Ralph has been posting about his developments in Class D on Agon for a while, his new amp could make a big splash in Class D performance. |

Interesting. A tube Class-D amplifier...or at least a tube circlotron output to a Class D front end. |

I believe the Patent application states the Circlotron can use either solid state devices or tubes. I don't see the circlotron as being the main element, but what is in front of it, or the whole as a combination. Not sure the circlotron output itself is patentable. David M. |

I find the patent process questionable. I've seen patents over the years that should not have been granted. Basically "old wheels" with new names. |

When loking at innovation in amplifier technology the grand daddy of them all is Gerald Stanley who worked at Crown for over 50 years. He has over 45 patents. I met him twice at Crown in Indiana and he is not only a genius but also a nice guy who spent loads of time with me explaining amplifier concepts. One of his inventions, the Class I interleaved class D configuration has many advantages over standard class D. I had a paper on it once but can't find it. Here is a link to some very basic info about it on the Crown site. https://www.crownaudio.com/en/technology |
