Ever have a Bally/Williams system 11 game where the volume would not go below a certain level? Even with the control turned all the way down, the volume was still too loud. Well, the factory wired a resistor in series with the shield wire to the volume control. The cure is to bypass that resistor. I've got some pictures from inside my friend's Gameshow pinball which we just brought in from the route. The resistor connected to the volume control is a 47 ohm quarter watt which gets removed.
I have a "before" picture showing how the factory wired the resistor to the volume control which prevents the volume from going all the way down. The "after" picture shows the shield wire which formerly went to the 47 ohm resistor is now connected to bottom terminal of the volume control. This allows you to have full range of the volume control and can turn the volume all the way down if desired.
The cabinet wiring diagram page of the Gameshow manual does NOT show this resistor. However, the cabinet wiring diagram page of the Elvira manual does.
