Since all the affected functions/modules reside directly on the KLM-128 board (the patchbay board) I believe that at least one of the supply voltages is missing (or misbehaving) directly on this board. So my first attempt would be measuring the supply voltages at various points. I'm not completely sure but I think the supply enters KLM-128 on connector H4. -- Malte Rogacki gacki@... ---------------------------------------------------------------------------- "Don't forget to TURN ON THE SYNTHESIZER.
