Most will tell you it will make no difference at all but I have had NOS
4CX1500B's pop the high voltage if applied after just putting it in the amp
(with 3 min warm up of coarse).  I'd run it with filaments on and high
voltage off for 30 mins or more before applying high voltage.  Sure won't
hurt to do that.

JMHO.
