[AMPS] grid voltage swing

[Bruce plantin]

Larger tubes such as a 4CX3000A  require very little drive power, but the required grid voltage swing is very high.
What is the proper or most commonly used method of deriving this voltage swing from the standard 50 ohm driving source? I have not looked at the data sheet lately, but believe its over 200 V P-P for the 3x4.
I have justed started looking at this reflector. Can anybody help?

Regards,
Bruce W3BP
