Hi
As the text states C3 is for input lag compensation, which limits slew rate to
reduce high frequency intermodulation.

This amp design is crying out for some decent compensation design.
Problem was, ~40 years ago there was no LTSpice or any other readily available simulators. I think compensation design in those days was for all but a few very knowledgeable practitioners, a black art. You certainly would not comp an amp like that today. Some of the old JLH and Elektor designs also look decidedly pedestrian by todays standards in this regard.
