The power supply is a modular design. The two major reasons for doing it this way are to allow replacement of selected parts and to allow reconfiguration. The replacement of parts may be needed because the experiments may burn up the transformers or because other transformers may be needed. It is also to allow alternator experiments to be done.
There are several alternator experiments to be tried. One of them is to remove the magnetic shunt ring from the rotor. That will cause a stronger magnetic field to be produced. Another variation is to grind the rotor pole faces to match the stator poles. By design they are large triangles. The new shape would be narrow bars. The result is expected to be a higher output voltage at a lower speed.
The output from the power supply comes from a miniature HV tower. It is made from coat hanger with an orange plexiglass bar across the top. The plexiglass bar holds two coax splicers to make connections to. This will allow the shields of the coax lines to be used as large area conductors or to be connected together for a high capacitance line. One experiment calls for having a glass capacitor in parallel to the transformers with dual spark gaps connecting them to the coax lines. Other experiments call for having capacitors in series with the output to prevent transformer burn out on heavy loads.
