[Amps] richardson? TSPA

[John T. M. Lyles]

The Amperex glass tubes sold by Richardson Electronics are made by 
Covimag in France. For example, their 3-500 and 4-400 sized tubes. 
While it does seem that REL has their fingers in a lot of vacuum tube 
manufacturers, there are still independent companies out there. You 
can still buy direct from CPI/Eimac and get engineering support - but 
not glass tubes anymore. Telefunken and Seimens planar tubes are 
owned by Thales now, and Brown Boveri is also. Thales does produce 
glass tubes, in the Thonon les Bains facility. I have seen them there 
numerous times, although they don't have a line of amateur power 
tubes anymore, mostly industrial/scientific and broadcast. They took 
on the klystron business of Philips too. E2V in UK still produces 
glass tubes, although again not amateur. If you are so inclinded to 
buy out tube manufacturing equipment, why not go to Triton in Easton, 
PA and resolve what happened to the Eimac 3-500Z and other originals.
