Hey, I just had a thought,
tell me if this will work:
    Take a high power mosfet and operate it as a class C amplifier
    driven by a 60Hz oscilator.  Run the output through a tank tuned
    to 60Hz.  The inductor in the LC circuit is the primary of a
    step-up transformer which takes your resulting sine wave to
    line level.

    Obviously, inductive loads on the output will effect the 
    inductance of the Lc circuit, and cause some change in
    frequency....I don't know how that would be dealt with.....
