Sorry, my english is bad, but I'm learning:D
Amp using idea from Kemp's paper.
Main idea -UcD based amp add integrator - we obtain low distortion.
I draw a full sheme later.

Another amp used integrator. Sheme and PCB. RU forum.

...seeing your design and also the vegalab forum, I feel that knowing the russian language would enable me to read threads with pretty valuable content...

Gerbers?
Not needed from my side. All relevant layout information is visible in your pictures. And when building, then I always love to roll my own designs.
I am more interested in the schematic + design considerations behind.
Also in chosen component values + why exactly these values had been chosen, while often multiple other parametrizations would be possible as well....

But I do not want to push you to publish things that you prefer to keep with you.
Basically it is clear how a marriage of Abletec and the Kemp anti saturation circuit or even other anti saturation circuits will look. Inspiring topic.
It is up to you to publish more or keep it with you.
 
This sematic diagram - simple idea from Kemp paper.
Abletec even easier.

...true... mixed up some connections in my brain, when I looked at your schematic the first time.
Nice way of summing the integrating gain to the UcD.
Better / less demanding for the OP amps compared than feeding the entire UcD feedback through a PI or PI².


How about your other amp, the one which uses the Abletec idea?
