>amplifier.

€  I did not intend to intimate that the 4CX1500A was designed for Class 
C.  The dissipative ability of the 4CX1500A is relatively small compared 
to its emissive ability.    Class C simply puts less burden on the anode 
cooler.  Examination of the constant current curves reveals that the 
4CX1500A has rather good linearity -  provided that no grid current flows 
and loading is adjusted for the recommended amount of screen current in 
Class AB1 service. .    ...

>..........  If you want to clean it up a bit, run it in GG, Class AB1 as 
Collins did with their
>30S-1 amplifier.  
>........                  
€  The 30S-1 uses either a 4CX1000A or a 4CX1500B.   The 4CX1500A is Way 
different animal.  

-  cheers, Marv
