Gottlieb's Player Unit - Friend or Foe? (under construction...)
Not for the first time have we worked on the Player Unit. A great design by Gottlieb, it simplifies substantially the workings of a 4 player game. One of the main problems with this unit has to do with adjustments. Our first picture shows the PU in the Game Over - Fourth Player - 5th Ball.

Here we have the PU after a RESET - the wiper disc is now set to Player 1 - 1st Ball.
Backside of the unit...
Here we have the 1st player cam lifting the 1st Player switch stack
Note 3rd cam has raised the 3rd player switchs
4th Player switch stack: contacts open
4th Player switch stack: contacts closed (on top of cam)
Here is the system relaxed.
Here is the plunger bottomed in the coil - note the stop bracket just above the arm.
Take a close look at how the linkages fit - this is with the plunger bottomed in the coil
