Thanks everyone for all the kind comments.

The amp will, most probably, be solid state. My ham radio amp has a pair of Eimac 3CX800A7s in it. Each tube is rated at 800 watts OUTPUT all day long. Think that is enough tubes for me.

In all seriousness, I'm going to wait until after I get a chance to use the 703 for a while before I decide how many channels, what power, and what brand.
