1100 - 18 Watt Integrated Stereo Amplifier

A complete STEREO amplifier in one board based around the popular TDA1524A IC. It has 4 inputs (P.U., AUX, TUNER and TAPE). It is designed with the latest technology and uses DC for the BASS, TREBLE, BALANCE and VOLUME CONTROLS.

Ideal for use as a booster for WALKMAN. Frequency response 20Hz-20KHz with only 0.5% distortion.

The power supply is included in the amplifier board and only a 2x14VAC/4A transformer is required. Kit includes all board mounted components (heatsinks, potentiometers, rotary switch with mounting board) and solder for assembly.
