Grundig ST72-862 sortáp probléma
Sziasztok! Stabilan 165 volt a sortáp, nem tudom alacsonyabbra vinni, mert nem találom a hiba okát (SM szerint 142-nek kellene lennie). CUC2033 sasszi, és villámos volt. Most már műkszik, de lekapcsol. Az R61313-ra nem reagál, LM358, BC548B cserélve. Minden ellenállást és diódát jónak mérek, a kondikat is átnéztem ESR mérővel, látszólag minden hibátlan. Van erre valakinek ötlete? Üdv:Zoli
