Hi, I've just repaired a KLM-367 board with battery leakage. Everything works fine except that the effects selector does nothing. It is definitively a problem of this KLM-367 board, as I put another working one board and the effects selector was doing fine. So I suppose it's a problem of the mux/demux circuit. Does anybody knows which IC in that board has to do with the effects mode knob?.
Thank you!
Regards.
