Sigur nu este vorba de AS2050? Vezi topicul cu scheme de amplificatoare audio.

Imi cer scuze, daca nu m-am exprimat suficient clar,intrebam daca pe ambele canale lipsesc piese cu acelasi rol si nu puteti obtine informatia despre piesele lipsa, prin compararea celor doua canale.

SAS 560s,este un comutator senzorial,despre el nu aveti date?
