celelelte tensiuni pe tub cum sunt....grila 2 si catozii...tz final e fierbinte?....verificati condensatorii electrolitici indeosebi cei de 33...47 micro la 160 volti si 10 micro la 250 volti....daca tz final e excesiv de fierbinte inlocuiti condensatorul de intoarcere cel aflat intre colectorul si emitorul acestuia
