Exclamation looking for a bridging adapter for power amplifier

I have looked and only found how to build one, still have never done anything like that..so is there anywhere I could buy one from...or someone have one for sale??? need to make one of my onkyo M504 mono ( used as a center channel amp)..its a common ground amp..so as long as the ohms dont get too low..it should work

This is really a very simple thing to do. You can use a transformer or a very basic op-amp circuit to invert the signal to one channel.

I'm swamped with wiith other things right now, but if you really have no other options I'd be willing to throw something together. Might take me a little while though.

Oh, well then you have much to learn.

Do you need it for a single input or both L and R?

You can use an audio transformer to produce the out of phase signal.

Absolutely, the problem is where to get decent quality transformers inexpensively?
