A little place in North Hollywood made a nice Class-A tube amp back in in the 1970’s that used two Eimac 1000Z tubes and would easily top 1.5KW rms output!
Of course it had a plate transformer that weighed 200 lbs, a 2nd
transformer (for the filaments) that added another 40 lbs to the total..
..I think they were called Kenton Audio Laboratory..and the amp was
dubbed “The Theater Reference Amp”. We had a pair of them at KPFK-FM studios in the listening room..driving a pair of stadium-series (double 15″ drivers) Klipsche Horns. Sounded great!

There are many tube amplifiers making lots more power than this. Production ones include the Altec 260,1570B, and others, the McIntosh MI200 and MC3500, and….about two dozen others.

Now you all know what I mean when I talk about paper powered amplifiers. Any pure class A amplifier is running a half power in total quiescence (dead quiet). This is a pretty web page, also a technical selling ploy that I hope has become antique. The chinese are trying to dump oddball tubes on our market, and I say that that is what you are viewing here with this ad. Just search eBay.com and you’ll see them with free shipping and russian tubes. Push pull, - will burn up as soon as you turn them on without the exact right load on the speaker outputs. Now I’m laughing too hard to keep typing…

I have seen a Diagram for a 500 watt push pull output (Philips) with the HT at 3KV, response was something like 50Hz to 6Hz and this was more than 20 years ago. Personally I hate valves, they a crap in producing HiFi. If you been brainwashed into thinking valves are the best then you must have more dollars than cents (sense). They sound great in guitar amps and old style radio.. Distortion is what these babies make! You must be crazy to spend 55.000 dollars this old technology. Damping Factor of 20 lol
