Hi Diyguys !

I'm having a question here about a balance line receiver.

Here is my question.. I do have build a capi summing mixer (2aca), but I encounter some noise problem with it.. but only on L chan. not R.. wich is really weird.

I did it kind of ruffly, with no balanced line receivers.. Taking my hot signal from the balanced input, and linking the cold and the ground to ground.

So, in order to get it properly done, I was thinking to use  the schematic given by Peterson on his website (https://www.diyrecordingequipment.com/pages/balanced-input-output-assembly-guide)

Here is my question : I will build it with INA134, BUT :

With the same draw, can I use some Opamp (like Gar1731??)

My second choice would be to use some CAPI 2-Stage Line Amp, but I can't afford the 32 DOA now.. can I use an ic instead ? with the CAPI IC-DOA PCB maybe ?

Many thanks for your answers !
