Something maybe of interest to those who like modern technology but are 
nostalgic for big glass tubes. I've just seen a press release from Cree, 
announcing that they are sampling a new Silicon Carbide device for 2GHz cell 
basestation use. I believe that others (Westinghouse?) have looked at SiC for 
UHF TV as well. As best I remember, SiC can work at junction temperatures up 
to around 650 degC, so you could have solid state, and a dull red glow at the 
same time!
