I had some thoughts yesterday an drew this. Ignore the component values, obviously.
I'm not a big fan of transformers, but sometimes there is no other way to achieve some goals. I believe a good high ratio trafo and a low noise FET op-amp will get me there, so I'm trying to get maximum out of this approach.
This is an InAmp variation with servos and an input transformer. With precise op-amps the offset should be low enough for direct coupling to any equipment. A trafo, a double op-amp for the input stage and a quad op-amp for the servos and the output.
So, should I give it a try?
