@Felthry unplug it first
@yaodema there's still actual metallic beryllium in there! aka the stuff that causes the incurable, invariably fatal lung disease berylliosis
@yaodema vacuum tubes are generally fascinating but cavity magnetrons, travelling wave tubes, and beam tetrodes are some of the best
also the krytron is pretty neat but that's mostly because of things unrelated to the krytron itself, just the history of it and how it's illegal
@Felthry they're some of the weirdest vacuum tube tech in existence and most people don't even know that's what they are.
