Please help me find the smps600n400 and nc500 circuit diagram for repairing the marantz pm ki ruby ​​amplifier

I am also interested to order a Marantz Ki Rubi and become interested to know more details of this power supply issue and schematic.

Did you try to contact Marantz Technical Support with model and exact serial number?
