Looks OK to me. It's configured as a series common mode stopper.
What's the problem?
Will this design eliminate ground loop problems? My concept of baluns was that
they isolated the two ends by placing them on opposite windings of a
transformer. I am no expert, which is why I asked.
That is a different thing. You need a transformer to kill a ground
loop entirely, but yes, provided there is enough inductance in the
coils this will still make a good job of getting rid of hum from a
ground loop.
The downside of the transformer method is that lower bass response is
usually somewhat compromised.
