That's too bad. That prevents use with 1500W output and I 
did not want to use much more than 4 kV.

How much bias do they take Roman? It looks like the mu is 
low and the input impedance is high.

I'm trying to find a cheap triode that will run steady 
nearly 100% on time at 1500 watts output with 100 watts of 
drive. I also want instant heating.
