stk4141 circuit diagram: STK IC is the best IC in the sound World. Nowadays there have many transistor amplifier circuit boards on the market. Stk 4141 is a class AB amplifier. although now we can get many classifications of amplifier circuits in our market. now transistor amplifier is so popular …

how to make an amplifier using transistor TTC5200: Today we can learn how to make an amplifier using transistor TTC5200 only. normally we use TTC5200 and TTA1943. but in this circuit diagram, we can see only TTA5200. we must need center tap voltage. Center tap transformer for transistor amplifier. transforms electrical energy …

how to make a voltage regulator using a transistor: Today we are going to learn how to make a DC regulator. it’s a very simple project. We need only an NPN transistor. here we use TTC 5200 transistor. and we need one 100k variable. we can control 6 voltage to …

how to make an inverter generator: Making an inverter is very easy. What is an inverter? An inverter is a way to convert the voltage. It can be low to high or high to low voltage. normally we make low voltage to high voltage according to our needs. But we …

Transistor circuit using A1941 and C5198:  The transistor circuit diagram using A1941 and C5198 and Transistor circuit diagram using A1943 and C5200 are the same. the only difference between the voltage and the transistor. all resistance is the same. In the transistor circuit diagram using A1943 and C5200 are used …

how to make a power doubler: sometimes we need to make the power doubler. If we need 24 voltage but we have 12 voltage transformer then what to do? we had opened only one way that’s to make the power doubler. it’s so easy to make the power doubler if …

12-volt to 220-volt inverter circuit diagram: Today we are going to learn how to make 12 volts to the 220-volt inverter circuit diagram. it’s a very simple circuit diagram. here we use only 4 transistors and 4 resistors. the transistor is 2N3055 and the resistor is 5 Watts 330ohm or …

how to add more transistors to the amplifier: We are going to add more transistors to our amplifier. here our amplifier has 2 transistors 2SA1943 and 2SC5200. this amplifier can make 105 watts. here one transistor can take 1.2 amperes. so 2 X 1.2 ampers = 2.4 amperes. and we …

How to make battery charger? Here in this post, we can learn how to make Battery charger for any battery. How to make battery charger we are going to make 0-12-24-36 voltage battery charger. we need to charge 3 battery together. normally we can buy many kinds of battery. many kinds …

Reflection or echo of sounds Reflection of the sound is called echo. If the sound is interrupted somewhere in the wave, it returns to the previous place again, it is a reflection of sound. The sound that is reflected, so the echo. That is to say that the recurrence of …
