[Amps] Quad Tube 4cx800 hf amp

[Peter Voelpel]

Phil, 

The 8660 is the equivalent to the 4CX1500B,
The driver tubes are 8122 I found out.

Again, if I drive a 8171 to not more then 1,5KW output ever,
it should be tuned for that power, not for 20KW

No, there is only one pair of driver tubes in class A.

I disagree with that premise.

Bigger is usually mo bettah! I over-engineer everything.
