This circuit is a circuit diagram of the balance indicator simple stereo circuit that you have. The circuit will provide a visual indication (using two LED) is proportional to the difference in the balance between left and right channels of a stereo system. This circuit is based on uA741 IC opamp. The IC compares the signals from two channels and when the two balanced signal, the output of the IC will be stable and the LED will shine in the same light. The sound causes an imbalance in the two LEDs to vary in brightness in proportion. Circuit diagram requires 9V power. The following is a schematic drawing:
