to start off I suck @ reading schematic.
So with that being said. I have a Battle Zone with no volume potentiometer and I would love to have sound.
not sure what size of potentiometer and how the wires go.
I have 4 wires coming out.
Thanks
Just as a quick reply off the top of my head. Atari used Rheostats for their volume controls. Basically its a potentiometer that has a higher wattage rating.
