query: schematic or feedback re: Atma-Sphere amps

Posted by radiance (M) on May 25, 2006 at 14:21:36

I just found the Atma-Sphere site - boy am I TIRED of OTL sites saying THEIR amp is the one and only, the best, the patented, etc, etc. Oorg. Ugh. (Really tired of b___s___ hype).

NONETHELESS, I would really like to look at the circuit they are using, with 6SN7's driving 6AS7G's in a transformerless output design. They claim they have a patent, but don't list the patent or the schematic on their website. If they have a frigging patent, why are they hiding the circuitry and the patent? (To keep a DIY like myself from making the amp for myself from scratch, of course!!:) Does anyone know where to find it? I looked on the tube data site but Atma-Sphere was not listed in their list of schematics. Does anyone have any feedback on whether these amps are better than any other OTL (The Beast, etc, etc) or - for that matter - SET amps (Angela 300B, etc, etc)? (Boy I'll bet these Atma-Sphere amps put out some heat! If nothing else, they'd probably be great at heating an ice-fishing shack!!)
