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.
