For quality, I agree.  For shorts?  Listen for the snap, crackle & pop?
Watch and sniff for the smoke?

A lot of NOS tubes, let alone pulls, have developed shorts along the way as
they've been resold, re-packed and shipped over and over again.  Fortunately
not too many, maybe, but enough that I wouldn't want to risk collateral
damage using the receiver as the first tester.

When I first get a rig in, I check all the tubes.  Even if it was supposed
to be working before the trip.  Well, I have to admit, I skipped that step
on a BC-314 a few weeks ago.  Guess what?
