Without trying to be argumentative, I agree that if one wants to call the amp non-OTL because of the "coupling transformer", this gives one an ostensibly good reason. On the other hand if one wants to call it an OTL, one can use my reasoning in the above post. I've already posted my reasons. I think that the main point is that it addresses the inherent difficulties in circlotronic OTL circuits, without resorting to a "conventional"(is that alright?) output transformer for impedance matching. Does so with considerably fewer tubes, with lower heat, lower energy consumption, and excellent reliability. I mean absolutely no disrespect to the Tenor people, Atma-Sphere people, Graaf, or anyone else. So now there is a design that provides(apparently arguably) the benefits of both OTL and traditional output transformer amps with neither of their typical weaknesses(although not perfect). I say that this can only be considered a historic event, much like the circlotron before it. Regardless of how one categorizes it, as several mentioned above, it exists and cannot be ignored. How it will fare in the marketplace is up to the performance level that users feel it posesses, at the various price points. Just like any other product.
