yg di video nilai coil brpa uH bang?ingin buat soalnya simple
Jangan bang... Spiker kanan kiri keluar tegangan 12 volt
ياريت لو تضع خارطه تكون لنا اسهل في الصنع
وماهذه الملفات الحديديه واين نحصل عليها رجاء
I built this circuit to try it. It does work and it sounds pretty good. However, with a 1k bias resistor at 14Volts, a transistor with an hfe of 30 will send about 400mA DC through the speaker coil! There are better ways to drive speakers.
Recommendation for you guys:

olá, por favor, você poderia me dar as medidas da bobina toroidal ... obrigado pelo vídeo de sucesso
Yo no sé nada de esto pero admiro el trabajo limpio y ordenado, en pocos videos he visto eso, la mayoría solo quiere impresionar conectado a lo loco y desordenado, felicitaciones excelente trabajo 👍
Está buenísimo. Saludos desde Perú 🇵🇪
Excelente trabajo amigo, gracias por compartirlo, saludos desde Venezuela...!
Olá pessoal, gostei do som no projeto, parabéns CBZ
Привет, ребята, звук в проекте понравился, поздравляем CBZ
\i liked the sound in this project Congratulations CBZ.
Super bass wonderful idea thank you.
D718 has a maximum 80 watt collector dissipation (with maximum collector current 8Amp) and as shown in a video 12 volt wall PS is a limiting factor. My guess that wall wort is rated at 12 volts @2 Amps. Assuming equivalent split between left and right we can expect DC input power of 12 watts per channel. For class AB biased transistor operation that offers a compromise between signal-to-noise (SNR), low THD+N, we can expect up to 65% efficiency. As shown, probably around 7W of audio during bass passages is being kinda generous estimate. A schematic should have been shown at the beginning of the video.
7w max yes if between is max too. According to this arrangement, the level between is the headphone output so this is not the case. which I think power output for sound / speaker is very small around 1 w.
scam !!!
lo felicito por construir este potente amplificador , me gusto mucho es muy sencillo de fabricar
Não entendo muito mais acho super bacana o trabalho de vcs 👍👍👍
Sederhana kitnya suara oke punya...lanjutkan mas...sukses slalu
En caso de q no encuentre el transistor D718 cuál más me recomiendas
Big project. I would like to know what specifications the toroidal coil should have? thanks
That toroidal coil has not specification or any smbols?
Excellent!!!
o melhor projeto de amplificador que já vi !
o seu ficou alto ? o meu ta muito baixo com 12v
boa noite meu amigo. gostei do seu amplificador. parabens
Waw. Tutorial. Nya. Keren. Mantul. Mantap❤❤❤
É o melhor que já v, excelente.
check the Output where the Speaker connects is there any DC voltage?
Hola gracias capo muy simple y bien esplicado genio
parabéns brother 👍
Excelente!!!!! Montei aqui no Brazil e funcionou espetacularmente . Obrigado cbz.
Como você soldou o capacitor no potenciômetro , negativo ou positivo
Muito bom e fácil de fazer para iniciantes
What is the Henry value of the torrodial coils?
Funciona, pero se calienta. hay que poner un fan cooler?
Nice 1, I wish you all the success.🙏
What function the inductor?
Very good bass, mid and treble (thank you very much)
TIENE MUY BAJA POTENCIA, TU COMO LO HICISTES PARA QUE TOMARA MAS VOLUMEN?
Not mentioned, how many dc voltage can be fit with the said circuit???
wow i liked it a lot
Mantap Wak moga sukses selalu
mantap bang totorial aku sangat suka sama vidio abang
Itu toroidal coilx ukuran brapa ya
What size inductor should I get if I were to build this?
Elinize sağlık, mükemmel, basit bas-tiz kontrol yaparmısınız buna ilave ek olarak 👏
Wowwww it's cool
I wil tray at home
fiz aqui e deu certo... mto obrigado por compartilhar.... valeu e sucesso pra vc.... from Brazil.
Sou meio leigo, mas é pra qts ohms e qual a potencia do falante?
@@rafaelm.ramalho8974 cara... coloquei falantes de 6...4 ohms... a potencia nao sei ao certo...mas varia mto com a CORRENTE da fonte... tipo... 12v 1a... distorce.... ai usei uma de pc... 12v 15a... ficou bonzao..... coloquei um cooler 12v encima dos transistores...pois aquece bem..... ai ficou legal mano.... blz... nao da 500rms... mas pra som de casa... ficpu zero bala... uns 20...30 rms de acordp com sua fonte.....
Boa noite não sei ao certo o que eu fiz que o volume não abaixa aos poucos quando ele abaixa de uma vez o início do volume já está bem no final do giro do potenciometro
Awesome, I have multiple IRF 504 transistors, do they work instead of too d718 transistor?
@cbz proyect Excelente Video y aportete felicito buena construcción del amplificador y todo entendible, mi pregunta es la siguiente: de cuantos watts, Honmios es el amplificador, y como se pudiera aumentar la potencia con mas transistores (D718) de los que se usaron en este amplificador, Espero su pronta respuesta, saludos desde venezuela. Éxitos en sus proyectos.....
Mantap jiwa bos..
Excellent One
Manteb juga praktis
Nice amplifier bro
Ultra bass 👍 karya wow
"A" class power amplifier, simple and very good!
That's so cool !
Thanks friend..
Bhai coil ki jageh kuch Orr laga skte hee
woow great job
who's with me here
Beleza pura, e so encostar o auto-falanten na beirada da mesa que os graves resonava bem melhor. Parabeens!
Beautiful tech
Can i use capacitor 470uf ad 10v ,thank you
SIR, I just make this amp one side and it plays clean and nice I love it now I would want to go bigger with this setup
It works properly or not if i used both 22 k potentiometer??
Where did the ground hook to from power supply
It works properly or not if i used both 22 k potentiometer??
al conectarlo la bocina se pone rigida cual sera el problema gracias
Excelente!!
Muy bueno !!! Me gustaría saber de cuantos Omhs son los parlantes ,4 ,6 , 0 de 8 omhs ?
Muchas gracias
Respect you brother I made it and I won, very nice
Really
how many Henry for the inductors?
posso substituir os transistores e colocar o 2s1943 e o cs5200 e manter os outros componentes
Good job
Muito bom 👏🏻👏🏻👏🏻
You can tell me the dimensions of the toroidal coil core.
Thank you
Very nice pro
Qual as polaridade do p2..ficou confuso..terra saida 1 e 2!!! Qual as pontas de fio são referente?
One or two transistor power is not suppicient strong outpot..good differincial and powerdrive transistor then 4 transistor boost up audio out..but still good job sir congrants..
Cool Man...
hola muy buen trabajo, pero ya en la etapa de salida se podria colocar un condensador para filtrar la corriente continua no se digo yo pero esta buenisimo
sir ji Toroidal coil nhe h uske jgh kya ush kre
Та самая сборка что я искал бро !!! Спасибо !!! С маня подписка и лайк ;-)
Подскажите пожалуйста, между радиатором и транзистором что он подкладывает?
@@prizrakdiablo1263 термопрокладка. можно использовать слюду, или только термопасту и обязательно изолировать радиатор от общей массы(ну если это будет усилитель с коробкой)
i like it
nice video
Achei bem bacana!!!
Qual a potência, quantos watts?
Joao Alves gostei do teu trabalho.
Capacitor de 2200 igual anda?
4558 ic low pass filter kaise bana sakte hain 0-12 1amp transformer
That is really amazing with just 2 transistors..
Uma dúvida me surgiu....
Até quantos alto falante Bass pode colocar e quantos normal pode também...
Por favor me responde, forte abraço gostei do seu vídeo !
very nice
Whoich type spkr u use?
Can u make a 8k class d your self cheaper than it would be to buy one
Muito bom!
Perfect
Son de esos amplif. Que se escucha el paso de la corriente en el parlante?
Why would anyone do this? This is class A amplifier, this is only used for transistor preamplifiers. The efficiency is poor and you have a large current thru the speaker in idle. Not knowing the actual current thru the speaker can burn it easily. Also the membrane is not in its ideal position in idle. Buy some $2 D class amps on net and you'll be fine.
Well said.
can you share your work?thanks
Of course right. But why would anyone would do this? Because it is fun.
What I don't really understand is, why is the placement of the cone Not ideal? And why is there any current in the speaker in idle?. No voltage, no current. Don't mix up the quiescent current (DC(!)) which is blocked by the decoupling cap, with the AC current of the audio source, which is driving the speaker.
So in idle state there is no current in the speaker coil.
Edit: I am sorry, I wrote my comment before the end of the video. It is this cheapo amp version without decoupling caps in the output and the plus lead of the supply directly at the speaker
@@thomasr.5443 I just wanted to write a reply and I saw you fogured it out already. I totally agree, it is a fun project for hobby and learning, maybe even useful if you urgently need something and don't have many parts. Good thing is, that almost anyone with a soldering iron amd some scrap parts can make something useful and learn on the way. But for real use... No.
@@slavric absolutely.
Good job ,good Vidio , success
Thanks friend..
Excelente amigo grasias lobo ayebar acabo grasias.
Can i use with a blootooth adapted?
Very nice design 👌
Thanks friend..
MUY BUENO , LO HARE GRACIAS DESDE MEXICO
No funciona, ya lo hice
@@silvioalcantara.colorado2499 SI FUNCIONA SOLO QUE LO ESCUCHO BAJO DE VOLUMEN Y SE CALIENTA MUCHO EL DICIPADOR
Esse amplificador dá para fazer com transistor 13007 ?
Hi.that's the potentially what's there amplifier ?
Sir apke pass jo 6 inch ka speaker uska link dijiye na plz
I want buy this plz sir
Humble request
Muito bom 👍👍
Super and super
how many turns in coil ?
Bhai trangestor d718 kha se mala ga or kitna pris haa
excellent
A cuantos Wats quedaría x cada salida de audio?
