Load circuit for testing dc power supplies adjusted without momentary interruptions typical of rheostat loads. Load current passes through power transistor and fixed resistor instead of wire-wound rheostat. In new circuit potentiometer used to adjust bias of power transistor and thereby adjust load. Components are standard, commercially available parts, mounted on transistor heat sink, forming compact package.
