[AMRadio] 4-1000A Grounded Grid Class-C

[Paul Baldock]

You hit the nail on the head with the "harder to neutralize" comment 
for a 4-1000A in grid driven mode. That's why I posed the question 
about grounded grid. The other reason is that I have a 4-1000A 
grounded grid class B amplifier that I could change to Class C and 
high level modulate.

Plan B of course is to use conventional 2 X 813s in class C. No need 
to neutralize and easy to modulate.
