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

Motorola has a great circuit using four 250W transistors to get you a

There are scores of tech papers by motorola on 100W to 1K and beyond
amps, a little research on the web should discover them.
