Do you still need you hk775 repaired? I have 16 of them...... yes 16 Harman Kardon hk775's. I have had 4 of them restored and use them in my current system. According to the serial # of the amp the schematics will be different and you need the right schematic for the right amp according to it's serial number. I have all of the schematics for all of the serial numbers. Which one do you need?
