Va salut.problema e ca s-a oprit din senin .Atunci cand functiona la apasarea "mute" cuplau doua relee .Acum nu se mai aude sunetul specific cuplarii ,nici on, nici off.Pentru a gasi buba ,ar trebui sa merg pe + de la boxe?E O REGULA? etajul final e format din mai multe tranzistoare ,asta ma incurca.Si as mai avea o intrebare,legata de placile care au componente pe ambele fete.E foarte greu de scos o piesa.Exista ceva decapant specific pentru cazurile astea?
