I stumbled across this on YouTube. It gives a glimpse of the complexity of vacuum tube manufacturing. The vacuum tube portion begins at 9:22. Note the device at 9:48. It is tapping the tubes with a cork. It looks like a pretty severe test to me, similar to how I test for microphonics. Well maybe I don't tap quite that hard. Also note the testing fixture at 11:12. I believe each one of those light bulbs is in series with a tube and used as a current limiter and indicator of a short. Any of you who do repair work should recognize that.
This is an RCA factory but all of the major manufacturers were similar. I can see why NOS tubes last so long and sound so good compared to current ones. I seriously doubt that Russian and Chinese manufacturing is anything like this.

GuitarZ: So, I cranked up the privacy protection on my browsers, facebook, etc. I have to say I miss the music ads and such. I really don't need ads for watches and other random stuff. Maybe the internet knowing me isn't such a bad thing.

The Bad Poodle: This may be a truism... when you work in a corporate structure, the worst decisions always come from the top.

GuitarZ: Reminds me of buying my Honda. When they tried to sell me the maintenance package, I said "Is your car not reliable?" Long story short my wife teamed up with the sales lady to buy the maint package. Never again!
