>maximum frequency of use.

The Western Electric 701A is a radar pulse pentode rated to 15 MHz.  They 
used to be available surplus from WW II for as low as $1.95.  An article in 
"The New Sideband Handbook" by Don Stoner (1958)  says the interelectrode 
capacity is high.  A socket is made from split copper tubing.  Filament 
power is 7.5 volts at 7.5 amps.  Plate dissipation is 200 watts.

If you like, I could scan the information and send to you.  They are an 
interesting looking tube.
