I wish that Jon could actually experience this and see that his
thinking 'outside the box' isn't going to be an automatic revelation
that 80 years of radio has simply overlooked.
Thirty minutes on the bench could save 'light-hours' of ramblings.

I don't follow your reasoning on this, what is Jon going to learn in
"Thirty minutes on the bench"? I would venture next to nothing? Thirty
weeks on the bench might be more like it, and even then there won't be
time to explore all avenues. As far as 80 years of radio go, Jon's
constraints are different than might have existed when tube radios were a
mass application, he may be able to make different tradeoffs than were
practical then.


It took years' full of late nights to fully understand tube audio amps,
and months of work to re-design my ex Trio AM/FM receiver,
and then another month or two full time to build decent AM only radio, from
antenna to speaker.

30 minutes is nothing.
