from the sound of that. First thing I would do is replace every elec. cap on that board along with the tants 1uf and 10 uf with 35 or 50 v parts and see from there. AMAZING what replacing all of those does for sound.
Also check for the heat transfer paste on the AMP chip or it will get hot and sound just like this. And check for dc voltage at the speakers. there should be none. If there is the caps are bad feeding the LM1875 . Caps C46-C47 (1 mfd Tant), C20 (10 mfd tant), C22 (22 mfd), C23 (.22 mfd)
