Hi Chuck,
  You can see how Hughes Aircraft used to figure that on the bottom of this

I see a lot of  formulae(is that plural???) on determining the output impedance 
of a tube.
some say just plain plate volts divided by plate current, some have a 1.8 x 
formula  and so on. I Want to determine
this gu-84b impedance so I can start work on the tank setup. I run 3.9kv and 
I'm GUESSING 2 amp.
 I stuck a 2k in there and played some with the values so far and things look 
ok, no suprises. this is
 my motive for the question. lets hear some opinions! thanks as always.
