I had no idea that 811's and 807's had mercury in them!! 866's yes.. but
807's???

Does anyone have a good procedure for discarding 'blown'

I have a few 811, 817, and 807s (some good, some not), and an un-id
(think 807-size) unit that has a pool of mercury in it as well as a
nice splatter pattern inside the glass. The glass and the base are in
decent shape (no cracks) so it makes an interesting conversation piece
("hey, hook it up on a tester and lets see what happens!" are,
unfortunatley, common...) but I am concerned about safe disposal of
the sucker.

Find a toxic dump, a local ham who collects them?? (I won't ship the
blown tube).

Thanks,

They don't. Only mercury vapor rectifiers have mercury in them.

811s and other tubes with thoriated-tungsten filaments have thorium in them,
which is slightly radioactive.
