Hybrid Stereo Amplifier 2 x 25 Watt (RMS)

This complete high quality, low noise stereo audio power amplifier is based around the Hybrid Integrated Circuit STK4392 manufactured by Sanyo. The circuit incorporates volume and balance controls and has a maximum music output power of 35W per channel (25W per channel RMS). The circuit incorporates an on board power supply; therefore, only an appropriate transformer is required to power the circuit.
