Greetings ALL,

        Dose any one have any information on a Radio City Products, Model
777A Signal Tracer. I was given one and have got it working, but the
Audio output tube's Markings have been wiped off. I would like to find a
manual, or even a schematic. Any and all help would be greatly
appreciated. Thank You.
