  • Patent number: 4827375
    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.

  • Patent number: 4713629
    Abstract: The positive and negative outputs of an operational amplifier are employed to drive two oppositely phased current mirror circuits, which in turn drive oppositely phased power amplifier stages which drive the load directly without the use of an output transformer. Negative feedback is provided from the output to the operational amplifier to enhance flat response over the frequency range of interest. The oppositely phased power output stages are supplied by a power source which provides positive and negative supply voltages with reference to reference "ground". A plurality of capacitors are selectively connected as need be between the positive and negative voltage busses and ground to bypass spurious high frequency oscillations. A relatively high voltage output is achieved from the amplifier without exceeding the breakdown voltages of the transistors by employing a plurality of cascaded "Darlington" type circuits in the power amplifier.

  • Patent number: 4555672
    Abstract: A high frequency audio amplifier in which the positive and negative bias ports of an operational amplifier are employed to drive two oppositely phased current mirror circuits. Additionally, the outputs of the current mirror circuits are current regulated in terms of the number of base emitter voltage drops in power amplifier circuitry following the current mirrors. Further, the output stage employs parallel connected radio frequency type transistors.
