vad ca poza este de pe alt forum , ai gasit rezistenta arsa?
dupa cum vad este legata cu dioda zener , este un fel de stabilizator din poza vad ca scrie 8R75 adica in jur de 9 ohmi, in funcie de dioda zener se poate calcula rezistenta , condesatorul , nu e critic , in alte scheme este de80 -100n

verifica si dioda zener , daca e scurtcircuitata scoate-o si fa proba la o sursa de alimentare , cred ca dioda zener este de 12V , integratul se alimenteaza pina la 15V
