To bring this back to water cooled tubes ... one can't raise 
the pressure for two reasons.  The systems are generally 
run unpressurized and there is still a limit to the safe 
temperature for the seals.  

Typically, water cooled tubes - at least those I used in 
the TV transmitters want to stay below 180 degrees or so 
at the anode outlet.
