La acest sasiu am o problema careia nu  gasesc rezolvarea, am scurt pe circuit finalulu de linii intre C si E, tranzistor dat afara masurat ok.Scurtul e in circuit, am verificat diode, rezistente , tranzistori, condensatori totul ok.Am citit tot ce am gasit despre acest sasiu s nici unul dn defectele intalnite pana acum nu se pupa cu ce am eu.
