The Velleman K4003 2 x 30W Audio Power Amplifier Kit is a perfect drop-in power amplifier designed around the TDA1521 IC.
This small amplifier is constructed with the TDA2616 IC, with a maximum supply capability of 2 x 15Wrms (4ohm) of 2 x 10Wrms (8ohm). The IC is thermally and short-circuit protected. Additional rectifier and smoothing filter are unnecessary, as alternating current can be directly connected to the unit.
