Re: audio modulated SSTC - Rail Modulation

Dan, all, can anyone describe how a Plate Modulation
transformer is made? Would it be possible to make one?
Turns ratios, inductance, reactance? It seems the lower
voltage of the SSTC's may make it easyer than having to
work with the high voltage of a Tube's plate supply.
There are many nice designs for simple high power amps
(thanks to some great IC's).
