tubes age 242
Astonished (and very suspicious of a misunderstanding), I Googled and found
a couple of references to this report as well as the AP article here:
http://www.sltrib.com/csp/cms/sites/sltrib/pages/printerfriendly.csp?id=5320
6814
All the vintage boatanchor lists I monitor have been quiet on this subject.
Maybe, I thought, I'm the only ham who doesn't know this "secret". God, I hate
being ignorant! Another reference to supplement this information is this report:
"Best
Export Markets for U.S. Electronic Components, 2010". On this website:
http://static.globaltrade.net/files/pdf/20101216032232.pdf
This report appears to be a partial source of export information for the "vacuum
tube" category named: HS 8540: This category is defined as including:
Thermionic, Cold Cathode or Photocathode Tubes (Vacuum, Vapor 3 or Gas
Filled Tubes, Cathode-Ray Tubes, Television Camera Tubes, etc.). "Vacuum
Tubes" were also in the top five exports in 2010, 2009, 2008, 2007 and 2006!
To those of you who know something about current vacuum tube
manufacturing, could you please enlighten me as to what it is, exactly, that we
are exporting that are called "Vacuum Tubes"?

largest US export in 2011!!??
Sure the old "major" manufacturers are gone (RCA, Sylvania, Tung-Sol, GE,
etc.) but that doesn't put the US "out of the business" making "common" tubes...
but think Industrial, broadcast and other communications. Look up companies
like
CPI (Communications & Power Industries) - the largest manufacturer and
rebuilder of electron tubes in the U.S. CPI owns Eimac, Econo and Beverly
Microwave systems. Look up companies like Richardson Electronics and/or
Westrex. These smaller companies specialize in high value tubes (such as WE
330Bs and such) but still contribute to the US's output of tubes. Then there are
places like Antique Electronics in Tempe, AZ - with a inventory of hundreds of
thousands of tubes (at one time more than a million!). They sell all over the
world... which also "counts"...
