Hi Doug,
There was a long discussion that included RF fdbk on this group last December.
Here is a pointer into the archives:

Amps fans,
I have only subscribed to this reflector for a few months, however I
have never seen any discussion on negative feedback in linears to reduce
distortion. I plan on feeding a few pf's from the 4CX10000D plate back
to the driver cathodes in a capacative voltage divider configuration.
(why a 4CX1000D?, because I have 4 of them with sockets) This topology
should be frequency independent. I'm planning on a neutralized class A
amplifier, and from10 to 20 dB of feedback. I wonder if anyone has
successfully done this, and why it isn't done more frequently? There
must be a can-of-worms here I'm not aware of...
Thanks all,
Doug Ronald
