@mckinneymike—I'm curious, who/what/where are these new vacuum tube production facilities? The Noritaki "nutube" thing is just a restricted special purpose curiosity product of virtually no use in hi-end audio, the RCH Labs startup recently died in a bankruptcy auction, and the Western Electric reissue trial is a small, limited, insider-use effort.
The existing public vacuum tube suppliers are all marginal, unmonitored profiteers located in China, Russia, and other obscure ex-Soviet block satellites, and wholly dependent on the guitar amplifier and "tube audiophile" market. There's no other receiving-type vacuum tube usage anywhere in the world, for any purpose.
Where are those "new and modernizing tube manufacturing facilities" that you cite?
