Riccardo Ottaviucci Posted March 19, 2023 Report Share Posted March 19, 2023 (edited) la tensione è più o meno corretta,credo che vadano in esaurimento col tempo. Spesso con una semplice pulizia riprendono abbastanza luminosità. Possono esserci anche degli elettrolitici esausti sulla linea del -33V Io li cambierei, C514,504,505,540 (qui lo schema completo) Edited March 19, 2023 by Riccardo Ottaviucci Link to comment Share on other sites More sharing options...
