<<Hi Jerry,
If you only need 100 watts, I'd search for a DX-100, Viking 2 or Viking 1.
My initial preference would be for the V 1.

I second that. The Valiant probably has the worst audio section of any of
the classic plate modulated AM ham rigs, except maybe for the Apache. At
least Apache audio can be cleaned up and I have heard a few that sounded
pretty good. About the only way to get a Valiant to sound good and make
near 100% modulation is to completely re-work the audio section, or use an
outboard speech amplifier and modulator altogether. The Valiant modulation
transformer has too much step-down, 6146s make notoriously bad modulator
tubes and the speech amplifier/driver stages are poorly designed.
