Nu am cum sa reglez ca e imaginea cu linii si nu se vede nimic acum. Am incercat sa dau asa pe contrast dar nu se vede nimik. Am masurat condesatorii electrolitici si sunt buni. Mufa soclului tk a fost schimbata vad. Poate fi din bleder sau cum se cheama ansamblul de potentiometre focus si screen. MsTubul e Thosiba. Si eu cred ca e gata. Pubela il asteapta...

Desfa catozii in gol si masoara cat ai pe ei si atunci vei sti cum sta tubul.
