I wonder why?
The patent I was referring to was in the public domain since:-
2,791,646
ELECTRICAL SYSTEM FOR ULTRALINEAR
AMPLIFIER
Herbert I. Keroes, Philadelphia, Pa.
Application October 26, 1955, Serial No. 542,825
And is available from patentimages.storage.googleapis.com
So here is the corrected schematic again using the principles outlined.
