In this video, we are going to show you making a Powerful amplifier circuit using only two transistor. It is a super loud amplifier circuit. You also try to make this amplifier at home easily. Using Only DC 12v you can operate this amplifier circuit easily. you also can use inside your car, bike, truck, etc.
To make this circuit, you might need some electronics component. Those component list have to been given below.
Component List :
1. Transistor - Tip 122
Tip 127
2. Volume - B 100 K
3. Capacitor - 470uf / 25v
4. Resistor - 150 k ohm
5. Speaker - 100 watt
6. Power Source - DC 12v
7. Heat Sink
8. Connection Wire

Must of you guys here just criticize negatively. I would like to see if some of those dudes who are negative construct and explain something better. This guy is doing something for those who are beginners such as high school students where people that don't have any knowledge of circuit theory and how to polarize a transistor. Those carpers should share and at least to advise and how to improve this. it also misses and preamplifier and active filters to avoid saturation on low frequencies. The concept is perfect and simple. It is a power out stage.

Typically, when one demonstrates how well an amplifier circuit works one builds, they demonstrate how good it sounds. This circuit simply demonstrated that it could drive a speaker's voice coil windings enough to make the cone of the speaker vibrate & bounce assorted objects around. I believe some sound was emitted from the speaker however, it was distorted beyond the point of recognizing if it was music or perhaps grunting noises made by certain animals in the wild.

@ToddHofer 4 жыл бұрын

You are seriously connecting a +12v input directly into a speaker? Notice as soon as you applied power, the cone popped straight out? That should have been your 1st hint that it is a bad circuit. Any 1st year electronics student can tell you that speakers are AC output devices. You don't plug DC directly into them. That's what burns out voice coils. Audio amplifiers take an AC Signal input and, converts it to a stronger AC output signal. DC is used to power the amplifier. Not amplify an audio signal. Audio is an AC, Amplitude modulated signal. Distortion is caused by an over modulated audio signal injecting square wave DC into the audio. That's what fries voice coils. If anything, you have created a voltage amplifier. NOT an audio amplifier. Also, 100 watts. Not with that circuit. My advice to you is go back to a 1st year electronic course book and learn how to design a proper circuit before some beginner uses your video and then blows an expensive set of speakers or, worse yet, causes a fire. What you have shown here is a potential for, at best, lost money. At worse? you could kill somebody in a fire. Shame on you.

@vincentrobinette1507 4 жыл бұрын

The speaker sees 6 volts with zero signal. This is a class "A" amplifier, the 2 transistors are connected in a "Darlington" circuit, with the TIP 122 serving as the input stage, The TIP 127 is the output stage. The problem is, the speaker coil dissipates 9 watts, if it's a 4Ω speaker, 4.5 watts, if it's 8Ω.(no signal)

This would be a 20W sound amplifier if there were no heat losses in the transistors. Considering this is a Sziklai (compound) pair of two Darlington IC's, I think it falls under the AB class amplifier. AB have around 75% efficiency, so one quarter of the total absorbed power would be pure heat. One quarter of 20 is 5, so 5W (or more) are dissipated into that heatsink as heat. A 15W amplifier with two Darlington transistors is still okay, mind you. Great job!

12V applied across a speaker CAN NOT dissipate 100W of energy. 12V across a 4ohm speaker will dissipate 36W, 12V across a 8ohm speaker will dissipate 18W.

@EricFontaineJazz 2 жыл бұрын

The video title is very misleading because speaker impedance tends to not be less than 4 ohm. But the equation Power = (Voltage ^ 2) / Impedance does have a solution for 100 W peak power across 12 V if the impedance is 1.44 ohms. I just did a web search and see there are car speakers that are 2 ohm (which according to the equation could dissipate 72 W peak power with 12 V) and even 1 ohm (which according to the equation could dissipate 144 W peak power with 12 V). Of course that is peak power (not RMS) and isn't accounting for other issues, such as the limitation (according to the datasheet for the TIP 122 and TIP 127) that the absolute max rating for these transistor's collector current is 5 A and a peak of 8 A.

@EricFontaineJazz 2 жыл бұрын

and there are other power losses such as in the transistors, and some one in the comments below is saying that since this is a class AB amp, it can only have 75% efficiency too.

What a brilliant design. Using darlington pair with current gain of 1000. Feeding the circuit with a 0.1Watt music source, x1000 times, you get a ball-park of 120 watts. What you get is, with 12 volt supply, the high gain of a small sine wave got magnified and clamped at 12 volt and became a square wave, makes it sound shitty. The output of the circuit has a AC and a DC component. You are effectively making a degauss circuit for demagnetizing your speaker.

@matthewstorm5188 4 жыл бұрын

@Robio Weeks 100W is perfectly attainable from a 12V source (like a car battery). But not to a 4 ohm load. At a maximum (which would be pure DC), you could get 36W from 12V into a 4 ohm load. The minute you start to generate waveforms (which will lower the RMS voltage from pure DC), this figure decreases further. Put in another way, in order to get 100W into 4 ohms with a pure DC voltage, you need 20V. Make that a sine wave, and you now need a voltage source with an amplitude of 28.2V. Oh, and that’s into a pure resistive load.

@stevekolhoff9240 4 жыл бұрын

No, it is not. UNLESS. you put the +12VDC through a DC-DC switching power supply which boosts the +12VDC to at least +/-40-45VDC. Only then can you get 100W into 8Ω. 200W into 4Ω. Not trying to kill the creativity here, just want to point out the reality.

The sound is not good... because it’s not a subwoofer amplifier and he connected a subwoofer. I tested with a HI-FI speaker and it sounds good! I have an idea with this amplifier... replace the speaker by a 33ohm 50W resistor, and at resistor pins you have the output. Connect speaker in series with a 6800uf capacitor and it works better! Then it won’t destroy the speaker! The resistor will heat, but if it is a 50W resistor you don’t need heat sink! Power this with 6 to 36V! You can also power it with 48V but you have to replace the 150K resistor by a 220K resistor!
