va salut! Va rog daca ma puteti ajuta cu ceva idei, pentru aceasta vechitura. Initial am gasit tz final linii in scurt, un D2539; neavand, am pus un BU508DF,am verificat +B=135v, cat scria si pe placa.( nu am gasit schema). A functionat 2 zile si s-a ars iar. Am pus D2539, am verificat iar condensatori,+B, a mers 20 min si s-a ars. Oare ce as putea sa mai fac??? Va multumesc

se pare ca l-am rezolvat, de vina erau cei 3 condensatori de 470p/1kv din colectorul tz; de asta se tot ardea tz final linii. Functioneaza de mai bine de 3 ore.
