pre amplifier for the amplifier:
This is the pre-amplifier for the amplifier. this is the circuit to increase the sound. we use this circuit for the amplifier to get better sound. normally it is used with a bass tone circuit. here used 12 voltage. this is a mono-circuit diagram. for the stereo, we have to use 2 circuits to make stereo.
5 band equalizer circuit:
This is a 5-band equalizer circuit diagram for an amplifier. every amplifier needs a good-quality bass-tone controller. we usually use volume bass and tone circuits. or bass midrange and tone. but here we use bass, semi-bass, mid, semi-treble, and treble. 5 graphic. this is without a pre-amplifier circuit board. here needs a pre-amplifier circuit. In my next post, I will make a pre-amplifier for this circuit.
