 Certainly I can see one of my newer rigs start to fold back at 2:1.
 
 What are the practical limitations of the Tube finals apparent 
 flexibility?
 
 Is it safe to compare the load, plate, and drive controls to some of the 
 functions of a tuner? (possible real dumb question)

Most quality built amps will cover 2-30mhz, they only need the proper 
filters behind 'em to keep 'em clean, and of course, you exciter needs 
to put out a clean sig.
Motorola has a great circuit using four 250W transistors to get you a 
kilo.  It can be found on the web.
There are scores of tech papers by motorola on 100W to 1K and beyond 
amps, a little research on the web should discover them.
