Thank you for the response. I did try a TLE2141 but the circuit did not peak detect and hold. I concur with FvM that there is a need for a "substantiated circuit design" and so called in an expert to do the architecture.
You are correct it was my mistake. Now, I exchanged the Input + to the #3 pin and #2 to the R2 10K.
The Output signal is still a flat line. A new CA3140 was inserted but there was no improvement.

This is the corrected Circuit Pin # and the revised breadboard that...
Further to the old discussion on https://www.edaboard.com/threads/298751/
I tried to use the first circuit illustrated. I have modified the drawing to illustrate the pins used and to show 9 Volts IN.
A 40 KHz signal input is giving no output, on the scope, which indicates a screw-up...
