Circuit Design Considerations:
The Wingfoot 813 amplifier power supply was designed and built partly by Jim Trutko, W8EXI, and me. The chassis work, transformer and choke mounting, and most of the wiring was done by Jim. I am responsible for critical design and safety changes, the front panel labeling, repairs, all of the new rectifiers, and all of the new filter capacitors and bleeder resistors. The power supply was primarily designed to go with the Wingfoot 813 amplifier, but it was also designed to be versitile and to perhaps be used with other amplifiers. As such a variety of output voltages are available simply by changing switches on the front panel. Nominal output of the power supply is 2240 volts DC at about 160 mA, 450 volts DC at about 45 mA, and up to -150 volts DC at about 30 mA.
