Student Prince

1968 Williams EM Student Prince

First repairs on the Student Prince

Since its purchase last November, the Student Prince didn't remain unattended: it first went through a series of checks, following as usual the neat tips of Pinrepair on this topic:

  • Transformer ok
  • Check of all coils (measuring their resistance)
  • Visual check of all switches
  • Cleanup of the stepper units

After an initial power up, new problems appeared:

  • The Game Over Relay remained permanently energized. Problem solved by readjusting the control switch for this relay.
