1100KT - 18 Watt Integrated Stereo Amplifier Kit (TDA1524A)

Ability Level 3: IntermediateProduct Format : Self-Assembly Electronic Kit ( Soldering Required)
Ability Level 3 : Intermediate

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 board has a power supply section so only a 2x14Vac/4A transformer is required (or 2 x 12Vac/4A with some loss of output power).

Kit includes all board mounted components (heatsinks, potentiometers, rotary switch with mounting board) and solder for assembly.
