Hello Alan,
about six years ago I started talking with Charles Whitener that is the man behind the Western Electric tubes.
After talking with him several times on trade shows he invited me to see his production rooms, that durring that time were still in the original WE location in Kansas City/MO.
He has some of original WE machinery as well as upgraded modern tube making machinery; he designed a cathoporessis tunnel to make his cathode/filament for his 300B, very impressive.
Aside some of the WE stuff he has a bunch of other "vintage tube material", like glass bulbs made at Ruhrglass/Germany, plate material, tooling for making sockets, etc.
After our talks in KS he invited me to his "that time planed" new production place in Andrews/NC that I visited but we never came to a conclusion for making tubes due to his business ideas and practices.
To his accounts he is also somehow involved with SED in St. Petersburg, winged -C- tubes (formerly Svetlana). Last thing I hear that he moved his factory to Huntsville/AL.
He might make an O.K. 300B (in my opinion his new 300B are same as good or bad than the $50 EH 300B) but all his other plans to reissue KT88 as well as other "Power Tubes" failed/or maybe are just delayed to this point.
He is missing all vital machinery and knowledge to make good studio useable (pre-amp) tubes, he also claims that he has the RCA as well as the GEC name (only for electron tubes).
Best regards,
