Speaking of AM Transmitters, does anyone have a source for plans to build an AM Transmitter for 75 meters in the 15-25 watt range?Thanks.

I have over the years built several low power AM transmitters. I would like 
to build something a little bigger say in the 400-500 watt plate modulated. 
I have been kicking around the idea of using one of the solid state 
amplifiers made for car audio driving a reverse connected audio transformer. 
I have seen these audio output transformers available in the 200 watt range. 
I understand that the RF output stage would have to be designed to fit the 
impedence of the output transformer.  Does this sound like it could be done?
