You really should learn to use Google rather than expecting other
people to do it for you.

Sorry, I'm totally wrong... it's the 4cx350F that uses 26.5volts on the heater, Leigh's reply is
correct. Memory isn't what it used to be..

Heater voltage, 250B is 6V (not 6.3) 250R is used in aircraft etc and has a heater voltage of
26-28V. as far as I am aware all other specs are the same, I have used both types in a 2M amp
without having to change anything other than heater voltage.
