I still have a half baked 813 project still sitting in my lab. The power transformer is big, but now as big as this one. I'm still pondering on the layout for the preamp and the PI I want to use to finish it up.

...the "mega"-Champ at 1 kilowatt of power, for the really B-I-G bedroom venue (ha,ha)!
...and the Devil said: "...yes, but it's a DRY heat!"
John Chambers' 1kW amp is certainly impressive, but it's push-pull Class-AB, so it doesn't count. If it were running single ended, he'd only be getting about 100W out of those same tubes.
HTH: Your 10 watt combo sounds great. What guitar are you using to demo it?
"Enzo, I see that you replied parasitic oscillations. Is that a hypothesis? Or is that your amazing metal band I should check out?"

Again, you're writing comments on things you don't understand. The max plate dissipation of an RCA-813 tube is 125 watts. Further, it only requires 5 amps filament current verses the 25 amp requirement for the 304TL. I think with 4 813's in parallel he'd get a few more than 100 watts out of it.

I don't think you understand any better. You once mentioned you were going to try and build an 813 amp with a 100 watt Hammond OT or something.
A 304TL can dissipate 300W, and the Alum Rock guy only gets 30W out of one single-ended, so I stand by my 100W claim unless someone can supply hard evidence to the contrary.

jesus, a 100w SE amp - now we're talking
of course, you'd need an army of roadies just to move the bloody thing. the 200w Matamp bass head (4x KT88) my old bass player had was bad enough and was a two-person job.
glad you like the clips of the amp Steve, the guitar was my trusty 1990 Les Paul standard with Bare Knuckle Abraxas pickups.
