4.8 Sound problems
System 11 games are known to have some amount of hum. An easy thing to test is to make sure all boards are secured tightly with all screws. This will insure the boards have a proper ground.
Another cause of hum could by an inconsistent +5 volts from the power driver board. An indicator of this being the cause of your hum would be the game occasionally resetting as well. Replacing caps C8 and C10 on the power board may fix this issue.
4.9 Flipper problems
4.10 Pop bumper problems
