large vacuum tubes

["Tesla list" <tesla-at-pupman-dot-com>]

Anyone on the list have a few medium to large non-working vacuum tubes they 
wish to sell?

The transconductance can be bad as long as the filiment lights up.  I'm 
making an exhibit which illustrates the progression from vac. tubes 
(excessive wasted heat) to transistors to integrated circuits.

Please advise off list if you have tubes with prices --- I need a total of 
4 or 5 tubes.
