This circuit is ideal for a power supply that enables the use of automotive power appliances on a workbench. Transceivers, amplifiers and other equipment can then be powered by the power grid. The regulator used is an uA723 which consists of a specific integrated for this function. The 2N3055 transistor that has the emitter on the 0.065 ohm resistor must be mounted on an excellent heat sink. The 0.065 ohm resistor should be a wire wound type.
