The 400W Power Amplifier “Safari” circuit diagram
The 400W power amplifier designed using two couples of power transistors that are TIP31 with TIP32 and 2N3055 with MJ2955. These types transistor are well known and widely used for the amplifier circuit and high current low voltage DC power supply circuit.
In the electrical sector, a schematic diagram is usually used to describe the design or model of equipment. Schematic diagrams are usually utilized for the maintenance and repair of electronic and electromechanical devices / units. Original schematics were made by hand, using standardized templates or pre-printed adhesive symbols, but nowadays Electrical CAD computer software is often used.
In electronic design automation, until the 1980s schematics were virtually the only formal representation for circuits. More lately, using the progress of computer system technology, other representations were introduced and specialized computer languages were developed, because with the explosive development of the complexity of electronic circuits, classic schematics are getting less practical. As an example, hardware description languages are indispensable for contemporary digital circuit design.
