Easy preamplifier circuit diagram: This is the easy preamplifier circuit diagram. We use this circuit to the amplifier to increase the sound. here used one transistor. NPN transistor. 2sc1815. it’s the mono circuit. if we need stereo then we have to use dual circuit. we can use 6 voltage to …

How to make voltage 50-0-50: How to make voltage 50-0-50.  here we are making high volt using low volt transformer. We used two transformers to produce this volt. our transformer is 25-0-25 volt but we need 50-0-50 volt. for this, we use two transformers. we don’t use the full wave …

Amplifier circuit using tda2050: This is 30 watts audio amplifier circuit using tda2050. here used TDA2030 IC. This IC can make 30 watts. this is a dual-power diagram. here needs dual power. positive negative and ground voltage. we are using 150-0-15 voltage. we can use 9-0-9 voltage to 22-0-22 voltage …

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 amp to get better sound. normally it is used with a bass tone circuit. here used 12 voltage. this is a mono-circuit diagram. for …

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 …

high current diode making: we can make a high-current diode like this circuit diagram. if we use one rectifier the the rectifier will be very hot. for this case, we use 4 pieces of rectifier to make AC voltage to DC voltage. this circuit diagram helps fully to make a …

Bass mid-tone circuit diagram: This is the equalizer circuit diagram for the amplifier. every amplifier needs an audio controller circuit. this circuit is an audio graphic for an audio amplifier. here are 3 vol for Bass, midrange, and tone. bass for the low part mid for the vocal and tone …

2sc5200 and 2sa1943 amplifier circuit diagram: This is a 2sc5200 and 2sa1943 amplifier circuit diagram. this diagram can make 200 watts. because this circuit used one pair of transistors. One pair of transistors can make 200 watts. we can use a maximum of 40-0-40 voltage and 5 amperes. we need …

audio equalizer circuit diagram: This is an audio equalizer circuit diagram for the amplifier. it’s without a pre-amplifier. if we want to we can add an extra pre-amplifier. Here are many pre-amplifier circuit diagrams. this circuit is for Bass and tone.  pre-amplifier Circuit Diagram Audio amplifier circuit: This is an …

How to make resistors as we want: This is the resistor-making law. how to make a resistor. I am always taking the easy way for all my friends. before we have to know that 1000 ohms is 1k. 2k=2000 ohms. 3k=3000 ohms. if we use 2 pieces of 1k then …
