[Amps] gg amp question...

About half of that will be right.
Voltage swing is less then 2.2KV, and the conduction angle is not 360°.

R = E/I = 2200/.4 = 5500 Ohms.

Close as you're gonna get.

I'm trying to modify my pi network on a pair of gg 813's to work on 160.
Looking back into the plate circuit from the pi network, how to estimate the
ac plate circuit impedance that needs to be matched by the pi network?

My handbook has a series of tables (11 of them) for determining C(load),
C(plate) and L for various values of Z(plate) for each band.

Basically it's a 10db amp that runs ~450w out with 2200v on the plates and
key down Ip of 400ma

Thanks for your insight,
