WebAC Plug - The first part of the circuit is the AC plug. When we create a DC power supply, it creates DC voltage from the AC mains voltage from a wall outlet. To build a DC power supply, purchase a 3-prong AC plug. It can … WebThat's the filament power that goes to the front panel jacks. I didn't want to lose much voltage. The windings are rated for 7 or 8 amps - enough to start a fire, me thinks - so I protected them with some panel-mounted circuit breakers (the kind they use in airplanes). The two octal sockets closest to the power transformer are actually relays.
