in acea schema exista doar un releu si doua punti redresoare  in amplif am doua relee o singura punte si alte circuite integrate din lipsa de timp

din lipsa de timp ,si pt a nu umbla orbeste fara schema am trimis acest amplificator la un atelier de reparatii .amplificatorul a fost reparat si functioneaza foarte bine .amplificatorul nu distorsioneaza indiferent de volum iar putometrele nu produc zgomote.l-am desfacut iar defectul a fost se pare in parte de preamplificare.toate bune si la locul lor.  pina cind am observat ca totusi degaja ceva caldura chiar si la volum mic se incalzeste puntea rezresoare dsfb20  se incalzesc foarte tare 4 rezistente linga puntea redresoare r1119,r120,r121,r122 si prefinali audio sa1535,sc3944

ce pot sa fac sa reduc aceasa disipatie de caldura.oare japonezi au facut aceste amplificatoare sa mearga asa fierbinti?
