Sorry, I thought you were saying it was a Gonset 500W (read: 500 watts)
amp. My apologies.

Do you know whether this is supposed to be a linear amplifier, or class C?
For 1954, I'd think only class C, unless people were doing linears for AM
use back then, since SSB was still pretty uncommon. And if it's class C,
seems to me that's really unusual, to have marketed a separate amplifier
like that. Wonder whether it was intended to be used with a lower power
exciter?

Do those 807s have a slot filed in the bakelite bases? If so, they were
modified to disconnect the suppressor grid from the cathode, as they came
from the factory. This was necessary in order to run 807s linearly. 1625s
bring the suppressor grid connection directly to one of the 7 pins so they
didn't need modification.

And not all 807s had the suppressor grid wire coming through the envelope,
either; some were connected to the cathode inside the glass so they
couldn't be used in a linear amplifier.

You might check ads in the back of the ARRL Handbook of those years for
full-face photos and possible details of the Gonset logo at that time.
Natcherly, QSTs would also be good to check.
