I must wonder why they would have mosfets on a graphics card!

Awesome work! I love HF SSTCs!

Forgive me if it is an oversight but where do you inject the audio in to your driver? A total wild guess to me looks like across the 1nF cap at the gate of the right-most 15N03L fet would be a good spot. I can't really follow anything to the right of the 14V input but the Green and Red sections look perfect to me though.
