  • If pressing start button results in soft sound repeated three times "dugga dugga dugga" the machine can not find both balls. One may be stuck/hiding in the playing area or the limit switches that detect the balls near the launcher may be dirty or damaged. It could also be one of the fuses.
  • Powers on but won't feed balls? Check fuses in top cabinet. Front 'glass' lifts up and out, panel swings to the left exposing electrics.
  • Sound volume control pot/knob is on the inside, left wall, about 12" in from the front door.
  • TILT: The tilt switch is a metal rod hanging inside a round hole in a piece of sheetmetal on the left side wall just inside the door. It may be jammed to one side by the manuals or other contents of the machine.
  • Please add more problems and solutions as time goes on!

To do


  • Diagnose fuse blowing problem
    • Likely culprit: bad solenoid on jet bumper (already disassembled - discoloured)
  • Replace left flipper solenoid
    • This is the cause of the left flipper sticking on the down-stroke, and the repeated blowing of at least one fuse.
    • Order new solenoid
  • Replace all rubber bumpers
    • Order new bumpers
  • Realign flippers
    • They keep getting out of alignment no matter how much they are tightened. Maybe threadlocker would help?
  • Descale copper contacts
    • Better current flow = better power from flippers
    • Ian did one in Feb 2016.
    • Consider replacing with a different type of switches
  • [Optional] Replace lights with LED equivalents/rewire motherboard to work with LEDs
    • Rutger wants to do this pretty much immediately (as of Feb 2016).
    • Frollard is not so optimistic, because the existing matrix depends on the incandescent bulbs' resistance, making LED replacement complicated and likely not at all power-saving.
  • Resolder top front speaker wires
    • Only internal speaker works; top disconnected
  • Find replacement coin rejector
    • Player 2 quarter slot rejector missing


  • Redo exterior paint job; replace decals on side
    • Repaint?
    • Vinyl decal?
    • Image original artwork
    • Vectorize artwork
    • Sand down to wood
    • Prime and seal
    • Reapply artwork
