    Any idea how long a vacuum tube is supposed to last before it burns up? I'm working on 43 years...

    The filament is the part that is most likely to wear out, just like a light bulb, but it is much tougher than that in a light bulb. There are light bulbs out there that have lasted longer than that. You're just lucky.
