Only 7 In-Stock Remaining.
This small amplifier is constructed around the TDA2003 Integrated Circuit (IC) capable of delivering 4 W rms at 4 ohms. The
IC is completely thermally and shortcircuit protected. A conventional
analog direct current (DC) power supply can be connected. Manual shows
ans example power supply.
