Have a Philco 841.205 Turntable CD Shelf Unit that was given to me. It looks very nice but several wires have been pulled from their locations. I need an electrical schematic to find out where the loose wires should be attached. Is there a schematic available? I have tried to find a service manual and none seems to be available. Is there another Philco product with the same electrical schematic? Thank you for your time and attention to this matter. Ed
