E clar ca ai bleederul de la trl defect.Il poti schimba(daca ai experienta)numai pe el,atentie cum izolezi conexiunile,acolo ai fit,bafta.

in momentul in care ii scade luminozitatea scade si tensiunea de screen la 40v.am dat potentiometrul la minim apoi am rotit catre maxim iar tensiunea crestea normal 100v ,200v pana se regla corespunzator.sa fie traful de vina sau o alta componenta?
