Recommended Posts

Buna dimineata am acest amplificator l-am gasit cu primarul intrerupt.Are siguranta de temperatura,sper ca m-am exprimat bine,pe care am gasito intrerupta.si am mai gasit niste rezistente tip smd carbonizate R362,366si363 .nu stiu valuarea lor.Sunt situate intre releele de protectie spre iesire.Mentionez ca au fost folosite niste boxe mai mari decat putea el duce,din spusele propietarului.Nu am schema electrica.M-as bucura daca se poate sa ma ajutati cu valuarea acestor smd-uri.Va multumesc anticipat.

Se vede ca sunt la iesire. Probabil ca s-au dus finalii, consumul a fost mare si s-a intrerupt siguranta termica din traf:
