RE: Hooked on mono...







You could use a bridging mixer.
I used it with 2x UTC A-20 transformers and it worked a treat. The RC comp branch was not required in this case, configured for 'complete null' test it cancelled everything.

"You should file away that bridging mixer (distinct from a balanced mixer) circuit, I don't see
it anywhere when I search around. Everyone just resistor bridges now which is invalid from a
CMRR standpoint (just like op amp 'balanced' input transformer-less studio gear).
The CT of the balanced winding can be grounded making the mixer only need one input
transformer (or an actual balanced input).
As in using equal value resistors from R(+) to both L(+) and L(-) which leaves you taking
off the monoaural signal between R(+) and L(-). Anything you connect to one branch, you
have to connect the same to the other even if you don't use it."
