[Amps] Conditioning Spare Tubes After Storage

[Jeff Maass]

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".
