------------------------- ERRATA ------------------------- Subwoofer/Bridge Adaptor for 12V (March 1996): Unfortunately, electrolytic capacitors C7 and C9 are shown with the wrong orientation on the component overlay diagram on page 76. When correctly installed, the positive lead of C9 should connect to pin 3 of IC2, while that of C7 must be connected to pin 8 of IC2. Also, 12V DC input leads are transposed in the overlay. The negative connection is towards the top of the diagram, while the positive lead is the lower of the two, as indicated by the '+' marking on the copper side of the PCB. -----------------------------------------------------------
