hello
I found an amplifier marantz PM63 but no sounds
It seems to be clear, no burned composants and so on but no output
I want to test the different composants but i have no schematics in order to help me founding the roblem
If somebody got the schematics of this amplifier, it will be so glad to send it to me
thanks

Hi toirem.
Do not know if it is the same as in my pm66 but my output relay didn't pull.
This was due to a burned resistor in the supply for the protection circuitry. If you have a relay and don't hear any click on turn on then check the supply voltages, i think it was a +24 volt that was missing.
Do not know if this is a standard error, i think mine was caused by my daughter excessively turning on and off the amplifier.
The resistor didn't appear to be burned which was good in one way since i didn't have any schematic so i wouldn't know its value if it would have looked like a piece of coal.
