This is an older amplifier but still a great one. For some reason it powers up and all lights come on and everything works except for the output. Sometimes it will kick on after 5-10 mins and other times not for an hour. But unfortunately today it’s been well over two hours and I fear it won’t kick on again. Is there a way of checking relays or solenoids on it?

lowflyer17zz this " it will kick on after 5-10 mins" sounds like either a bad capacitor or IC issues. Not much of a SM but it does have the schematic for you to check out your circuitry Sansui 5050
