Too many "IFs"!

Those are not "Ifs".
Your driver can not fully drive the Miller by your own admission.
The cathodes of both the driver tube and the output tube are not fully bypassed.
No IFs.
You are doing the very thing you argue against. Making designing an amplifier that is perverted.

I fully and completely disagree.

You disagree with yourself?
You said that your amp starts rolling off at 15kHz.
The cathodes are not fully bypassed. That's just a fact.
If you disagree, show the numbers, show me wrong.

All the amps I've owned before my SET have been flat from 20-20K with distortion well below 1%. None sounded nearly as good as the SET which doesn't have "the numbers".
If Dennis just said that his amps sound good I wouldn't say a thing.
But instead look at his response to your post,
"OH! But it DOES have numbers. It's been at University E.E. labs where it astounded their engineers."
With undersized bypass caps and a driver that even Dennis admits does not fully drive the Miller capacitance of the output tube, how can his amp have good numbers?
