Hi,
just wondering what was the main "idea" behind designing the 6545 as a ultralinear class A/B, I understand there are pros/cons to this design and (from what I know) most other amps do not operate in ultralinear mode ... connecting the screen grid to a tap on the output transformer primary.
Inquiring minds like to know ... ;-)
Thanks.

from the Tonequest interview in 2000:
What other features are unique to your amps?
Well, some of them are ultralinear.
Please explain…
Sonically, it makes the amp respond like a triode because the screen and the plate are very close to the same potential, so you get no cross over notch, and the smooth, rich sound of a triode but with the power of a pentode. It’s also kind of articulate—you hear the primary note and the harmonics without any mushiness, like with a Hiwatt, for example. I suppose I also just wanted to do something different. It’s always difficult to describe the tone of my amps because people want to know, “Does it sound like a Marshall or does it sound like a Fender?” I just know that a lot of recording artists like the originality of the sound of my amps because they tell me, “Man, that’s the sound I’ve had in my head, and I could never get it out of a Marshall or a Fender.” It’s been more difficult, because it would have been easier to copy an amp like a Bassman, but I didn’t want to do that—I never did. It’s already been done. It’s like music…certainly, you learn from the past and it influences you, but you want something original that builds on the things that have come before.
