I'm wondering if you guys could help me out. My father's AR amplifier is not working properly, all of a sudden. The amp will work for about 20 min just fine when first turned on. After that, the volume drops significantly and the sound becomes distorted and staticky. This all happens much sooner if you turn the volume up high.
I don't live near my father, and he does not have any decent techs near him. So I can't take a look at the amp myself. Any ideas as to what could be wrong with the amp?
Also, I can't seem to find a schematic for this amp. Anyone have one, or know here I can get it?
I'd greatly appreciated the help!
I've attached a photo of what the amp looks like. Not my father's. Just some pics I found online. Seems there is no model number
