Good morning, Eddy.

Gee, my DX-100 works on 11 meters, you mean I can't use an 833A amp 
on 11 meters?  <ducking>

Just kidding, don't shoot me... :-)

I have several rice boxes around here and a Collins KWM-2A / 30L-1 
for 40 meters and higher, and I really don't anticipate using AM on 
those bands anyway, so I guess I'd be satisfied with something that 
works well on 160 and 80, and maybe 40... satisfied, that is, until 
I'm not... :-\
