to recall that it was rather expensive as well...

    Nope! Not heard of the Wavac monsters yet! But I have 833 bug biting my back. So, hell of quad chassis monos in the work. Weight over 200lb each mono (2 chassis).

    Power output roughly 100 Watts from 833 SET.

    Oh yeah Bud, 1W to 1000W and everything in between! All depends on the speakers you are cranking with.

    Watts mean absolutely NOTHING when it comes to audio. I have heard 8 watt systems that satisfy the most discerning audiophile and 3.2K watt systems you could not pay me to listen too....and just about everything in-between. I know you were just ribbing but a properly designed and matched system means much more to a system than watts. Watts are but just one aspect of a complex equation.
