3 Transistors Pre Tone Control Circuit

Here is a classic Tone control circuit. It uses a low noise transistor model. Which this circuit is interesting. Because of transistor entirely then have a voice good and economize good.

See in the circuit below.  this use transistor 3 pcs. For pretend pre-tone model mono, if you want to use are the system stereo. As result building, this circuit enhances again the group only.

The prominent point of this circuit again type, be use power supply source good wide be about 9V – 18V and should be DC regulator with. The detail is other friends see in the circuit adds yes.

Classic Tone Control using 2 Transistors 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.

Designing power amplifier Circuit is high quality. The some is the thing that must think over most. Be Pre tone control circuit, but friends must not worry. I have this circuit that it transistor all work in feeding character gets back to model specialty. Be use Constant Current source be something bias that get from LED help have the stability in manner temperature work of Q1 and Q2 improve. The input can take a signal has since 100mV-1V don’t fear about Over Load, and the crazy low very. For other equipment can choose use general equipment. By sound quality still use well yes.

OLD Tone control circuit using 4 low noise transistors

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.

Classic Tone control circuit using 3 Low noise transistors

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.

High quality Tone Control Mono using 5 Transistors 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.

  1. It worked great but the treble could not be heard clearly.

  2. dear students plz c this circuits and dnt mis use this circuit

  3. hi l am benjamin form ghana i lake to do eletronic bat i need a help whit componet. ido not have maney to bye so pelese help me

  4. mine is not working…. all the components are complete but there is no sound…. let me check admin transistors are c945 which is npn in the a561 pnp?? i dont know where i wrong.. this is my 3rd time building ma own circuit… this is only not working.. can i ask u mensah can u sent me ur photo on this circuit.. please… ty

  5. really want a 5 transistor amp –using Only available BC 547/557 TRANSISTORS—

    CAN U CREATE SUCH A CIRCUIT ?
    NONE OF YOUR RARE ODD TRANSISTORS CAN BE FOUND!

    IS IT POSSIBLE?—-WHAT WATTAGE OUTPUT WILL I GET?

  6. BC 547——BUILD A CIRCUIT 4 ME—-5 TRANSISTORS
    THANKS —-CARL WINTER

  7. I like how concise your notes are. It is one of greatest dreams to build an audio amplifier myself but unfortunately , I the basic knowledge about ;

  8. Its work fine , I used 4 x 2N3904 and
    1 x 2N3906 for TR-3
    Thanks

  9. y mine s not workng…fdbak some trobleshotng plz…i used cap 10uf/16v @ ur layout 10uf/10v…s dat ok??..

  10. Do you have any video of that? I’d want to find out some additionaal information.

  11. It always seems to work much better if you use a separate Input amplifier, conected to a Tone control [baxandall] circuit, which is in turn connected to a output stage which feeds the main amplifier. You do not need high power amplifiers for home use, Ten Watts [x2] of stereo sound is plenty and also cheaper to run. The more power you use the easier it is to generate more distortion. A distortion figure of up to .1% is very acceptable. I have used this system for many years with trouble free operation. My frequency response is 10HZ to 50KHZ. Your speakers play an important part in the final sound reproduction and must be capable of reproducing 10HZ to 50KHZ. The better your speakers are the better quality of sound you will hear. HL.

  12. thanks ..

  13. hey, great, can i use this 7 number pcb in my 200 watt rms power subwoofer??

  14. So awesome frequency response and fidelity. I adopt this setup to hi fi PA sound enhancement tecnique with stereo studio master PA amp. Thanks.
