You shouldn’t take anything unless you know what it is, lest you end up with pieces from a radiography machine in your home. What looks like a weird piece of metal may kill you and you won’t feel it happening.

It’s a vintage electronic component from before the invention of transistors. Previously they were used in many applications, from radio sets to the first computers. Today their only application is guitar amps where the noisy analog signal they provide makes the sound. Audiophiles claim they can hear the difference between manufacturers of tubes of the same specifications.
As production of vacuum tubes has mostly ceased there is a lot of fetishism for vintage tubes and unused old tubes are sold for significant sums.
