But seriously, I can't make that circuit work for some reason.
Have you tried yourself to simulate it?
Did you succeded?

I just tried all 4 combinations for the 2 input generators, but it doesn't seem to work.

There was a guy, i think his avatar is Elso Quack, that worked with this circuit.
I think he has his own blogg now so you have to find him.

I would make it like a two stage.. first stage with the high-cut part of riaa between the legs...then folded over in the opamp.. with a local feedback there making the base part active.

You generators are canceling... so both legs are seeing the same signal. need to phaseshift one 180 degrees.

Interesting concept.
Otherwise is it possible top create out of this a differential folded cascode with transimpendance RIAA? something to think about.
If I pass the hump to simulate the plain scheme I can try to work that around.


For the generators, they are out of phase.
