[Amps] Designing the Cleanest Linear with RF Negative Feedback

[Gary Schafer]

Hi Tom,

Here is some more info for you to look at. Qst July 1967 page 34 is an 
article by Orr on super cathode driven amps. He shows the difference in 
IM performance on the 4CX350 in this configuration which if I remember 
right is about 15 db better than grid driven.

Other good stuff in the article about feedback too.
