I am in desperate need of information on how to find schematics for this EQ or someone who has parts or knows how to repair these units. There appears to be no hope for getting in touch with the manufacturer, I have tried the all of the available contact info I have as well as what I found online (which was the same) without success. I have found schematics for a version of the main PCB, but it is the daughter op-amp board that appears to be the problem. These are very expensive paper weights at the moment. Help me recording.org, help me. You're my only hope!
