Tom, play -close- attention to John on this.  He used to run a 
home-brewed final, that he built that was link coupled, using a pair of 
304TH(or TL's, I can't remember - I've slept since then!)  @ One 
thousand watts DC input to the final, back when that was the legal limit.

Best of luck on your project, Tom, and your project, John.
