[Amps] Designing the Cleanest Linear with RF Negative Feedback

[Tom Cathey]

Correction:

It was pointed out to me that the cathode resistor for negative feedback is 
to be used only for a grid driven [grounded cathode] amplifier to generate 
degenerative [negative] feedback.

In a cathode driven [GG] amplifier, the cathode is in phase with the plate 
and it will not work. A different method must be used for neg feedback.

This is why my GG triode did not show any diffence in drive when I  tried 
the cathode resistor.

I saw the idea in the archives and must have missed the fact that they were 
talking about grid driven amps at the time.
