This document provides a circuit diagram and specifications for a DBK 3000 audio amplifier. The circuit uses transistors, diodes, resistors, and capacitors to create two identical audio channels labeled A and B. Each channel can deliver 10 watts of power to 8 ohms of load. Safety features include overcurrent protection up to 10 amps and 250 volts. The power supply provides regulated +/- 15 volt and +/- 6 volt rails from a 44.1 volt transformer.
