Info I got from another site:
i recently replaced the TA7136P in the phono section of a kenwood receiver. The difference is remarkable! wider sound stage and more detail.
I replaced two single op amps with 1 dual opamp. I had a OPA2604 on hand so I used that.
You could use:
NE 5532
OPA604 or OPA2604
Keep in mind that the TA7136P is in single in line package and the new parts come in DIP or even surface mount. So you will need to build a little pin-to-pin mapping or conversion.
TA7136P pins:
1. frequency comp
2. non-inverting input (+ input)
3. inverting input (- input)
4. V-
5. voltage comp
6. outout
7. V+
So for modern op amps you probably don't need to map pins 1 and 5.
Good luck
