Gary,
The tube was built to run zero bias at about 2500V, you'll see about 170 ma
at that amount. If you crank up the plate voltage to 3000 without adding
5-8.5V of cathode bias you will see 250ma of plate current. 250 mils will
turn the plates mighty orange really fast.

Can anyone tell me what the ZSAC should be on a pair of 3-400Z tubes at 3000
volts?
Thanks
