To do

Functional

• 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

Formal

• 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
