Tone controller

This low distortion tone control circuit is used LM1036 IC to control the Bass, Treble, Balance and volume of any power amplifier. You can use this with Hi-Fi audio, car audio, TV audio systems. The specialty of this tone control circuit is you can supply 9V to 16V DC current. But never go to try more than 16 Volts.  Also it has a large range ( 75 dB ) of volume.

Output capacitors should be 10uf 25 Volts. If you want to add this to a stereo amplifier then you need to make one more tone control. To get best results use screen wires for controllers and inputs. Also try to use half watt resistors and when fixing capacitors make sure to consider the polarities.
