Note you can drive your boards from a DC voltage as is, with no modification needed whatsoever. The bridge recitifier now acts as a safety, it makes the power inputs unipolar which is a neat little feature.

This means you can sit back and experiment with external DC power supplies to your hearts content until you find something that works for you.
