Defect : Sunet slab distorsionat , zgomote in difuzoare la pornirea sursei . Circuitul integrat se incalzeste .

Cauza : Bucla de masa - probabil o greseala de proiectare a cablajului . Posibil , in functie de dispersia de parametri a CI aceasta autooscilatie sa nu se manifeste . Precizez ca marirea capacitatii de filtrare de pe alimentare (C822 , 470µF/35V) nu da rezultate .

Remediere : conectarea unui condensator de 220µF/35V intre terminalul cald R814 si punctul notat TP-GND (in imaginea atasata) . Nu uitati rigidizarea componentei atasate cu plastic sau chit siliconic .

Cablaj
