Gottlieb Futaba displays run on low voltage

The blue Futaba displays used by Gottlieb run on about 60 V, against about 190 V for Williams and Bally gas displays, so they last a very long time and fail less often.

System 80/80A displays run on about 60 V DC; switch the game off before unplugging or touching a display or its connector.
