idle curiosity...

are any tubes being made in the USA now?
or anywhere besides China?

I would really like to get a spare set of 3-500Zs but I am not under 
the impression they are used in medical equipment.

since I am a 65yr old with self diagnosed ADD <G>, I have found it 
interesting that some trials are being run on RF anti tumor therapy in 
the Houston Med Ctr - at about 40m frequencies.    My oncologist at 
MDACC seems to think it is all foolishness but then, if it does not 
involve getting his patients into Pharm trials, he is not interested.

anyway, am still curious about where tubes are being made today.
My impression is that they are ALL Chinese and are rebranded Taylor, 
Svetlana, Marshall, whatever.  Hope that I am wrong.
