I wonder if he's referring to cancellation of the second harmonic generated in the stage?
Follow Ups:
It appears he was referring to the cancellation of the signal , not the distortion

no matter, turned into a good thread anyhow!
Yes he is.
He is also thinking of balanced connections where all things in the common mode are rejected.
He is also thinking of unbalanced signal where nothing can be in the common mode.
The problem is, he doesn't understand any of them and is thinking of all three of them in a very wrong way.

I would love to see the explanation he'd give should he have decided that PP amps sound better to him...LOL
I'm also curious as to how far from the usual Horsepower Race, gNFB designs he would have deviated; his SE stuff is RotM.
cheers,
Douglas
Friend, I would not hurt thee for the world...but thou art standing where I am about to shoot.
I think if he was PP guy he would a uneducated/ignorant PP guy, in much same way as he is a SE guy.
RoTM = run of the mill?
If so then I strongly disagree.
He's SE amp is poorly designed from the power supply to the driver stage to the operating point and load impedance of the output stage.
"Run of the mill" stuff is better than that!

Hey Tre, wondering if you happen to have a schematic of one of dennis amps?
is this why you said they are poorly designed because you seen his schematic?
Thanks
Lawrence
I have, more or less, seen a schematic.
When I talked to Dennis he indicated that there were a few things that were very close but not spot on.

I think you may at some point be able to draw reasonable conclusions from a description. High-mu triode, direct coupled to a 2A3 grid paints a fairly solid pic. The admitted frequency response matches this practice.
The description of the PS allows other conclusions to be drawn, and operating responses modeled...:)

Yes, Run of the Mill...:)
It has B+, it has a low mu triode final, and a high mu triode voltage amplifier.
As to implementation, it is set up as a signal processor...again, nothing surprising there, save perhaps the magnitude of the processing.
cheers,
Douglas
