Mujhe ye banana hai to sman kaha se milega
Ya ye kit chahiye jo aap banaye hai
Worth mentioning this is a _class A_ amplifier. It will pas considerable DC current (both through the transistors and speakers) and will dissipate quite a lot of heat even with no signal. As its class A with no degenerative feedback, it will also be non-linear as well as being a current amplifier. Good for educational purposes especially if you can probe it to see how it works, but it will get extremely hot in short order and potentially damage your loudspeaker as well if its not sufficiently rated owing to the large (~1A) DC current that will circulate even without any input, so user beware.
Its also Mono? Is he sending both channels into 1?
@@johnnyboy2459 It looks it. Basically the transistors are hooked in parallel with ballast resistors.
many thanks for the warning. would have been a very costly mistake.
Ficou bem explicado o projeto!
E a montagem de cada componente seu devido lugar(simétrico)fez com q o projeto ficasse espetacular!👏
Diferente de muitos outros projetos em q os componentes ficam tudo embaralhado!
Parabéns👏👏👏
O que significa "DCO" ?
😊okuhjnk@@danyelnunesrj
Desde ESTADOS UNIDOS 🇺🇸🇺🇸🇺🇸.gracias por compartir con nosotros tan hermoso proyectos.. ✊✊✊✊✊💪💪💪💪💪💪💪
Parabéns pelo vídeo, bem explicado mesmo sem falar nada e projeto bem organizado, muito top.
Ржу, граждане ! блок питания 24W, усилитель класс А ,то есть максимум 25% кпд.Получаем на выходе 2 с небольшим W! И это приблизительно с 50% гармоник. Усилок супер! Собирайте.
А каким образов в данной схеме убираем постоянку на выходе? Там вроде кондёр должен быть.
Gracias por compartir tu vídeo buena la información saludos desde México
5 volt for usb player ? coming from transistor ? Not used 7805 ?
The module is equipped with IC 7805. So no need to add it again
Uday Mestry i think he hack brain,where 5v for usb mp3?.?.?
Congratulations on the project, friend how would a project for a 3-channel amplifier, left-hand side and a subwoofer be?
It looks like the 470 uF electrolytic is wired + to transistors, and -- to the potentiometer (wiper pin 2) I didn't see anything mentioning that and it could be important. Otherwise very clear and pretty cool, straightforward, fun easy project.
Super.... But Please make for 2 Separate Channels ....
Nice to see someone doing neat work for a change.👍
i have learnt a lot from this video.
Bhai Bluetooth module 5v pr work karta hai sayad .. aapne 12 volt kis tarah de diya
Nice! The size from the toroidal coil doesn’t matter?
spectacular project.
question.
What is DCO, and why is its use not continuous?
Iam watching from india 🇮🇳
I liked the excellent setup. simple pasta congratulations.
Done wonderfully finishing sir, can I connect with computer and television, if yes, then how can? If no, plz upgrade this project. Plz reply sir.
Projeto muito bom e fácil de ser montado parabéns
انت مبدع ،،،انت شاطر ،،،استمر بالابداع
Mano ficou muito bom voce superou bom de mais a musica ficou linpa sem ruidos ficou show
No entanto a potência é muita baixa e a eficiência também.
Cade a fonte nao tem fonte ligada
Agora eu vi a fonte
This amplifier is stereo or mono
Good morning from Germany
From Iraq ILoveYou,المزيد من الفيديوات لطفا.
Very nice
Can you explain what are the part and how they work together ,so we can better understand and learn
Cuidado !! Si los voltios que exitan las bases es mayor a 0.5 vol, circulará corriente continua en los parlantes y se pueden quemar, la resistencia de 1kohm tiene que ver en eso.
Y como puedo evitar que se quemen los parlantes disculpa te consulto xq no mucho de eléctrica estoy comenzando
@@arielzapata7062 usa un diodo entre el emisor y la base, ese te mantendrá justo a 0.54 vol la base.
Muito legal parabéns
Nice wake up device :-)
0.5 /5w resistance ni py dusara Konsa number Ka resistance laga Sakta hy. Sir plz reply ..
all those components are from an atx power supply?
First of all congratulations for the simply sensational video 👏🏽👏🏽. How many Ohms does the amplifier output work with?
Very good 👍👏👏👏👏
Mantab high power full,bassnya pasti keren,👍👍
Quero ver vc testar com uma caixa completa com graves, medios e agudos, pra atestar a qualidade do som
Vejo que o irmão entende de som. Gostaria que me informasse se esse amplificador desse projeto, dava certo em uma caixa de 15p?
o som fica estéreo?
Excelente tutorial una pregunta se pueden conectar 2 potenciómetros más para agudos y graves? Y poner salidas RCA y de micrófono?
Max output?? It can provide 12 watt??
Sorry, but that circuitry really hurts....
He builds a crappy class a and people believe him
is there any detail for the toroidal coil?
Nice job brother...😍😍😍😋😋😋💌💌💌🎶
can you make a more professional project that can be used as long as you want .. ???
Good
This thing can't be made more "professional"
Yeah I need it too
how with this circuit did you get rid of the constant voltage at the output?
in an amplifier it is very important not to have a constant voltage at the output.
constant voltage heats up the coil even if no sound is coming out.
Yeah, you're right, in the description says it's not for continuous use, since it has a high dc output (I think that's the meaning of DCO)
Would you explain a little more about dc offset dco? And why we should not use this amp for long period of time thanks
Nos explicarias mas acerca del offset y por que este amplificador no se puede usar por tiempo prolongado
how about you use heat pads under the transistors not to cancel eachother out by short on the heatsink? with no pads you have the big steady "negative shine" that heats up the speakers. and you may want a 2 k resistor, lower output but longer life
🎧 एक नंबर 👏🚶🎧
What is "DCO" ?
How many W this project?
It means a good amplifier or "professional" does not delivery in the output DC current only AC, this project delivery DC + AC in the output it will cause heat in the speaker, they are made to work only with AC signals
(D)irect (C)urrent (O)utput
DCO is "DC Offset", the author is warning that the DC Offset is high in this design.
Basically, in an ideal case, there is 0 DC Offset, meaning 0 DC voltage when the amplifier is idle. For a Speaker to work, the output is AC (Alternating Current) and the alternating current flow is what causes the speaker to push inwards and outwards. If you apply DC (Direct Current) the speaker will not move ... rather it will move into position once and stay there until you open the circuit, in which case it will come to its rest position in the middle. This is because with DC, the current only travels in one direction ... so the voice coil will also only travel in 1 direction. Also the DC voltage will be reached and remain constant, which means the speaker will also reach a position and stay there and not move.
The idea is that if you put a speaker on the table, it is in a rest position. This "rest position" is when the speaker is receiving 0V or disconnected and just sitting there. Same thing.
Given the intended circuit is an AC (Alternating Circuit), which makes the speaker move inward and outward, the rest position is at 0V. If there is a bit of stray DC voltage across the amplifier's speaker outputs, what it means is there is an underlying DC voltage that is different to 0V which means that the speaker never comes to it's 0V rest position while connected to the amplifier. The rest position of the speaker is "Offset" from the normal 0V position due to the DC Voltage ... so "DC Offset" (DCO). The speaker never comes to rest basically, it is offset but this also has a thermal implication. The voice coil will generate heat as current is passed through it, the inward and outward movement of the voice coil acts to keep the voice coil cooler. As DC results in current passing through the voice coil but the voice coil not moving, it will not cool itself and is more prone to overheating and causing damage. Everybody has a similar idea as to how much DC Offset they can tolerate, be it 100mV or 25mV but you really don't want to see more than 100mVDC on the outputs.
Gostei do amplificador é muito bom ok professor, Fais um amplificador com 2 transistos 2sa 1943 Ôk
Kayaknya ok bgt, blh dicoba tuh ngerakit sendiri.
12vused. But btutooth board only 5v run how is posible
Whats the inductance of the toroidal coil

Hi I'm nemat from Afghanistan if you don't mind can you make an amplifier that could be used continuously and it would be easy to make
Sir 0.5/5w resistance Nahi Mila uski jaga py Kiya Dy Sakta hy.
Excelente, parabéns pelo trabalho
Its simple en nice job..
Hi Friend
I traying to buy all parts as you mentioned but toroidal coils are not available here. So can you guide me which alternative part can be used.
Pls reply...
specs of toroidal coils?
No caso os indutores seriam simbólicos? 🤔
Very good Bhai
Kitna what ka hai
Buenas tardes amigo con este amplificador puedo mover dos (2) parlantes de 4 ohm de 8" 175 RMS
Excelente trabalho,poderia informar se há desenho de montagem ???
уж луче на полевом транзисторе сделать стереоусилитель
what is the specs of turoidal coil?
Is the MP3 bluetooth 5v input, or 12v input most of the MP3 bluetooth modules r in 5v operation,if it is 5v operating one,how can work on 12v input with out regular?
Great! It Is mono or stereo audio system?
I see it being mono. there's two speakers but they're hooked up together in parallel, being fed from One Source.

Wow nice tutorial
Ficou top nota mil 👍👍👍🔈🔉🔊🔊🔊🔊
hi, what is the value of coil Henry? how many watts of total output? thanks ...
How much wattage output sir?!
Muy buena efectiva..!!!
Disculpa que tipo de cable utilizaste para las uniones
Buenos días si uno quiere le puede hacer una capital para que no balla a ver percance muy bueno esa tutoria
TOP a plaquinha
U r brllnt bro ...
Please ..upload how to make bass and turbo
i sir, where did you get the power supply for mp3 player 5 volts??????
I'm going to try it.
If you want to waste your time
Está chingón,me gustó podrías hacer un esquema,como lo conectaste.
真令人驚訝，如果能改成雙聲道就更棒了!
O segredo está na fonte, que acaba limitando a corrente, em 2A, pois se aplicar uma fonte de maior corrente, o circuito vai drenar mais corrente aos altofalantes, que por estarem em paralelo, podemos supor 2ohm, constituindo uma carga de baixa impedância, vai levar em saturação, com queima dos transistores. A potência maxima deste arranjo, é de 5 watts RMS. Com baixa eficiência....
It is a very low performance emitter follower amplifier and produces a lot of heat that can burn transistors. for a correct amplifier two transistors must be used that is class ab is very high efficiency.
Esse amplificador serve para carro?
sir what is the value of the inductor and what is the rated voltage of the capacitor tnx sir
Una pregunta, soy nuevo en esto y quisiera saber si esos transistores y los demás componentes electrónicos que muestra en el vídeo sirven para equipos de audio diferentes o más grandes
別被騙
Is mono? O stereo?
I make this circuit but when i turned on there is always humming sound comes from speakers when i use the transformer but when i use smps supply the humming goes. But i want to use the transformer what i do...What was the reason what can i do now..
Eu gostei muito eu vou tenta fazer
when you notice that you cannot use continuously How much is the maximum time that can be used?
Until the speaker coil windings burn out.
Sir apne yeh speaker kaha sa liya ....
Plz muje link dho plz
Tengo dos parlantes de un equipo Panasonic que ya no sirve, las especificaciones son:
L/HIGH (3 Ohm) LOWHIGH (3 Ohm)
R/HIGH (3 Ohm) LOWHIGH (3 Ohm).
Que amplificador me sirve?
Q tal amigo disculpa q bocinas son me gustaron en donde las puedo conseguir cuál es el modelo disculpa
Ok .thank you .
toroidal how many henri.?
