Accoring to Eimac specs, the idling current should be 110 mA at 5000 V,
so I think 150 is too high at 4600.

I wouldn't put more than 6 kV on the anode of a 4-1000A. 6 KV is the
maximum that Eimac specs, or am I missing something here?
What I want to know is if ANYONE is able to get the 2050 W out that Eimac
claims with a plate voltage of 5 KV, and plate current of 650 mA from 90
W of driving power? This is from an official Eimac publication!
