Classic Tone control circuit with low noise transistor

Today I meets Classic Tone control circuit. That is use low noise transistor model. which this circuit the interesting , because transistor entirely then have a voice good and economize good. From circuit this use transistor 3 pcs. For pretend pre tone model mono , if you want to use are the system stereo. As a result build 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.

Filter the Scratch and Rumble Noise

If a friend gets into trouble about the noise. Try out this circuit before, may like. It is Filter the Scratch and Rumble Noise Circuit. That make a friend feels annoyed very the character of the circuit filters this frequency , use , Resistor , and , Capacitors , or , RC Filter that often call that Passive Filter Circuit. By have Switch choose filter the noise. By SW1 for Rumble noise Filter and the SW2 for Scratch noise filter. Make the noise that change this circuit goes to are left a little for power supply Source should use battery 9V. Because will decrease the noise from power supply , give with this circuit there yes.

Pre Tone Control high quality with transistor low noise

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 has 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.
