Congratulations Atmasphere!


I noticed today that Ralph Karsten (whom regular and even occasional participants in this forum will of course recognize as the designer and proprietor of Atma-Sphere Music Systems, as well as a uniquely valuable contributor to the forum) was granted United States patent number 10,469,042 on November 5, 2019. It covers an audio amplification technique he had indicated here that he has been developing, which in simple terms appears to me to basically be a clever combination of an analog-to-pulse train converter (as used in traditional class D amplifiers for example, among other audio-related applications), with an output stage employing circlotron topology (analogous to the topology used in his OTL power amplifiers, but utilizing solid state devices).

Link to the Patent.

Congratulations Ralph!!

Best regards,

Sounds like it’s shooting to sound like his tube amps but no tubes to deal with. Very cool. Been looking forward to seeing /hearing the end result. 
It's funny, 'cause most brilliant designers look like nerds. Ralph looks like a musician, which he also is.
Thanks Almarg
And congratulations to a well respected contributor here, Ralph of Atma-Sphere Music Systems. I can imagine something like this coming from him,  that it will be a significant product. Looking forward to hearing more about it.
