Got any pictures of the unit or the model number? I could try to see if I can dig up a service manual for it. Also any blown fuses? some of my older audio equipment had different fuses for different functions.
Model number is SC 2307B. I will upload a picture at 12:00 because that's when I finish school. I think a capacitor is blown inside because when it died 11 years ago, it smelled like smoke. When I opened it, I saw a 2200 microfarad cap that looked like it had leaked.
