What does one do with old outdated audio equipment?

I'm honestly at a loss as what to do with my old equipment that's been sitting in my basement for a couple of years. There are: 2 citation 19 amps, a citation 17 pre and a set of jbl L 212 speakers. I havn't any use for them and cannot imagine anyone else having any use for them, they're soo old. Does anyone know of appropriate grave yards for these thing?
