Hello, I am helping a friend who is repairing his TV. He is 43 and new in this hobby. Had a 1968 Hitachi models TWR1800, equipped with compactrons. He needs the schematic manual since many pieces do not see the value. I have searched the Beitman manuals, without result. Maybe someone has it. Thank you so much. Gustavo.
