Electrical Engineer here. You need to isolate the speaker from the 12V line. Remove the inductor (labeled as coil). Now connect the 12V directly to the transistors instead of through the speaker. Put the speaker in parallel with the transistors, one side to the 12V line and the other to ground. Add a large capacitor between the speaker and the 12V rail with (-) side to the speaker. This should isolate the speaker from the 12V, preventing it from damage. It should also make the audio sound a bit cleaner. Improving on this: Calculate a base input voltage offset to keep transistors in active mode and add a resistor from base pins to ground. It'll reduce distortion.
How?can you modified that sercuit
In my opinion, best he can do is to use two of these 13007 as push-pull topology, not as "quasi-darlington" single ended. It present topology it's easier to get transistors fully saturated, which causes distortion. Second thing is that single ended amps (A class) have less efficiency than push-pull amps (AB class).
On the other hand, testing bass speaker in "free air" conditions is not a good idea. Even a weaker amp can provide some bass if the speaker cabinet is calculated correctly. Enclosure makes at least half of job in providing bass from the speaker.
And the last thing. Wanna see speaker bouncing? Use a real woofer speaker, not noname like this. This magnet looks really tiny, and suspensions of this speaker can be too hard :) Maybe Eminence Lab12?
This guy is an idiot, you NEVER pass DC through the speaker, but he always does!!

your assembly method are inimaginably artistic ,im pretty impressed by the way you placed all component ,
you need to be proud of what you make , and you need to be proud to help the future
im electronic thechnician and all i can say its , wow
thanks , for salvaging component the right way
Gratz from quebec Canada
🇧🇷🙂👍 Legal Muito BOM 👏👏👏👏👏👍 PARABÉNS
This is a Common Emitter design with Collector Feedback. The only reason I can see why you would find the need to put the 3 transistors in parallel is to handle larger currents for stable load lines effects (each transistors can handle up to 8 A, 80W, and 400V).
Also since these are switching transistors, they are not the best amplifiers. Nice project.
I would suggest that you use these transistors in Darlington configuration to get higher hfe values.
I need your knowledge lol... Because i have no idea what your alien language is... And somehow i ended up turning a simple 10 watt computer speaker amplifier into a stable 350 watt setup... Lucky i guess, teach me your ways lol
@jamdvx Increasing the input to too high a level will cause distortion. The standard for input levels to transistor amplifier preamp like this is about 1 Vpp or 1 volt peak to peak.
Done, it works great. It is fantastic, a bombshell. Congratulations nice project.
De cuanto tiene que ser la bocina
Buen experimento para probar y motivar a los que se inician en electronica. Un aporte amigo.
Now I would Like to see a Audio Spectrum, from the Low, LOW's to the High' HIGH's..
good job! Take speaker into bass box reflex for better effect :)
Nice home built mini-amp, how much effect does it provide with that small power-transformer?
How much juice and you use for such small construction?

I'm inspired of this idea on how we can turn our old electronics devices into something great innovations
все просто и красиво ,спасибо вам)
Me gustó voy a buscar las piezas para hacer uno así gracias hermano
Te funcionó??
Hola Muy Bueno tu proyecto amigo, me parece excelente, recuerda colocar el el diagrama de circuito electronico el Potenciometro para que la gente pueda ver el circuito completo. Saludos
mira este video, el circuito es similar: ruclips.net/video/4bJwRG_Hino/видео.html
Cool practice and learning project.
Could I use a 19v 3.4a notebook power supply?
Already working with a 12v 1.5a power supply
The potentiometer I'm using is the B10k and it didn't get too loud.
I am looking for a 100k. Can I add a 12v led to indicate it is on?
That's why I love Electronics Engineering
walter Floriano Está faltando no esquema o Potenciometro,,, Incompleto...
Woooooou this is more than powerful base
Eu posso usar o Phl 825? Esse 13007 vem só 2 na fonte. As outras que abri tem mais desse que citei
ola meu amigos....montei o circuito com 4 transistores 13007 e coloquei como pré um amplificador de caixa de som de pc com tda2822 e o resultado foi muito....e pode ligar junto aos 12v pois o tda2822 suporta ate 15volts e tbm alimentei todos os circuitos com uma fonte de pc.....show
It's like the first amp I ever built when I was 14. Mine used only a single transistor and a 12V adapter. Your coil is not necessary, unless you want to pass only bass, you should use a much bigger coil. Quick, dirty, and effective, but most certainly not an optimal design (DC goes through the voice coil, raising it's temperature).
This is a class A constant current amplifier (no electrical voice-coil damping/control), open loop (no feedback) and direct connected output (no capacitor).
Have fun and be safe!
Replace the coil with a capacitor, and this design would be fine.
@cleber g pereira Spawn around 1000uF - 2200uF. Note, capacitor value will affect the frequency response. The lower the capacitance, the less bass you will get.
A circuit schematic would be most useful... Fair play for recycling electronic components though :-)
Huh? Isn't 6:55 sufficient. And, an up-tick to you for giving him kudos for electronic component recycling. Something more of us should be practicing.
Suena súper aparte de q es muy sencillo hacerlo 👍👍 sigue asi
Thanks, constant current through the speaker. Dangerous!
do not use on any speakers especially expensive ones ... could damage speakers easily due to DC across the voice coil
Parabéns... ficou top o projeto.
The comments section is full of self appointed experts. Lads, he's not aiming for hifi here, he's just showing you a fun little circuit with a few old parts.
well if these people want to keep using the titles that they do then make literally the same exact thing so many other youtubers have done using the same bs titles then they can expect the same kind of criticism
No HiFi but at least proper implementation of low frequency aplifier.
I think it's a cool little project that looks fun to try, but these people are taking it way too serious.😜
@@paulzedx636ninja7 Maybe the project is cool, but when some young person with not so much knowlege try to do it, and burn down its audio source (phone maybe) and speaker (transistor short circuit), that video is becoming a very bad way to learn electronics. This circuit is high ineffective and in some situations its could be even dangerous.
You could literally use the exact same parts and make something that sounds good , if you build it correctly and not just slap stuff in the wrong places. Never put DC through a speaker. Efen just using an inductor in the collector would have worked better, look up inductor class A amps.
So many questions... I have very little understanding of componetized electronics... Always wondered how to do a simple amp like this... But why not use a cap and resistor per transistor? Like i said, i have very base line "youtube" knowledge on stuff like this, but it'd be my understanding that the sound wouldve been cleaner with less distortion if each transitor had a cap and it'd change the hertz of the sound range per resistor used? Am i correct to say you should be able to have used as many capacitors on a device like this and it'd just help carry a load without constantly pulling power? As in that it wouldn't effect anything other than it's ability to have power as it needs it withou constantly pulling "fresh power" from the battery or the power plug?
That signal could be filtered to get more performance?
what about a BC212L driving two 13007 or BD131 transistors.
to milai
Hi: Tengo todos los componentes que se necesitan, pero solamente 2 13007 y 2 BC 548C, puedo utilizar uno para llegar a los tres que solicita el circuito, utilizar los 4 ? que me sugeris. gracias
Hola broh pasa pasa por mi canal tengo lo q necesitas hacer.
A couple of things...
18W max @12V (1.5A x 8ohm load) With a 4ohm speaker you would double the current and wattage, also if you use a voltage doubler or boost power circuit you can get more wattage. Of course all the components would have to have voltage ratings to support higher voltage and proper thermal heat dissipation as well.
When bridging the output of transistors to split the current amongst the transistors, you must send the output of each transistor through a .1ohm resistor to account for the variables in manufacturing of the transistors.
Only a positive voltage can be applied to the speaker. This would be considered a push amplifier instead of a push/pull amplifier that can also apply a negative voltage as well. A speaker can push out and also pull in to match the waveform of the music.
I am not an electronic engineer but have been repairing electronic, electro/mechanical devices for 40 years and I am certain there would also need to be other support components to create a quality signal output and efficient amplifier.
Sem considerar a eficiência do amplificador classe A, ou seja, 50%. 3.1 / 2 = 1.55W. Without considering the efficiency of class A amplifier, that is, 50%, 3.1 / 2 = 1.55w
Very clean and good work bro,
Excellent video.
This is a class A amplifier, wrongly designed.
The transistors work "saturated" so in the loudspeaker constantly passes a voltage equal to (Ucc-0.7) volts, which will lead to its destruction.
In order to be functional, a correct polarization of the transistors and an impedance adaptation with a transformer must be made.
Hey It looks like you know a lot about amplifiers. I made an amplifier as well so check it out my channel name : DIYkING 9K
amazing work!
i bet you love that old soldering iron so much.
Lol that's gonna always be look like that no matter we love it or not.
▬ Esse tipo de amplificador é só para iniciantes em eletrônica. Funciona, porém há grande desperdício de energia na forma de calor tanto nos transistores como no alto falante, além de por este em risco, caso opte-se por uma fonte mais potente e os transistores venham a entrar em curto por aquecimento. O resultado será a fonte descarregar toda a sua energia no falante e, caso demore-se a tomar uma atitude, a bobina pode vir a queimar por aquecimento acumulado.
Meu conselho é que façam a montagem apenas por didática, testem mas evitem usar no dia a dia, e aprimorem-se num projeto só um pouquinho mais complexo, tipo com mais alguns transistores, que dê maior rendimento e mais potência. Há diversos projetos simples com transistores e/ou circuitos integrados de cinco pinos e poucos componentes externos, dispensando, inclusive, uma placa de circuito impresso.
Tá faltando o capacitor eletrolítico e o potenciômetro no seu diagrama.
Não ta não.

You can find it in the PC power supply
Strange how a speaker works with DC voltage....that circuit looks like a simple boost converter, not suitable for audio signal boost...
It doesn't, not for very long, anyway.
Hey man, very nice. But how do you know what is impedance out? Thanks for now
What's the output power of this amplifier in RMS? And what is the impedance of the loudspeaker??? Greetings from Brazil.
Ottimo sistema per distruggere l'altoparlante che è sempre attraversato da continua. 6 volt su 8 ohm quasi un amper di corrente sulla povera bobina.
In realtà l'altoparlante si comanda in corrente, vedi un classe A o un classe AB, o semplicemente un collettore comune
Una pregunta amigo tengo todos los conponentes pero el transistor que canbiaste x otro estaba malo o los 3 tienen quewer iguales responde gracias

Pra que serve o potenciômetro? Se eu não vi ele aumentando ou baixando
Acredito que ele deixou na potência máxima já... mas obviamente que o potenciômetro serve para baixar ou aumentar o volume!
👏👏👍Consegui fazer, mas esquenta muito os componentes.!!!
Mano o segredo é o dissipador de calor. Eu acompanho os projetinhos desse cara há 2 anos! E todos que fiz até agora deram certo. Tem uma semana que to curtindo esse projeto no meu subwoofer de 350w rms, e tá só filé! Curto com mais 3cx ligadas em outro amp, separado. Já curti por 2 anos seguidos com outro de 2 transistor. Um dissipador aumenta a vida útil deles. Bom tunts tunts ae! ;)

Na montagem ele liga o + do capacitor na base do 2º transistor, no esquema ele está ligado à base do 1º junto com o resistor. Tanto faz?
That's interesting! Apearantly easy to do... but I guess it needs a preamplifier... so, for two channels, 6 transistors are needed right? And it gets more complicated then... anyways, I'll give it a try! Thanks!
1,000% THD ;^)
Gostaria de ver mas montagens com explicação em portugues falado ou legendado
Mais o vídeo é gringo
tem videos brasileiros sobre o mesmo assunto,porem nao se usa bobina e se usam 2 transistores
A bobina é pra tirar os ruídos e não deixar o volt ir direto pro alto-falante 🔊
Copper coil size..?
U make complicated things look very easy.. Thanks...
Me acustado mucho el video , pero me gustaria saver si levantara dos bocinas de 100 wats RMS?? O rrecomiendas otros transistores que vayan intalados de la misma forma?
Where's the potentiometer in your circuit diagram?
look this video at 4:03, the circuit is the same : ruclips.net/video/4bJwRG_Hino/видео.html
@AKM REVOLTS i think this not functional, because you need more than 12vdc
it may be strong but the sound is not clean
where in the circuit would you put that?
also, how would you know that the sound is not clean? the speaker isint even in a box. speakers always sound a lot better once you put them in a good box.
@@adamhosseinei8631 Because we've seen the schematic. This will be distorted. Also will put DCcurrent through your speaker, which means it will lower performance and maybe even damage the speaker over time. Happend to me with similar circuit...

I did actually follow your steps and I herd a spark from the speaker planit audio
You'll have even worse results if you follow yewtube videos about audio or electricity. Stay away from these sources before you get electrocuted or break down everything around you. Learn electronics from real, accountable sources like books or schools, not from cheap shit.
Increase the supply voltage to 400v and it will improve the bass response although only for a short time 🤔......💣💥🔇⚰😂
haha fireworks on the way
you are asshole? 400v? wtf?
And blow the ass off the transistors 😮
You put DC voltage on your speaker coil.
I assume it's just a simple class A amplifier
Merci beaucoup , c'est très fort
hey can i use a 10k potentiometer instead of the 100k one?
Building an amplifier out of nothing.. thats what this is all about.. its not about. how good and how bad the amplifier is.. Think!

Full range amplifier. No crossover, can hear full frequency range from the speaker. Bwahahhahahahha
Chris Bourassa the Toriid coil in series is a low pass filter but isn’t calculated for crossover freq., it’s whatever it ends up. that’s a extremely large coupling capacitor I thought he would filter power with it . The pot could be tied to ground or center instead of open.
I haven’t ever seen supply voltage to circuit fed thru the speaker before. So I’m with the person making top comment of 100% fake project. never used beyond proof of concept
Dave Zimmerman yea, 1,000 uF? I was thinking smoothing cap for the DC supply for sure, not coupling cap. I would have thought no more than 100 uF at the most. Wouldn't a cap that big lose some of the high frequencies without a smaller cap, like a .1 to 1 uF, in parallel with it? I have lots of circuit diagrams of audio amplifier circuits, one high power one with 9 complimentary pair amps in parallel, in class AB, and it only uses a 1 uF input cap. Granted it has a long tail pair differential amp input stage and two additional amp stages before the 9 comp pair output stage, but still. This amp just seems to have sound quality better than I would have thought it should have for no more than it has to it. Also would 1K bias the transistor bases where they would need to be for a proper quiescent point without cutting off the tops of the loudest waveforms in saturation, or the bottoms below the cutoff point? This looks like a common emitter amp setup, but I would have put a load resistor on the collector to the positive supply, a couple of coupling caps like a 1,000 uF and 1 uF for a small speaker like this, or a 4,700 uF and 1 uF for bigger speaker(s,) on the collectors to the speaker(s,) the speaker(s) to the emitters, a biasing voltage divider on the bases and figured out what values it needed for a good quiescent point, and I might have even considered a low value emitter degeneration resistor and bypass cap to trade a little gain for improved stability and linearity of the amp. Of course I could be wrong, my knowledge of electronics and audio amps is limited to what I've read in books and online, I haven't taken formal classes or anything, it's just a hobby, but this amp though meant to be a piece together from old parts, just seems too good to be true, to me.
The interesting in this project , is that he is recycling the materials from an old PC power supply that's a plus for the enviroment . Good Job VN TECH !
Three transistors in parallel... only one works, the speaker wouldn't support the continuous current... this circuit won't work!
It's a friking darlington bridge! not "three transistors in parallel"
Esse ficou foda 👏👏
Good👍Good👍Good👍.
keep away from very basic design ampli such as this one,this is very unstable,hi distortion,and will destroy your speakers later.
in this case it won't take too long, given the significant DC on the output!
These are not linear transistors, they're designed to switch rapidly, so the distortion is about 10%. Also "powerful" is not a good description, with a 12V power supply and an 8ohm speaker, you should get about 4V RMS voltage, current will be 0.5A and your power will be 2W at the absolute maximum. Ok, it might be 4W with a 4 ohm speaker. That's not powerful. And since music has drumbeats and similar surges, you wouldn't get more than 1W, really. So, what you have made is a 1W fuzzbox.
I suppose if you have an old power supply and nothing to do with it and you're not fussy about all your music sounding crappy ...
dude you're cool with your tips. But his technique works.
@@electromechanik4740 I don't call it working if you really can hardly hear a note.
