The line I've always heard is that it's the useage of the tube that causes it to degrade. Keep in mind that there are antique radios with tubes that are fifty years old that still work--at least enough to prove that Grandma's 1933 Philco can tune in the glories of AM talk radio. (I wonder what would Grandma think of some of the things they talk about on talk radio?)
