Low noise tone control circuit using C945

If you have electronics old equipment, keep many long ago year, unknow build Electronic Project good. I begs for to advise pre tone control circuit this. By it can fine to decorate the sound Bass,Treble and Volume well.There is the prominent point that use transistor, But be of good quality of good sound doesn’t be defeated the circuit that uses the integrated circuit. By the thing that me observes clear, be the noise is low, bland sound are good. from your circuit can use transistor number C945 or C828 or C1815 can replace. Which the price is inexpensive the hardware is other may get not difficult. The power supply , should choose that be model dc regulator 12V to 24V building may use PCB a bird purposes all right which , good easy.

Tone Control Mono by 5 Transister (C945)

I am interesting about stereo amplifier high quality. My father tell me it must hear sound well, low noise and so loudly.
Usually audio tone control made with a transistor that low noise , but less power than used IC systems. I think this circuit will be that because it has four transistors in diagram.we can also use to boost up a little audio signal.
In the image circuit is mono form. The transistors has five, number C945 or C1815 or C828 . I hope you can find it at general electronic store or inside an old pcb. You can use the power supply source during voltage 12V to 24V at minimum current at 100mA.
The picture no. 2 is PCB diagram for make this project, it small size so easy to use. You can use StripBoard-3U Uncut Strips 1 Sided PCB because it has a few components.

Tone Control Monoby 4 Transister(C945)

If you want to made a audio tone control in small size project common because it easy and non expensive. We are introduce this circuit it given classic sound for you rest very well. It is use to an old transistor 2SC945 but popular past to now,so we are like it. In show for Mono system if you want a stereo, then to make they with 2 packs or two channel the right and the left only. The power Supply used Volt minim 12V at little curent100mAmp.
Detail more please view in picture circuit and to build small PCB.
