There was an article in Glass Audio, on how to build, I think it was called, a phase inverter. It was a inverter of some kind. It looked really simple, to construct, and it turned any stereo amp into mono. Glass Audio routinely sells back issues, so it would not be hard to find.So if you're deadset on going mono, that would be one way. I agree, though, that vertical bi-amping would be better. Once you get another amp, all you would need, would be more speaker cables.
Making Stereo amps into Mono
I have a Nakamichi PA-7, which is gathering dust. I am interested in either changing the power supply to a bigger, beefier one and or, getting another PA-7 and somehow have them both modified to make them MONOS. Is this a crazy idea or would I be better off getting real monoblocks for the price. I really like the sound of this old Pass designed amp, but I feel that there could be more power to be had. Has anyone done something like this?
