[AMPS] Calculating input impedance and drive requirements?

Greetings gurus,

I'm a little bit lost....

I'm unsure as to the correct mathematics and methods
to calculate the input impedance and drive
requirements of an amplifier stage.  Seems that I need
this info in order to design the inputs.

The project at hand is a 4x813 HF amp, cathode-driven,
with bypassed screen and bias supplies.  

Hoping this isn't a ridiculously stupid question :-)

Many thanks in advance for any assistance!

Kind Regards
