I bought a used yamaha active subwoofer for my home theater, and found that one of the circuit boards inside was missing. I can't find an exact replacement for it, so I was hoping someone could either tell me how to wire it up without one or where I might find a similar style circuit board I could use as a replacement.
Two wires went from the missing board to the power switch and another two went to the amplifier.
