The main power supply unit provides a 42.5 VDC 24 ampere source. It is a
switch mode power supply unit. The output feeds the PA and the 24 Volt DC
power supply regulator. This in turn provides power for the drive amplifier. The
main power supply also has a 5 VDC output which feeds the control board.
