I make my living in pro audio, which here is mostly guitar amps these days. I help a lot of guys with their projects in the area.

Reading that link you gave to your website reminded me of the scene in back to the future when marty hooks up to the Docs experimantal amp -lol-
Ive had the same feeling with my 6100 head and 1960 cab stack but it never blew me accross the room (i wear lead boots when playing)

Just about to start my first guitar amp project.

Sold my Marshall silver Jublee 2X12 combo (god I miss that amp) because it was just too loud and you needed to wind it up to get the tone so I never really used it enough.

I'm now about to undertake building an early Fender Champ (6SJ7 pre, 6V6GT power) clone. Probably going to make it into a mini head and seperate cab. Hopefully this will give me the crunchy grind at much lower volumes and if I'm recording any amp is loud with a mic 2" from the driver.

Craig405:
My neighbors think that the whacky DOC lives next door. No Delorean in the driveway though.

Puggie:
I built a 6SJ7 - 6V6 amp a while back. Try several 6SJ7's they don't all sound the same. I like the old metal ones that no one wants. For a really rude distorted sound plug in a 6SK7, it is the same pinout. Distortion is dependant on the bias. The "Champ replacement transformer" from Triode electronics sounds great in amps like this and it is cheap too.

Default Both guitar amp & home tube amp guy

I play with both tube home entertainment & tube guitar amps. I could never let go of the guitar amp side of audio.

I have some gee-tar related stuff here:

http://boozhoundlabs.com/

There are a bunch of guitar geeks in my town, and our next big project is a Fender Pro Jr. tweak-fest. Basically take these inexpensive, relatively good sounding, circuit board laden monstrosities and see what can be done with them. Any other Pro Jr. tweakers out there?

Hey guys, just started getting into the whole DIY tube amp thing. Been playing off and on for about 15 years and the thing that got me interested in this is that I have noticed that low wattage amps have little if any options on them. You are lucky if they have three tone controls let alone multiple channels and forget it if you want to go stereo.

I build bespoke amps on occaision for geetarists. Doing a custom rig now for a guy who tunes down (B or C#) and is thinking about going lower.

I play bass.

tubeamp.com (sorry can't find your name)
I want to do another 813 based poweramp for myself for home/studio but I'm finding it hard to justify the weight and effort when a simple EL84/6V6 rig works well into my 100dB/W 1x15 (x2), 1x12, 1x1"+big horn rig.
Your 833 rig made me laugh - in the best way. Awesome!!

Any rational person, or anyone who gave this a serious thought would find it very hard to justify it either. Fortunately, I have never been very good at either.

When I have the time to play my guitars, I usually use an old Guild Ultraflex Amp. Try to find any info on that one. It is a biamped guitar amp with about 35 watts per channel. 2 speakers, the bass channel feeds a 15 inch, and the mid - high channel feeds an 8 inch. The Ultraflex knob is the balance between the two channels. Excellent tone for bluse music.

I put together that prototype amp to test out an output transformer that was going to go into an 833A stereo amp, but the transformer wasn't quite good enough, so I plugged the guitar preamp into it an let it rip. It sounded awesome. I can't get that sound out of my head, so I just have to build it. I envision a clear Lexan case with a glowing red 833A and blue glowing 866's inside. Impractical? Yes! About 100 pounds, and larger than my 2X10 speaker cabinet, but it will be the baddest looking amp in town, with the sound and the power to match. The only thing that I am missing is a .5KW 600 volt industrial control transformer. (budget power transformer) When I get one cheap, I will build the amp.
