They don't age by sitting on the shelf. They work just fine after sitting there. One of my other hobbies is Hammond Organs and I have plenty of vintage tubes that are still going strong. Doesn't matter if you use them and then leave them sit for a while either.
Now capacitors that is a whole different ball game.

What year were they made? I didn't think so. At least 3 of the 1930/1940's vintage TVs on display at the Early TV Museum in Hilliard, OH work (I turned them on). I'd think today one would have a hard time finding replacement picture tubes for them. BTW, I highly recommend the above as an additional activity before or after Dayton. Normally they're only open on the weekends, but if enough of us want to visit during the week (say, the Thursday before Dayton), I think they'll open for us. Bob NO6B
