echivalent 2SD1189


Recommended Posts

S.O.S. Sunt impatimit dupa vechituri hi-fi pe banda. Am mare nevoie de un tranzistor NPN 2SD1189 sau D1189 sau macar un sfat despre echivalenta lui. Asista un motor de 12V... intr-un casetofon din 1983. S-a ars motorul si dupa inlocuirea lui cu unul identic nu mai porneste capestanul iar in loc de 12V am 11V dar cand comand play tensiunea scade la 2,3V!!! si bineanteles nu pleaca capestanul. comenzile merg perfect. Vre-un sfat sau ajutor?
