Amp Gain staging question

Amp Mad Scientist said:
Basically an amplified signal cannot be fed into one stage and another without attenuation.
It would overload the next stage...
so it goes for conventional amplifier design.
(these designs were all copied from hi fi amplifiers phono preamplifiers) which were built in the late 1930s - and 1940s.
The master volume control was also invented in the 1940s.
The "cascade" gain stage was in wide spread use in the 1940s. (actually it's a "plate follower")
The "cascode" stage was in wide spread use in the 1940s. (It's a cathode follower)

Randall Smith did not invent any of the above....but continues to falsely claim that he invented all of it.
(A complete deception / an outright lie).
He simply copied it from other old designs.

The basis of all modern designs is the Fender Bassman (which was copied by Mesa Boogie and Marshall)
And continues to be the most copied design, and the basis for all modern guitar amplifiers.

This, regarding inter-stage attenuation, & regarding the Fender Bassman, broadly speaking, also yes. We must remember though, that Leo & his team did not really "design" the bassman, rather, they lifted they circuit block designs straight from the pages of RCA tube application manuals (as they did for most all the early Fender amps. If you check some of these publications out we can easily find examples of these circuit block designs, & see that Leo & his team have in most instances used the suggested component values.
Yes, the 5F6-A Bassman is very much copied &/or used as the basis for other designs, but the basis for "ALL" modern designs,,, most definitely not. There are just so many amp designs that have absolutely nothing in common with the Bassman circuit. Hell, even though the chosen output transformer was suitable for reproducing bass guitar frequencies, the circuit itself isn't a good "bass guitar amp" design. I believe it was the Ampeg design team who started with a clean sheet of paper & produced the first tube amp that was truly designed for bass guitar, & has nothing in common with the 5F6-A. Cheers
 
It is my understanding Leo Fender was not happy guitarist were using the Bassman so he designed the Concert amp
I own a 1959 version 5G11 it has the Triad output transformer like the 5F6-A but no GZ34
I just got in a 1964 Concert will see the changes are.

I don't have it at my house to confirm, but isn't the Blonde '63-'64 Bandmaster also a AB763 circuit?
