The part that is ruggedized seems to be the filament.  Whereas the 
3-500Z/8008 filament is unsupported at the midpoint, and sometimes bends 
during parasitic visitation,  there must be some kind of a mid point 
support on the 3CX1200A7's filament helices that keep them from bending.

6x as much feedback C as a 3-500Z/8008.  (sic)   The improved version, 
the 3CX1200Z7, has 1/10th as much feedback.  Perhaps Mr. Rauch can tell 
us why the Ameritron AL-1200 has not switched to the new Z7 version?  


Cheers, Hank.
