Speaking of those external anode  power tubes, a friend just gave me a
couple of 8807 tubes.  Made by Burle, a company I had never heard of, but
they look about like a PL-172A sort of tube.  Well I downloaded a spec
sheet and these things have a rated plate dissipation of 15KW!  The 
filament alone takes about 1.5 KW.  And they require about 600cfm of air,
which is more than ten times what a 4CX1500A needs.

Anybody want to build a California kilowatt?  I've got just the tubes
for you.  Can't offer any help with the power supply, however.  You might
be better off trying to find a discarded TV transmitter and reworking
the tuned circuits.
