I am building a single band hf amp. I am using two 3-500Z tubes. The specs for 
the tubes say
4000 Volts dc max. I keep hearing people volting these tubes in standby above 
this voltage 
and when they transmit the voltage sags to 4000 vdc or a little below. Is this 
bad for the tube?
If I figure correctly 2800 volts ac full wave bridge and after filter caps I 
should get  4032 volts dc
2800 X 1.44 am I correct? I will be bombarding you with questions cause I want 
to do this right.
Thanks Mike N8FWD
