I need the circuit diagram. Becasue the amp is not booting up. I mean it does not allow the power to come in. The service man says that the unit is passing out some power in the speakers. Because the unit arrests such behaviours, it does not allow to take in the power at all. So the unit is not working. The service man said he needs the circuit diagram for repairing the unit. If anyone has it, may I have it. This would help me get back my unit.
