Mono audio tone control with three transistors C945

This tone control circuit diagram of the home audio stereo is very well. It low noise and sound is beautiful because use the quality transistor.
In picture we used three transistor number are C945 or C828 or C1815 or C458 They are old electronic components but useful now. They are mono form if you want stereo system, to make two section R+L. The VR1 is 100kB for finning treble tone sound. The VR2 is 100K for finning bass tone audio as well. The VR3 is 100Ka for control volume output. The VR4 is 100KW for control balane sound fo other channel. The power Supply Voltage used min 12V and min than 80mA .

We hope this circuit will be do you are enjoy a home audio. good luck.

Tone Control Mono by 2 Transister (C945)

This be tone control circuit ,The small-sized. It the character Mono by use transistor just 2 PCS important equipment performs to enlarge sound signal gives the power goes up ,and have a button fines to decorate the sound completely. It be fine decorate the popularity in the sound , fine decorate the treble , and fine decorate the bass as well. It is convenient for a novice wants to try build Pre Tone control circuit keep be usable. The prominent point of this circuit be seek the equipment easily , Electronic part replace can be finished or can antiques sheep comes to use all right ,such as The transistor number C828 may use the number C945 or C1815 or The other all right. For the level power supply also get wide be about 12V to 24V at 50mA you can see other detail in the circuit.

Pre Tone Control Circuit (Transistor)

Notes:
Based on the classic Baxendall tone control circuit, this provides a maximum cut and boost of around 10dB at 10K and 50Hz. As the controls are passive, the last transistor provides a slight boost. The output is designed to feed an amplifier with input impedance of 10k to 250k. Both tone controls should be linear potentiometers.Source : http://www.mitedu.freeserve.co.uk/Circuits/Audio/t-ctrl.htm
