It depends on the plate voltage.  You have to look at the Eimac data
sheet to make a determination.  As far as I know, the Eimac Data sheet
is the standard the industry looks at when designing an amplifier.
I'm not aware of other data sheets but I have not gone looking for
them.  Amperex probably has one.  Maybe Penta also.

Yes.
