Interesting ;)

I see they mention that this is a Class B amplifier. I was always under the impression that tube amplifiers are Class A :o

Nope, Tube amps can (and mostly do) work in Class B. That's the only way you'll ever get decent power while keeping dissipation under control, no matter if you use tubes or transistors.

What I find interesting is that they managed this kind of power when even today (56 years later) it's not common. I wonder what the speakers looked like that they connected to this.

"... without sand." Forgive my senility, but what does that mean?

It's a dumb statement the tubophites use to say silicon. Fact is, the glass of the tube is also made out of sand :D

" 1kW per channel without sand"

How did they make the tubes (envelope)?

See what happens when you decide what to post before you do and you dont yet read the latest.


Anyways, I always liked this one: What is faster? A chemical process or an electron moving in a vacuum?

Mmmmm ...
not to be nit-picking - but no; unless one does not recognise class AB. There were/are many tube amplifiers working in full class A, as well as MOSFET units up to 100W (not for summer!) and an odd transistor one. Can't recall makes now and too lazy to google; not that much of an issue.

Heh, I should've said 'High Power' Tube amps. If you happy with 10-20W there's many SET and class A ones around I'm sure.

Or smaller. Pretty much every(*) table-top, battery portable and radiogram from the 40s, 50s and 60s used a single tetrode or pentode in class-A, as the output valve. That's a few million class A valve amps.

Yes, there are exceptions. Not a whole lot though.
