[AMRadio] RE: Using a Ranger as a driver

[Jim Wilhite]

I forgot to mention John, you might explain how a Class C final sees 
higher impedance when the plate voltage is lowered.  As I recall Zp is = 
Ep/(2X) Ip.  So a Ranger with 600 V. on the plate with 120 ma. is seeing 
~ 2500 ohms.  With 300 volts at the same current, it should be seeing 
~1250. Zp.

Maybe this will help some of these people and you are much more eloquent 
than I.
