Greetings,
Stupid question of the month......
How do I calculate the driving VOLTAGE requirements of a tube or tubes in a
passive grid configuration in the absense of a datasheet specifiying same?
Example: I have a datasheet for an 813 that clearly specifies the peak AF/RF
driving voltage requirements for different classes of operation and service,
but the datasheet I have for the 4-400 only shows the DC values required to set
the desired class of operation and element dissipation values, etc.
I'm playing with the design of a 2 X 4-400A passive grid configuration and am
not sure as to the input transformer/swamping resistor arrangement.
I'm also assuming 100V pk for a 100W transciever. ( someone please correct me
if I'm way out in orbit somewhere!!! )
Many thanks!
