Re: LF: A transductor for power regulation?

I used a much smaller circuit but identical as an input attenuator for an experimental vlf transceiver and it worked very well. The control was obtained from the agc line. Definitely worth pursuing!1

Your circuit is a magnetic amplifier.

 

This book is useful.
