Still lots of old TV tubes around: repair shops kept large stocks  
around, and dealers grabbed them for pennies on the dollar as the  
shops closed up when the tube era ended. If you want to build tube  
stuff from scratch http://tubesandmore.com/ has lots of stuff: old  
tubes, current tubes, sockets, transformers, ...

In Japan, Tokyu Hands (a division of the Tokyu department store  
chain) sells tube amplifier kits.
