I have a pair of 4CX800A tubes that have been on
the shelf here for a few years (and for an unknown
period before I got them). I'm about to swap them
into one of my Alpha 91b amps.
Is there a recommendation to let these tubes run
without HV for a period before pressing them into
full service?
I did a search of the archives, and it seems that
there is no consensus on the need for this procedure
for any but the largest "tubes with handles".
