GRTS, Galaxy has a model called 98VHP. It has 8 IRF520's as final section. Might want to take a look at that as well. Going to try a few other projects with IRF550's and IRF35X series. Anyone know how I can post a pic of this project?

Hmmmm.... the splitter and combiner look almost identical to what are in the TS units. Those cores have a very low permeability (u)

The plastic mounting screws on the mosfets will be a problem.
