Circuit Project Electronic

Friends someone at take an interest build the project power amplifier the small-sized. but get into trouble about seek buy the equipment or do PCB distress. Today I begs for to advise 30W Stereo Amplifier Kit by TDA1521 is electronic kit the small-sized cheapness and order easy change amzon.com although it is not this circuit at is excellent. but I thinks when use the integrated circuit TDA1521 , as a result , may don’t make you are defeated certainly.

Power size 2 x 15W RMS (4 ohm) The IC is thermally and short circuit protected. Specifications: THD: .07% (1W/1 kHz) Frequency response: 7-60,000 Hz (-3dB). Requires 2×12 VAC, 2A transformer (sold separately).
