Good quesiton. Haha. I've seen that website/company before, someone linked to it in another forum I frequent. I guess they're all about custom made amps, and it seems to me that there's probably more than one ripoff or two.

Worked for me. Might be an issue being a secure site. Check your browser's security settings. The amp uses a Marshall transformer set that doesn't have the ultralinear taps. Also the amp doesn't have the Pi filtered B+. It's more of a conventional design. There is also a 200W amp he's working on that's still in the prototype stage.

Sunn Fans,
I posted this amp earlier under the D.I.Y. forum for those interested in building something similar to a Sunn 60 watt head. As Loudthud points out, the transformers are not the same as Sunn, nor are the phase inverter or the tone recovery tube. So the only real similarity is the use of a pair of KT88's (or 6550) output tubes and a vague cosmetic resemblance to a Sunn Model T.
I doubt that there are any grounds for copyright / trademark / patent infringement here. Frankly, I'm surprised that Sunn didn't get into legal trouble with Dynaco back in the 60's. Sunn's designs were much more closely based on Dynaco's circuitry than Weber's design is related to Sunn's.
I've built one of Weber's 6M18 kits......basically a variation on the Marshall 18 watt platform. There are a ton kits and boutique amps out there based on Marshall, as well as Fender designs. Remember that Jim Marshall based the first JTM-45 on Fender's Bassman (5F6A), and Leo Fender based the 5F6A on a Western Electric circuit! There is very little completely original tube circuit design out there. Most amp designers have studied the classic circuits and come up with variations, modifications or new combinations. This makes for a lot of "flavors" of amps out there. And just like with cooking......you can stir up your own receipe at home if you are so inclined!
Ted Weber makes very nice, well-priced kits, geared for experienced hobbyists and amp techs, that you can build to his stock schematic or hot-rod to suit yourself. I just thought some of you guys might be interested!

besides the name of the amp and type, i'm not sure anything else could be copyrighted.  that wouldn't be very benificial to one manufacturer of components over another manufacturer.  if you really do some searching you can find "clones" for just about any sought after amp and pedal thats out there today.  and even some vintage ones no longer made.

this is my hippy dippy mind workin:
old amps have a certain mojo that i respect and look for and  play.
do they sound different than modern amps built to the same specs?
well i know the old Model Ts sound a world different from the Fender versions-
i have a Marshall SuperBass from '71 that sounds totally different from the modern day superbass.
so when i said 'is it legal' i was talkin Karma-wise.
merry new year yall

The Fender version of the Model T has very different circuitry than the old Model Ts had. Hack, the second generation Ts had a very different preamp section from the first generation. So it's no surprise that they sound different.

Unless someone can verify that the circuit is taken from a Sunn and unless the person who owns the rights to the design sues...yep, it is legal.

You only need to change a few thiongs to make it a "New" amp.

It wouldn't matter if the circuit was taken from one of the classic Sunn tube designs because those were almost identical to Dynaco products already, plus its been so long those circuits are now in public domain.
