[Amps] gg amp question...

[jerome schatten]

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,
