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.
thanks
This thing WORKED... Prior I thought it is trash but when I made it it worked 100 percent... THANKS DUDE
congratulation, 😘
Bahut badiya bhai,
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
what speaker resistances can you use this amplifier at? and what is the max voltage you can put into this cct?
Super. Ovoru sparelayum price pota Innum nallairukum. I THANK YOU
The explanation about the conductors and capcititors and how to connect is to be explained while doing is more effective and useful

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.
but the heavy sound is what makes it fun
3watt & 8 ohm speaker ka amplifier kaise banayen ge ye batwo bhai ishpe bhi ek video bnawo
The fly seems to like your music, then, it has to be a good project !!
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
Legal porque ele da detalhes de cada componente , valeu!
The world would be so wonderful place, if this amplifier had 100W... :-)
Angry Student , ага! 100W он из 12 Вольт решил добыть, да еще на двух транзисторах!Сказочник))))
Такое возможно только в России!))))
Loved your comnt angry student
Speaker is 8 oum or what
Eu tenho uma fonte de 18 volts, tem algum problema usá-lo neste amplificador?
muy bueno el circuito del amplificador pero no se vio como se alimenta de voltaje
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!
👍✅ Your analysis is very good
Where does your starting 20 W number come from?
@@EricFontaineJazz assuming his understanding and assessment of the parts is correct, he gets 20w after subtracting the theoretical thermal energy wasted from traveling thru the circuit.
Gostei do amplificador é muito bom ok professor, Fais um amplificador com 2 transistos tipo 127 ok
Kya in dono ic ki jgah B 817 d1047 ka use kr skte h kya?
Koi ans do
Muy bueno, simple y efectivo
Is that plumbing solder paste you are applying to the joints before soldering? It's not an amplifier, it's a noise maker ......
Muy buen video.Lo intentar'e.Bendiciones.Muchas gracias.Horacio.Cali.Colombia.
thanks a lot
It would be more interesting if you could provide a full explanation of this scheme.
Está bueno al escucharlo ringtones,cuando lo separeste de la mesa la bocina se a claro.angel de nicaragua
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
thanks a lot,,,
is transistor se 100+100 stereo 24 0 24 volt pe amplifier bna sakte he ke nahi plij dayagram
felisidades quedo muy bueno ya lo hice y esta muy bueno
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?
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 work brother
Thanks ✌️
can you add something to make it smother? more caps? as i have no clue in this but intrested building something like this
i will add more component.
make it.it is a good amp
MUY BIEN
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.
Nice n easy amp ... Can work truly...? Very good... I try later if work then ..I make stereo amp ... Thanks 👍😀😀😀
12v ok 1 amp or 2 am
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
Olá meu caro, tem como fazer um amplificador de 5000 w
of course I will try to do it I will hope that it will work
sure
Volume control fit karskthe hai kiya
Can you tell me the song or the last track on your video because I really like it? Thanks
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.
Nah! first things 1) cutting finger nails
2) wash hands
But that's not the way this particular circuit works
I test the circuit on LTspice, and it works. But it is a class C amp, only half wave above 0V got amplify, and signal below 0V is all flat, kind shiity in audio application
.
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)
垃圾视频！
Muito bom! Fantastico!
thanks a lot
Qual o valor minimo de corrente fornecido pela fonte? 2Amperes?
On your audio input where is the right or left channel hook up or are you not using the ground off the phone
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.
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.
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.
500K resistor VS 50V DC 😮 power supply to speaker booster 500W 2x 13003 transistor amplifier 😅 power high 😂😂❤
Молодец продолжай так же! Лайк
Very good and useful video, I'm a loyal fan waiting for the next video, always successful
Glad to hear that,,,,
thanks a lot
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.
Si
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.
Its already burned i can fell the distortion
Then what 12v dc amplifier would you recommend I really need it
Brother ik video apne orr bnaya hua tha jismai same speaker tha vo nahi mil rahi h plzz bai msg ka reply jarur krna
Bhai power on krne pr speaker phool q ja rha hy
Mery sath bhi ye hinproblem ati hy jb ghr pr bnat hun to
Thank you. I just have 2 questions. What Ohm speaker can it take and what Amp max 12v power supply can be used?
please use a fuse if you are using high Ah battery
THD100% ;D
Wasn't meant for audio, it's an object shaker, as demonstrated.
Dc Curant Cabel Kahan Lagani Hai ap ne crant cabel nh lgai...?
I will try it now.
SERIA BUENO CREAR UN DIAGRAMA PARA SER MAS CLARO
why are you putting things on the speaker then the speaker will distort ,we are here for the sound quality!
Because he wants to hide the extremely high distortion.
And how do you turn on those pieces or do you put a battery?
Bom dia,me tire uma duvida
O senhor tá usando pilha ou na energia?
Kkk deve tá ligado na bateria do celular 🤣🤣🤣
Se ve y oye que sumba excelente
great amplifier circuit
Super bro
Сел бы на динамик может тоже подбросило вверх) а вообще красава! 👍
oh my God where the power supply?
your'e just dreaming...
The only thing missing is the Flux Capacitor to really get those Bass vibes.
Flux capacitors are only suitable for high frequencies--no good for bass.
Klingt abscheulich. Wäre mal interessant wie der Verstärker verzerrt (Oszilloskop)
200 prozent
That bass sounds AWESOME! I'm gonna put this in my car and cruise the neighborhood!
"How to to make a very poor highly distorted amplifier"
Nah it sounds like the speaker is badly blown and damaged
Why does the speaker have 2 red wires but the amp has a black and red wire
@@bryang9601 thats the real amp, sounds like trash just like the plans would. The red speaker wire is going along with the black dc- wire to the ground at power supply most likely
Don't criticize him for his wire colors--criticize him for showing a project that's completely useless at best, and very likely a waste of time, a speaker and perfectly good components.
Because red wires can handle more power and black wires are only for small signals ( don't you know the "Colors Law for Applied Electronics" It is the most important law in modern physics . hahahahahahahaha
sar is 4 transistors se 200 wot amplifier kese bnaye 18 0 18 transformer isme chal sakta he kya
1minutes nice working Heavy Heat Sound problem
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.
With that simple configuration I would agree 100watts is not realistic however if the 12volt source has allot of current like a car battery it is obtainable.
That’s true, he could be using a computer or Xbox power supply for more current to power 100 watt at 4 ohm.
@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.
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.
Guess that explains why I here is different amps with varying quality got four or five different "pros" telling us how to get it done right
Lol
Guessing this is the low end scale of the quality
Действительно 12Вт. Из википедии. Но простота усилка удивляет...
Кидалово удивляет
ayos galing mo boss
Pwedi ba 2.100 watts isapkl sa DIY nayan
Все красиво, кроме звучания!
звучание и должно фонить
а как он должен звучать если это низкочастотник и вдобавок без короба
Затея не плохая, но мне кажется проще купить уж на полкиловата
Динамик открыт, отсюда такое звук. А подключить колонку, будет супер-звук.
@@user-gx7mc8sg6p не уверен, питание слабое,нужно минемум для 100 вт хотяб 32вольта
Não VII onde vc alimento com os 12 voltes fuciona sem corrente
Nice
good idea
He takana binabattery re challibakie

Someone can help me..l want à digrammes circuit inverter simple easy to make it fonctioned.four résistance 2 z44. And capacitor
Yeah I know
What people will do for a Viral Video. But hey, nice attempt on the amp 🌴💀👍
Good job 👍
There should have been one capacitor connected between the speaker and audio output. If i am not wrong then dc voltage gets to the speaker which is defintely not good. Also a good amplifier has to have split power supply.
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. . . . . .
THANK YOU SO MUCH
Glad it helped
The one I made the way you made it works well
we need one that does not output DC for Speaker Because Speakers hate DC and it ruins the Voice Coil in Them
Yup
Yeah, putting any form of dc power can fuck up you're speajee. But if he want untangled and burnt coils nkt my problem hehe
It is 50w-50w amplifier
Super super super super super fantastic
Thank you so much
So many hate comments but those those haters can't even make thier own and post it on youtube so that we have a comparison about thier work that suits on thier expert level opinions.
If it's wrong then please make your version and post it here.
thanks, bro,,,😘
One needn't make something to recognize how flawed this one is. It is a waste of everyone's time who watches this, and highly irresponsible to claim, however incredibly, that it is in any way an audio amp.
Только я что-ли заметил, что винты поставил без изоляции, тем самым соединил оба коллектора
Пересмотрев видео, обратите внимание что на сами винты уже одета изоляция
Нет, винты на изоляторах, смотри внимательно. То что 2 винта на коллекторе, ничего не значит, они не прикасаются к транзисторам!
Видно глаза нарисованы на голове))
Кепку сними блядь.
The Internet: The home of poor designs.
Wowww great job
Muy bueno para aprender
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.
kkkkkkkkkk
Fuck man go in your ass someself.
Oh look the screw driver to oh look the speaker lead and if you missed it oh look the same speaker lead following up putting junk on the already distorted speaker.
@SPEAKER GUY hii
Si el capacitar es de 470uf/35 volts da lo mismo o tiene que ser 25 volts
sure
nice project
Thanks
