I would recommend for you to refer those application notes and you can find some other new generation audio op-amps on TI.com, such as OPA1656…
Yes Ivan, thank you, that's the resistor. The .PDF link is a different application sheet than what I was looking at (TIPD186) and did not have all of that information/breakdown of the circuit.-Keith
ser,
The LM1036 was released over 20 years ago. It is no longer available.
Here are two starting points to get the same function.
OPA4228 datasheet, see section 8.1.5 Three-Band Active Tone Control (Bass, Midrange, and Treble)

Hello Olivier,
Thank you for providing the requested information. I don't see any issues with the schematic.
In the bottom two scope captures showing the input, it's clear than an offset of approximately -1.3V is present, even at DC. The output shows…
