RE: clairty on a couple of issues

So, I agree with you. But we don't need any of that today.

Just run a tube where it operates at the right temperature,
uses no feedback, and just listen to it.

If the power supply, the build and the parts are good enough,
it's not going to have any competition musically.

I've had a few SETs; 300b, 2A3 and finally 45. I built up a 45-based PP amp to compare to the SET and it seemed better in every way. That one had no feedback.

The second project was to make a pentode based PP amp the same power as the 2A3 amp. That one was also UL but owing to the ease of driving the tubes only needed a 12AT7 wired as a differential amp (with CCS). Even with that there was too much gain as an integrated amp (not just a power amp) so I ran some feedback to reduce the gain. I've yet to hear an SET that can keep up with it. There seems to be something said for lower powered amps in general. But much depends on execution; in the case of that latter amp I wanted something that was also compact but built to a higher standard of parts and material quality.
