Monsters thread (high power tube amps)

[rvrazvan]

I would like to make a list of high power tube amps.

1000w guitar
Champ 1000 Watt Tube Amp

833a SE
833a Amp - World-Designs-Forum

any others? (i know..there are alot more others..so bring them on)

Hi!

Mine is yet to be built, with the tube in my avatar,
160W from a 851 in SE.

The Philips EL6471 seems to qualify...

I have posted this before, but you asked for it.....

I built this as an experiment. It existed for about a week or so before I tore it down since it took up the whole work bench, used all the available line (mains) power (blowing the breaker twice) and could cause death, fire or explosion at any moment.

It put out about 200 watts using an 833A running on 1500 volts idling at 275 mA.

You could build this one: http://www.audiophool.cjb.net/Misc/3Kpdf.pdf

Forum member Pete Millett (pmillett) created a mild mannered push pull amp that made 18 WPC. I performed the Tubelab treatment on it and extracted 250 WPC or 504 watts cleanly and 525 watts at clipping with both channels paralleled. See posts 425 and 438 in this thread:

uuu...some nice post i see here! NICE! Congrats!
I was talking with my winder today...and someone in romania will build a SE with this :|

Are those 6lQ6 tubes in the output ...?

[ReinoutdV]

Good afternoon DIYaudio-forum,

also already posted in a thread on this forum ( TB3/1000 is alive ! ("European 833A") ) is my amplifier.
It started as a 833A-amplifier (2 monoblocks with dedicated external powersupplies) but when i scored a stash of Philips TB 3/1000's i quickly changed to that triode instead.

Currently they run at 110 VDC / 240 mA. But what are numbers; it is the sound that is important !

Looking forward to see this interesting list grow....

Regards,
Reinout

The tubes in that picture are 35LR6's because I got 45 of them NIB at the Dayton hamfest for $4 each. 6LQ6 are far out of my price range for experiments like this.

Petes board seems to work well with any horizontal sweep tube that fits the socket, and even some that don't, with some creative rewiring. I have run dozens of tubes through the board but the 6LQ6 / 6JE6C isn't one of them due to the cost and relative scarcity.

I settled on a 6HJ5 build that made 125 WPC and posted it back into the original thread. Several builders have duplicated it with good results.

There will be some more big watt experiments in the future since I have a pair of 400 watt OPT's that need use.
