Low Voltage Mini Stereo Amplifier

The circuit is easy to build, it can be done easily on the edge strip, although I never tried to be honest. As always make sure that you insert TDA2822M chip on the board the right way and you get electrolytic capacitors in the right direction, I recently blew one of the greatest speakers I mentioned above. Nothing else is particularly critical, as the amplifier to operate with the lowest resistance and capacitors, you can buy. A log-log pot is recommended because it allows easy adjustment of volume. Everything else can be added as you need to know the tone controls, etc., but it is unlikely that you'll need something else for simple systems.
Voltage range betwen 1.8 V - 18 V
