The sound clips don't sound very good at all.

That's not a tube, it's a fish tank.

Do they make a yellow-jacket for that so you can run EL34s?

They will be very expensive. Like 1.5-2x SLO price
At the moment there are just two prototypes in existence.
I agree that the head must have Midi. Or otherwise hello to tap dancing on the 13 button footswitch
Yeah, that is a "River Dance" pedal board.....main reason I went midi with the Meathead. All the functions are also CC so if feel the need to River Dance, you can still do it on your midi controller haha

Just a few notes.glpg80":39kvx2o4 said:
The 833 is a single triode AF power amplifier and modualator that can also be used as a RF power amp and oscillator.
Heater volts 10volts, heater current 10amps.
Amplification factor 35 with grid @ -10V and plate MA @ 200.
Typical ratings as a class B AF power amp:
Plate voltage 3000DC
Zero signal plate current 100ma
Max signal plate current 750ma
Effective load resistance p2p 9500ohms
Max signal driving power 20 watts
Max signal power output 1650 watts
(RCA transmitting tubes up to 4 KW input, 1956)
Chassis size(although a safe layout is a must) is no where as important as amp and volt ratings. i.e., Hams commonly use shielded ignition cable for wiring RF circuits carrying more than 2500 volts. As for heaters carrying heavy current, no. 10 or 12 wire is common.
See RIAA Handbook chapter on 'Construction Practices' for more details. My version is 1953 but the same laws apply today, we just may have better insolation and stuff now.

Very "interesting" amp for sure. And the sound clips didn't sound bad to my ears.
But I gotta ask... just HOW many freakin' variations on Marshall/Mesa/Fender/Vox amplifiers can the market support? Seriously... the differences in tone are getting to be microscopic. Features are the biggest selling points any more. And "club-exclusivity". The whole market seems like it's getting to be like the cruiser motorcycle market. Who doesn't have one who wants one?
I dunno... I really like my current Engl and Marshall heads. But really... it's always ME when I plug into them. And no matter what other brands I may own/try... it'll still always be ME. It all gets rather uninspiring and seems like the movie "Groundhog Day". More or less, the same old shit... different day. I guess that being on a gear board... I'm not preaching to the choir with this rant. But I'm getting rather bored with gear-whoredom any more. I still love to play (indeed, it's the lifebood flowing through my veins). But getting excited about more boutique gear just doesn't seem like it's gonna happen that often anymore. Luckily, for the present at least, the gear that I've got still inspires me.
Anyways.... carry-on with the discussion of the merits and drawbacks of the giant-cyclops-power-tube-amp...

Wow. For that kind of money I would just rather have Larry or Fortin build me an amp.

Im no expert but 100w of class A power would be enough to knock you over with one powerchord. I dont have alot of experience with Class A amps but a friends Vox AC30 was insanely loud with 30w of class A...mrkmas":wbhddevx said:

Well to be sure my post was directed towards GLPG80, who last I heard recently graduated as a Electronic Tech, or somethin’.
Add to that, for a fact the big surge in HiFi(especially over seas) over the last 20 years or so has been the use of obscure or obsolete tubes in low efficiency SE amps . I figured it’s only a matter of time before some guitar amps start in on this craze, much like this thread depicts. After all few things look as sweet as a 2A3 or as monstrous as a transmitting tube.
Further and more along the lines of this thread, I’ve got a matched pair of 811s still in the box from 1945, so someday over the rainbow they will be in my latest personal git fiddle amp.
Yet that will have to wait while I use the new trafos that Hammond has sent me as payment for helping them design their (somewhat) new Marshall, Fender & Vox direct plug in replacements.
Mind you none of that is a big priority for me, they ain’t goin’ nowhere and I’ll be back hitting the books soon. Won't that be grand, no more MOAAH at least until Christmas, LOL.

MOOAH, if the tube is rated at an output of 1,650W at 3kV for strict class B bias, but the amp is only rated at 100W class A, 800-1kV sounds about right. 20mA was a rough guess based on the PT size - could be upwards of 80mA but i doubt it at 1kV. you still have to supply 10A of current for the heater filaments in that tube alone.
You have to question sanity at that point. Guitar players who accidentally touch something they shouldnt will be killed instantly at those voltages and currents not to mention the power that is wasted as heat.
Great concepts but not with the technology we have out today. There is a point of diminishing returns - IMHO that crosses it

Seriously, how hot you guys think that tube gets? I bet if you grabbed it at full power it'd peel a couple of layers of skin off and fry it.

This would be a great mod for the stage.
