Hello, My Carver Knight Shadow sub has developed a nasty 60 Hz hum that I think may be a defective power supply filter capacitor. I desperately need a service manual or a schematic diagram to complete the repair. Please help me locate the service info if possible. Thank you, Dave
Yes, I did repair the hum problem that I had. The problem was an open electrolytic capacitor in the power supply circuit. I don't recall exactly which capacitor but it was not the large ones. I seem to remember the problem was a 20 - 30 mfd capacitor.
