Although the power suppies were not specified as part of this project,
they had to be constructed for use in our home-basement workshop. To
drive the audio control subsystem, a +/-15volt
power supply was constructed (Schematic: DWG# 2002-21-E261). For the high
voltage generator, the supply voltage was unknown, but was expected to be
around a few hundred volts, so a variable power supply was constructed to
meet nearly any need (Schematic: DWG# 2002-21-E262). It is variable from
0 volts to ~360 volts at up to ~0.3A. These schematics are shown below:
