by Velleman

This small 7W Mono Audio Amplifier Kit is constructed around the TDA2003 power audio IC and delivers 7 watts of music power into a 4 ohms load.

The RMS power is 3.5 watts into 4 ohms or 2 watts into 8 ohms with a THD of 0.05% at 1W, 1 kHz. The signal/noise ratio is 86dB; the frequency response is 20Hz-20KHz at -3dB. The input sensitivity is 40mV/150Kohm.

The IC is thermal overload and short circuit protected. Requires a 8-18V, 0.5A - separately sold - power supply.

The kit's instructions are easy to follow. All you need is a soldering iron, solder and you can start building.
