ES INCREÍBLE QUE YA HACIA EL FINAL DEL 2020, un canal con más de 200.000 Suscriptores, siga haciendo barbaridades como esta, siendo que lo más fácil hoy día es mandar a hacer los impresos, hay empresas con PCB Way y otras, que tan solo le pasas el archivo por correo, luego ellos te dan el presupuesto y te hacen ofertas y hasta mandas a hacer varias, cancelas y dependiendo en que país vivas tienes tus PCB's super pavos en x cantidad de días, creo que últimamente la elaboración de dispositivos en estos canales están quedando muy mal, porque te hacen ver que no está mal hacer cosas machacadas siempre y cuando funcionen, y actualmente hay es que enseñar que hay que hacer las cosas bien y con los materiales adecuados, PARA QUE FUNCIONEN BIEN...!!! ME DISCULPAN PERO ES MI OPINIÓN, NO VEO NADA BIEN HACER UN MONTAJE COMO ESTE QUE VA A MANEJAR TANTOS AMPERIOS EN UNA PLACA PERFORADA EXPERIMENTAL...!!! Y QUE CONSTE QUE ESTOY SUSCRITO Y HASTA CON CAMPANITA ACTIVADA, PERO LA VERDAD NOS HACE LIBRES...!!!
Saludos . Como se calcula la potencia de un amplificador y como se protege .
Show, muito bom o projeto da fonte.
Muito bom!!!
That' s very cool ..building amplifier power supply at home
This is an incompleted project ,you must add a layer of protection for your bridge diodes,They can sustain a limited amount of peak current,When turning power on,there is a large in-rush current pulled in by the empty capacitors.Those capacitors have a very low internal resistance and so your power transformer .In-rush current must be limited at turn-on.One easy way is if you add in series with the center tap a 1 ohm power resistor (5 to 10 watts)(it won't affect your load current) if you have a 25 volt supply, V=RXI our I=V/R 25 volts divided by 1 ohm= 25 amps,if you don't ,it will be 25 volts divided by .1 ohm=250 amps. This will last a few milliseconds,but over time will fry (short) your bridge diodes .Ac will then be sent to your capacitors and blow them up.
Some will install a larger resistors (30 ohm) in series with your + and - capacitors terminals thus limithing the charging current .Those resistors are short circuited by a relay contact after 60% of the charge is reached.
Wish you luck.
Bye.

Thanks for your comment. please also visit here www.electronicshelpcare.com
can you send me a diagram explanation..
thanks 👍
bien los toroidales sigue impartiendo tus conocimientos soy de peru
Awesome works ı watched lots of your videos but please use different musics.This will enrich your channel. Keep going good job
i like the music background.,.,

Boa noite muito bom diferente ok abraços
Can i ask the components you used sir also the name and value
Freundlichkeit, Idee nicht schlecht las das besser erfahrene Machen
ideas brother
i'm from in cambodia
Hi bro
Good work brother
parabéns pelo projeto ,.....mas no video aos 7:27 tem dois capacitores ao contrario confere.!
opa ricardo acho que voce nao observou bem o circuito do banco capacitivo ,alguns capacitores estao em serie
I like this video kya app assembled amplifier kya price me hum ko bech sakthe hai aap ka contact no my try kara vo nahi milrahai.
Hamare se lelo
Gd am bos pagawa ko sana amp ko mtagpoan shop m?
Vi ai transformar volt koto are A mph koto or prize koto
Beautiful...
Nice work
Nice backsound music
Y esa conexión así que diferencia hace en la normal ?
Tnx for uploading this video
Nice video sir
tnx
sar ji aap se thoda baat karni hai aapka Kiya Gaya PC bhi humko samajh nahin aaya to let ho raha hai aap samjha dijiyega to bahut achcha hoga
Can you tell me why mine attacks me when I turn it on.......
lol
nice but long vidio
Buenas tardes un pregunta que modelo de tránsitor es y marca
Utiliza unos 8 condensadores electroliticos, 4 puentes de diodos y un transformador toroidal, no creo ver transistores...😅
Nice video good idea 👍👌.
I have 0 -12 volt 75 Amp transformer. Please give me details vwhich bridge rectifier and no of capictor and value to be used. Thank You
very high
Hay un error en el min 9:52 con uno de los condensos
entonces no sirve?
a decent size transformer

Nice video

Good work & neat
u not show the capacitor volt n mfd nd coil transformer volt ac n dc
No se ve la medicion por la grafica que sale, que pua....
Esse e o comentario br que vc procurava? Kkkkkk
Amigo me gusta tu trabajo y tú video pero la música que pones de fondo es astiadamente aburrida
Nice, but this is just a power supply for amplifier. Not complete amplifier circuit
Watch the naxt videos
Logisch
Nice bhai
What song?
Berarti volt dari trafo 80 volt
vi apnar basa kotai..
يخرب بيت دماغك،،،، ماشاءالله
Alguém pode me falar sobre esses capacitores usados?
É semelhante a uns que vi no Aliexpress, os que vi se não me engano a marca é HCG.
Pela capacitância, se tiverem qualidade compensa importar.
Nur richtige Anwendung alles gut
pienso que gasto soldadura demás con solo cable de calibre 18 o 16 hubiese interconectado
Can i known more abut the power amplifier please this is my number +2348113767482
sir capicitor kon sa use karna hai
plz bataiye .....
super amplificador
Вы куда смитрите одна фазник плата

E có bo nguồn như này tụ 63v 15000 uf thì ac vào hv và lv là bao nhiêu vol ạ
Falta la prueba de sonido
Super but very long video
Transistor amplifier are Outdated / Buy IC 4440 amplifier
Ic out dated. Hi hi. MOSFET amp better than ic amp
Bhai naam bhi kis ic ka lia 😆😆😂😂
reques please make a 400watt amplifair so you can lift the 15in speaker
Hello
Power transformer
Can use the "super cap" to replace these "E cap"?
nice
Capacitor rating
chhoto bhai ki boba naki?
Verry good
DIY PSU CLASS H?
Old and heavy and noisy power supply. Just buy online smps for audio amplifier its smaller and lighter and a lot more efficient and powerful.
all people can't buy brother.

А нормальную схему заранее нарисовать ума не хватило? А ещё в конце ролика ссылка на видео, прям на экране мультиметре. Но я и так знаю какое там напряжения. АС "действующее" напряжение умножается на 1,41 получаем DC "амплитудное" напряжение
Cost and India me Kia delhi me milega
Vi ka apse bat kare sakta hu
не правильно.
я заметил ошибку.

Secondary winding how much voltage sir...
Test to karo
Your location please
cant se the reading because of the pioneer vs kenwood ads :-/ maybe move it a bite
😂😂😂😂😂😂😂
Das geht anders,und ohne Dioden schon gar nicht

How much amount to complete this Amplifier
Very nice
Your nambar
you are violating the rule by making an 90 degree bend in your circuit

Another confusing "I can't talk" & "I'm not going to tell you objective steps". For gods sake slow down & offer some explanation, including why you appeared to destroy an old amp.
Iska price kitna parena, transformers ka
TURNED OFF VOLUME. SO ANNOYING!!!!!!!!!
high power my ass stop scamming us
jajajaja jamas puso lo que se ocupo pa armar su mamada esa
Soldering with a screwdriver tip??? Are you too poor to get a real one?
André Fréchette he’’s just showing how skills and creativity he have,😜
@@rommelcayabyab7825 he didnt make an amp he made a power suply its not creativity but stupidity
Nasty dangerous junk. If you are going to use copper matrix board at least use insulated wire not lacquered. The wires are too thin as well.
tnx
