No, none of them, sorry.

It was a 3 transistor version, with feedback from output to input (470R). A kind of compound transistor with feedback.

The output had a 470R resistor to Vee and someone suggested to replace it with a current source....

The thread were only with few answers, perhaps 5-7 replies...
