Solid state transmitters are notoriously finicky about matching to the

to bear that out.
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.
