The amplifier circuit High Tone (Treble)

Components:

Resistor                                : R1 150k

                                            : R2 470k

                                            : R3 2k2

                                            : R4 10k

Potensiometer                      : RV 10k tipe A

Capacitor                             : C1 0.05µF

                                            : C2 0.47µF 

                                            : C3 3n3F

Transistor                             : Tr1 BC 108

If your sound system or amplifier treble tone was already weak, you can create a circuit like the picture on the side. In this case the OUT channel can be connected directly with loundspeaker.
