Schematic diagram

[tonyrebeiro]

I have a KAM KXDR-1600 amplifier, which I purchased in 2010. Recently it has developed a problem on one channel. It started with crackling and finally stopped altogether. It looks like a faulty coupling capacitor. Can anyone give me some help on where this capacitor is on the smd board or please get me a copy of its schematic diagram, so that I can trace it myself. Thanks.

Can’t find a schematic diagram, but you can trace the audio signal back from the output with the multimeter,take photos and how do you have your “operation mode”set up.
Have you ever soldered or desoldered solder any electrical components on a PCB board?
If you have a oscilloscope that would be wonderful.
