I'm 15 years old, and even I know that a leaky tube [in a radio] reduces
the sound quality, the loudness (depending if it's an amp tube or not),
reduces the life of the tube, possibly can cause a short in the tube, and
can possibly weaken other components. a leaky tube in a TV will
occasionally cause a bad (or no) picture.

I think the only reason that I know this is that I collect antique radios.
maybe I'm just odd...
