I would be interested in knowing what the symptoms of different amounts of air contamination are.
What happens if the crt looses 1-2hg vs 10hg, at what point do the filaments burn up...
Maybe miniman82 would know??

you know its funny i was thinking of the video you posted awhile ago about the crt that had the brass nipple on the end. what a dumb idea for holding back that much vacuum. and you seemed pissed at that finding.
