What I really do not like is the time delay for filament heating. I have
several "instant on" 811,572,3-500z amps, but I really like the 3cx1500 amps I
have. There is a 2-3 min delay but the amps loaf at legal limit. We Engineer
types know that electronics is full of compromises

I think that's what I want is no tune band switching and tubes would be
fine with that . John kb2huk
