Filtering the AC noise is what will provide a black background. You can do this with adding an AC filter choke to most components.

@redwoodaudio google ac filter chokes - many audio manufacturers use them - in the old days Counterpoint used them. Hammond makes them and so does Plitron. In some equipment you can install a choke where the AC lines come into a unit, etc. Peter |
