BX63 replacement?

[Titanium Dome]

Thanks for the link, Lancer. Based on that, I don't need the Soundcraftsmen bridging device.

Then this is what I plan to do.

A long shot here - need some help. I am trying to build a pair of the filters shown in post #10 on this thread by "4341B", using TL072's. Trouble is, I need to have it work with balanced inputs and balanced outputs, and have no idea how to do that . Can anyone provide a clue how to modify this circuit for balanced ins/outs?

Many thanks in advance!

You could add a Balanced Line Receiver chip before the first TL072 and a Balanced Line Driver chip after the second TL072.

Links to some very fine balanced line chips:
