I was given a Henry Kloss 88cd with a weak left speaker channel today. The subwoofer is OK. The right channel is normal. I tested both speakers and they function normally. I checked all of the mechanical connections and they seemed OK. I don't see any visable board damage. I took pictures of the components as I disassembled the radio in case anybody would like to see the innards of a Henry Kloss 88cd. Any idea where to start. I don't have a wiring diagram, but I can trace back to the audio board.
