[Amps] 3CX800 and blower

[David J Windisch]

Does a 3CX800A7 require airflow any time the filament is lit, like, say, 3-500Z glass tubes with tender seals and 70-watt filaments?

I'm thinking of leaving the (unobtanium) blower turned off, to lower wear and tear, until I need the power.  

Yep, I'm aware of the potential hazard of a senior moment: I have in mind a no-blower-no-operate interlock scheme.
