RE: there must be a scientific reason for tube break-in

I have seen many times where a tube that hasn't been used in years or decades needs 10 minutes to a couple of hours on the tube tester with just the heater energized to "wake up" and become a perfectly good tube. Low emission/transconductance before, perfectly good tube after. I have no explanation.
