Schematic - Simple Mini stereo amplifier circuit diagram
This circuit shown a simple build up schematic for basic mini stereo amplifier circuit which is based on MC1458 dual op amp and LM378 dual audio 4-watt amplifier.

The Gain of the preamp is given by R3/R1 for one side and R4/R2 for the other side, which is about 100 and can be varied by increasing it’s ratio.

The two of 8 watt loudspeaker driven by these 2 amplifier.
