Easy simple stereo amplifier circuit using TEA2025B IC - powered by 5 Volt USB

A very simple stereo amplifier circuit using TEA2025B IC chip powered by 5 volt USB. The component is quite are not very complicated just some electrolyte capacitors and ceramic capacitors as well as potentiometer. The sound is extremely loud - I am pretty sure further research to improve the circuit will produce good sound especially the bass.

The schematic is shown as below.
