Audio Amplifier Using an Old Panasonic AN 7130 4.2 Watts IC

This video shows the circuit construction of an audio power amplifier using an old Panasonic AN 7130 4.2 Watts IC. It also displays the datasheet of Panasonic AN 7130 IC, which shows its internal schematic, pin configuration and working parameters. This is one of the IC from a set of ICs that I collected a few years ago.
