cum se arde siguranta ? instant la alimentare sau dupa ceva timp (1 sec sau mai mult ) daca pusca instant ai un scurt intre + si masa comuna , daca nu pusca instant ai ceva care se satureaza , si cel mai probabil un final . verifica finali sa nu fi inversat ceva , verifica cum ai pus diodele , vezi sa nu ai o lipitura rece sau niste pini lipiti la un loc din greseala .. eu am patit la un amp cu 2N3055 sam inversat C cu E la un final si pornea cu consum de 1 A si urca pana la 3,5 A si intra sursa in protectie , din ce-mi aduc aminte la kitu ala nu ai cum sa inversezi finali ca-s pe placa pe radiator..
