Question about John Roberts Parametric EQ

[nachvai_89]

Hi everyone, first post here.
I want to make John Roberts Parametric EQ my first DIY proyect.
(This one

What I wanted to know is how to add balanced inputs and outputs to the circuits.

Thanks in advance

This is what I have in mind.

I added a circuit schematic, the SVF is not complete.

I added the balanced inputs and outputs from the Douglas Self book.

Do you think it will work?

Warm Regards

Do you want to use transformers or IC for de-balancing and balancing?

Electronically balanced outputs is easy with one SSL9K balancing board
