sansui sm-3000 schematic

[felicia]

i dont know if i posted in the right place or not, but i have a sansui sm-3000 i acquired free because it makes a whirring noise when hooked up. i am thinking it has a bad cap or resister or noise blocker or something that is going to require a walkthrough and a multimeter. i am thinking also that this is an old amp because i cant find a schematic no where, just wondering if anyone has one or knows what the problem might be, thanks in advance.

should have put it in the amp discussion area ,but sounds like a loose or broken ground in the amp.is it a whining noise when the engine is on ?if so then thats the issue.get a hold of spooney on the forum here ,he could help you with the issue,he repair amps.
