This circuit consists of a single transistor as amplifier and it gives a nice amplification to weakest and unipolar signals for feeding to a real amplifier.
The center of this circuit is a BC547 OR BC548 transistor and the rest of the circuit is few resistors, and capacitors.
The diagram and also the PCB layout is below.
Hi sir, i am made this circuit but sound is not requard, i am powerd this circuit 12v 1A transformar plz give me a sugation…..
If sound is not required, why you made this circuit?
i made this circuit to amplify condenser microphon sound
It’s still unclear. If you don’t need sound, why you’re playing with microphone and this circuit.
first i amplify the microphon sound via this circuit and then i added the sound my 4440 ic amplifire
Yes.
