Hi:

I've realized that one of the channels of this amplifier has no proper sound.


This is the signal at the speakers output.

As long as the audio coming in to the amplifier board (blue) looks ok although with some noise due to the wire, I think that there's nothing to look at the preamp section.




Now, I could start looking at components to see whether I find the guilty one.......but I would rather prefer to ask for advice. Here there is the amp. schema. Which points would you check with the oscilloscope to gather...
