Does any one know how I can get the schematics of Soundbridge Radio? I am trying to fix my radio that has dead left channel and distorted right channel and subwoofer. I did find some internal pictures of R1000 (https://fccid.net/pdf.php?id=613761). But I have not found its schematics except the one for PSU.

I have not seen schematics for the amplifiers, but take a look at this post.
