Marantz PM-64 Integrated Amp Repair - One Channel No Speaker Output



Published
This is a repair video for a Marantz PM-64 integrated amplifier. I found it was very effective by using the signal tracing tools which include a signal generator with an oscilloscope to trace signal path. The purpose of signal tracing is to locate the defective stage of a malfunctioning amplifier as efficiently as possible. Once the defective stage is determined, then it will be able to isolate the defective individual component or wiring connection for repair. The final finding of this unit was a defective speaker relay. Hope this video will provides some info. to other DIY fans when they encounter the same issue as I had.
