Velleman K4003 - 2 x 30W Audio Power Amplifier Electronic Kit (TDA2616)
This 2 x 30W (PMPO) hi-fi quality stereo audio power amplifier SELF-ASSEMBLY electronic kit may be small in size but the TDA2616 IC based circuit outputs up to 2 x 15W rms @ 4 ohm or 2 x 10W rms @ 8 ohm.
The IC is protected against overheating and short circuits. Additional rectifier and smoothing filter are unnecessary because alternating current can be connected directly with the unit.
