During the repair

 Energy was adjusted until beam was found o This was done for all energies

 Since running at maximum deflection current o => ~36 MeV for all electron beams

 Instead of finding the defect (short-circuited) transistor and restoring the correct deflection current in the bending magnet

 To do this adjustment o energy selection had to be switched to “manual mode”

 By doing so, the energy selection from the control panel was partly disabled
