"...the milspec tube would be tested more thoroughly than civilian tubes"
It would be nice if that were true, but I think in fact the opposite probably occurred. The pressure to meet contract deadlines was severe during the war. I've heard stories from more than one person who worked on the lines about aircraft radios like the ARC-5, SCR-522 etc. being shipped out the door and installed in planes without even being tested. They were probably tested in a rudimentary way after installation, but nothing like we would expect from a factory-certified unit. I would be very surprised if the same thing didn't happen at tube factories. The poor quality of large numbers of 807s made in those years may attest to that.
