18W TDA2030A Hi-Fi Stereo Audio Amplifier Kit

Stereo power amplifier based around two TDA2030 ICs. It has good input sensitivity, low distortion, good operating stability and full protection against overloads and output short-circuits.

18W TDA2030A Stereo Audio Amplifier Kit can be used as a booster amplifier for existing small systems or to drive a second pair of speakers besides the ones already connected to the system.

The board needs a dual power supply of �18V and can be connected to 8 or 4 Ohm speakers. Heatsink not supplied with the kit.
