Hello Dave,

I would kill to be able to get some 800W 3000V max plate tetrodes. I
have been using two 803's and am only getting about six inch discharge
with a 1.2kW-at-2400V microwave trany. A hot baby, though! The 803 is a
tetrode with only a 125 watt plate dissapation and 2000V plate.  Check
out: http://linux.cec.army.mil/hamradio/tube/tubefind.html
That is a good info repository with basic specs for common transmitter
tubes.
 What are the tube numbers that you have the opertunity of getting?
