How To Make Powerful (100 Watt) Amplifier Circuit || DC 12v 

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.

Muy bueno, simple y efectivo

Legal porque ele da detalhes de cada componente , valeu!

Super. Ovoru sparelayum price pota Innum nallairukum. I THANK YOU

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.

Bahut badiya bhai,

Muy buen video.Lo intentar'e.Bendiciones.Muchas gracias.Horacio.Cali.Colombia.

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.

The world would be so wonderful place, if this amplifier had 100W... :-)

felisidades quedo muy bueno ya lo hice y esta muy bueno

MUY BIEN

This thing WORKED... Prior I thought it is trash but when I made it it worked 100 percent... THANKS DUDE

Saman uchkane ki mashin👌👌👌👌👌

Gostei do amplificador é muito bom ok professor, Fais um amplificador com 2 transistos tipo 127 ok

ayos galing mo boss

what speaker resistances can you use this amplifier at? and what is the max voltage you can put into this cct?

Is that plumbing solder paste you are applying to the joints before soldering? It's not an amplifier, it's a noise maker ......

Сел бы на динамик может тоже подбросило вверх) а вообще красава! 👍

Молодец продолжай так же! Лайк

muy bueno el circuito del amplificador pero no se vio como se alimenta de voltaje

Eu tenho uma fonte de 18 volts, tem algum problema usá-lo neste amplificador?

the best video so far easy to get parts and build unlike some other videos using parts that isn't available at jaycar electronics and altronics in western Australia, Australia except the tip27 dam it and after reading the comments this circuit has errors maybe its using the wrong speaker maybe it needs an 8 ohms one

Wowww great job

Hello friend, greetings from the United Mexican States, I wanted to ask you if you connected it to any source of power, I wanted to know or tell me clearly, that in your video it does not look like you connect it, I did not understand well, your video is good

3:57 - OMG jaki prąd spoczynkowy, połowa napięcia zasilania :D ja bałbym się podłączyć to coś do smartfona. 3W to wszystko co można na tym wyciągnąć z kondensatorem wyjściowym 4700uF.

The explanation about the conductors and capcititors and how to connect is to be explained while doing is more effective and useful

Nice

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!

Muito bom! Fantastico!

good idea

Not a recommended amplifier design when the cone of your speaker pips out when power is applied. That means it's getting DC voltage and potentially burning the voice coil.

Olá meu caro, tem como fazer um amplificador de 5000 w

Muy bueno para aprender

Muy interesante

oh my God where the power supply? your'e just dreaming...

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.

Good job 👍

Mantab.

As an experiment is fine, I would have to put filters to see how much it really performs, possible 8w, for that I would better use a TDA2003 that if it would give a better sound

great amplifier circuit

nice idea dear friend

great work brother

THD100% ;D

Se ve y oye que sumba excelente

Very good and useful video, I'm a loyal fan waiting for the next video, always successful

Nice n easy amp ... Can work truly...? Very good... I try later if work then ..I make stereo amp ... Thanks 👍😀😀😀

With a voltage of 12v it is impossible to get 100e over 4 ohm. Don't you know Ohm's law? Well, before giving electronic lessons, you should know it since it is the basic law of electricity.

why are you putting things on the speaker then the speaker will distort ,we are here for the sound quality!

Muy bueno

Pretty good stuff

I like that you wrote exactly what you were doing it was very helpful most of these videos they do it so fast and looks like they skip steps thanks

of course I will try to do it I will hope that it will work

👍👍👍 mantaaaaf...😍😍😍😍

The fly seems to like your music, then, it has to be a good project !!

Your explanation is excellent, simplified, and very nice. Keep it up, Bechmhands engineer. We support you. Can I have a simple request? I have a 4 ohm headphone, 100 to 600 wat, 5 volt.What amplifiers and resistance value do I need?

This is stupid. Not only that principal scheme never work but even if it would the rms power formula for amp is (U/2 )^2 / 2Rs = (12/2)^2 / 4*2 = 4.5w (assuming that speaker resistance = 4Ohms) This value is maximum possible.

Good job

Super bro

SERIA BUENO CREAR UN DIAGRAMA PARA SER MAS CLARO

"How to to make a very poor highly distorted amplifier"

A distorção tá foda

EXCELENTE VIDEO, me funcionó muy bien con un TIP31C y un TIP32c

500K resistor VS 50V DC 😮 power supply to speaker booster 500W 2x 13003 transistor amplifier 😅 power high 😂😂❤

Very low quality distorted sounds

Thanks for share

That bass sounds AWESOME! I'm gonna put this in my car and cruise the neighborhood!

Все красиво, кроме звучания!

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.

I will try it now.

Superb

Why does the speaker have 2 red wires but the amp has a black and red wire

He takana binabattery re challibakie

What people will do for a Viral Video. But hey, nice attempt on the amp 🌴💀👍

It is so. Power ful

The Internet: The home of poor designs.

Thank you. I just have 2 questions. What Ohm speaker can it take and what Amp max 12v power supply can be used?

Nice performance

Gazab

The only thing missing is the Flux Capacitor to really get those Bass vibes.

Действительно 12Вт. Из википедии. Но простота усилка удивляет...

I like this bass

Me gustan esos proyectos

Não VII onde vc alimento com os 12 voltes fuciona sem corrente

Только я что-ли заметил, что винты поставил без изоляции, тем самым соединил оба коллектора

Boht powerful board bnaya tha orr bhi components the usme Apne 3 ic ka use kia tha orr capistor bhi brda use kia tha 1000 + uf tha usmai

Nice video bro

Someone can help me..l want à digrammes circuit inverter simple easy to make it fonctioned.four résistance 2 z44. And capacitor

Отличная взбивалка яиц

On your audio input where is the right or left channel hook up or are you not using the ground off the phone

THANK YOU SO MUCH

we need one that does not output DC for Speaker Because Speakers hate DC and it ruins the Voice Coil in Them

We can all bitch about everything wrong in this video but the fact is that this guy is showing us just the principle of a little circuit. Eventhough his standards for "Awesome sound quality" is a bit off.

Qual o valor minimo de corrente fornecido pela fonte? 2Amperes?

Lol the ending 😂😂

Primero que no se deben colocar objetos y mucho menos tan pesados sobre el cono del altavoz y segundo que sera muy simple el circuito pero así suena malísimo. . . . . .

"Awesome sound quality" *literally shitting-self*

nice project

Very nice amflair

It is 50w-50w amplifier
