Sziasztok!
A minap került hozzám egy PIONEER A80 erösitö, ami olyan furcsaságokat csinál, hogy ha benyomom a 15 Hz védelmet, akkor 3 másodperc után leáll, ha kikapcsolom, akkor pukkan a hangszoró egyet, és a muting gomb sem reagál. Meg lett egy alapzaja. Ezelött tökéletesen müködött. Valakinek nincs valami ötlete, hogy mi lehet a gond vele? Mérve a tranzisztorok jók, a kondik sem látszanak felpuposodva, feszültségek jók.
Sziasztok!
A problémám a következő átalakítottam egy TANNOY gyártmányú aktív erősítő panelt aktív sub panellá. Az áramkör tökéletesen működik párhuzamos üzemben megy a két darab LM3886-os IC viszont, egy két perc alatt tűz forró lesz. Szkóppal nem tapasztalok gerjedést. Vajon mi lehet még a probléma?
Szép napot mindenkinek.
