Electronics Help Care electronics circuit diagram

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 …

Inverter for amplifier: This is Inverter for amplifier. 12 voltage to 35-0-35 voltage inverter circuit diagram. this circuit makes 12 voltage to 35-0-35 voltage. transistor amplifier needs dual voltage. positive voltage, negative voltage and ground voltage. we can’t use 12 voltage battery to this transistor circuit. if we want to …

Fixed voltage regulator: How to make a fixed voltage regulator? it’s an easy circuit diagram to make this circuit. we can use 100 voltage input and the output will be according to the ziner diode. here this circuit used 15 voltage ziner diode. so we can get 15 volts from …

How to make a diode: It is easy to make a diode using a normal rectifier. Here we can see how to make a bridge rectifier using a normal rectifier. One diode has 2 sides. Anode(+). Cathode(-). In theory and practice this symbol is different. In practical Cathod will be …
