[AMPS] Euro Sub For Eimac 3CX800A7

[W6NQ]

FYI--
Svetlana is still building the 3CX800A7 tube.
It has not been dropped from their product list.
Main difficulty, Russian plant still using capacity to build
whatever they can, often not on the U.S. "want list".
Also, some delay encountered with changeover of factory
export agreements.
Svetlana Electron Devices / Huntsville, AL., has been replaced
by PM of America.
I have been advised that some 3CX800A7 will be entering
U.S. this month.  Readily available quantities will be limited,
and several OEM's have significant orders on file.
General availability should improve by Summer.
73,  Merit  W6NQ
