I have a Marconiphone VRC74DA early 50s tv/radio which seems to well, (it was restored with new capacitors before I aquired it, but as it runs for longer periods the picture becomes very hazey and out of focus unless i turn the brghness down, but then its too dim. Also the width is too wide with the width slider at minimum, and the height is too low on maximum hight range.

Any advice would be greatful. Also I dont have a circuit diagram, does anyone know where i can get one from?
