ABSTRACT:
A modular frame assembly for a stereo system component such as an amplifier has a pair of rectangular side panels, a rectangular front panel and a rectangular back panel all removably connected to one another to form a rectangular frame structure. Heavy electrical circuit elements such as transformers and large capacitors are attached to the side panels of the frame assembly, while temperature sensitive circuit elements are mounted to an auxiliary structural member connected to the front and back panels thereof. The auxiliary structural member is aligned with air flow apertures in the front panel and the back panel and preferably consists at least in part of heat conductive material in contact with the temperature sensitive circuit elements. The bottom panel and a top panel of the frame assembly are connected to the rectangular assembly by self locking screws. In a stereo sound system the circuit elements associated with one channel are mounted to the frame assembly in an arrangement mirroring the arrangement on the frame assembly of the circuit elements of the other channel.
