- Опубліковано 9 тра 2022
- This project is made for testing purposes only.
This is a class AB amplifier. In this amplifier, 40 transistors are used for 1 channel in the output stage, 80 such transistors are used for stereos.
The driver stage in this is made very powerful.
In which the same output transistor used 3 pairs, which gives strong output.

Ez asztán egy igazi erőmű!👌👍👍👍👍👍
Me encanta wowww un súper amplificador
Michael B. You're perfectly right. Even look at his configuration of pin 2 and 3 of the IC. How can you connect a feedback resistor to pin 2 which is your input and expect that amplifier to work.
from indonesia ..whatching you sir. ..
NINZURI INANGUVU YA KUTOSHA
Super!🙂
super drivers ..very very nice
Nice 👍
Mantap..
Mantap micinnya.. Sakarepmu lah..
Ora sisan 20.000 Watt ...
😂😂
Tuionne
Good job
it is worderful
That heatsink is not lying
Eu quero muito construir está potencia ,,,
Very good work
Keren
Very nice. how to capacity the capacitor.& How to watts the transformer pls ...
excelente amplificador cual es el diagrama de este circuito
Collector directly and Emitter via resistor should connect with at least a 14 AWG wire rails. The wire used in video is too thin for the high current demand. If full load is given with proper power supply the wire will get hot and there will be a considerable amount of loss because of the thing wire rails.
Los transistores no van atornillados?,,,,falto digrama
Ha ces pour grillé les tartines ou les haut-parleurs ?
You mean 3 pairs of output transistors. Tripple Darlington?
Tu amigo Hilario grasia
How much the amplifier assembled 4000watts or up
Merci. Svp donnez nous le schéma de ce montage.
4000w sao nghe âm thanh 40w.demo không rỏ ràng.
Muito bom mas pra eu fazer tem que ter o desenho
Sir how many ampere is needed for this amp and watts for the power supply
It already says 90v+&90v-, the amps come from dividing the 4000 w by 90 v, but we must take into account the heat losses, in class AB, 25%, so in reality they are just over 5000 w.
this one circuit dlagram ple ?
Muito lefal
BUENO SERIA CONTAR CON EL DIAGRAMA.
4000w with 20 AWG cable ?
yo digo que no da mas de lo que la fuente no da pues es en 90+- un total de 180v que tanto el voltaje y el amperaje es importante además los 2sc5200 solo soportan 16 amperes La fuente para dar esos 4000w necesitara un transformador muy grande y costoso y ni hablar de amperaje el mismo ampletos dijo que la potencia no va a ser mas de lo que no te da la fuente de alimentación Hazi le ponga 100 pares de 2sc5200 y 2sa1943 o ttc o tta lo máximo de amperes a resistir son 16 y la configuración necesita más de lo que no soporta 🤣
sir can you do actually a test on that circuit? plus keep in mind no matter how many pair of power transistor is not going to provide 4K watts class AB can not go any more after it reach 850W
but class d amps can reach 4k watts? how many volts and amps to reach 4k watts? thank you
@@mcmanlapaz7880 Since then the power formula has never changed and basically this also applies to audio. P = V * I . So please just measure the output using an AC Volt meter and an AC Ampere meter. Use a signal generator at 1 kHz, so that the signal is constant..
@@DenisIswan-go2uh Thank you sir
Pode sim, tenho montado amplificadores classe AB com 300 VDC (150-0-150) chegam fácil a mais de 2000w em 2 ohms.
el diagrama d la draiver alguien lo tiene
Circuts
QUIERO RESTAURAR MI AMPLIFICADOR CS 800 PEAVEY
90+90=180V, 4000W/180V=22A, What is the cross-section of the wires should be at such a current? I won't say anything about acoustics. It looks like a beautiful fairy tale. And don't talk about Class B. This is a parody of Class AB.
Jal jayega😂
Diagrama?
it will not be possible to issue such a large rms it needs to be tested using a dummy load and an oscilloscope up to the limit of the clip
this using for? if for home..its so over...i think 100 to 200watt is enough
Sir circuit diagram
Ekspektasi 4000 watt
Realita 400 watt
4000w RMS impossible using +/- 90vdc
I think he just use it to test because me too I know about amplifier this should have high and low voltage the resistance is not big enough the low voltage is 90 vote DC +/- with gnd why high should be 220 vote DC +/- with gnd if you do so I can believe is 4000wats this this you do is not up to 1000watts because the resistors will have problems when you add up speakers
😂😂😂
90 V DC means +/- 45V. Max handle will be 43 'cause of 2 x 0.7V Diodes form the transistors. Divides by sqr(2) means 30V for RMS. So P = 30V² / 4 Ohms = 225 W. Never 4000 W!! For 4000W you need around +/- 180V
Depende de la impedancia que conecte a la salida; pero quizás se refiera también si haces dos para stereo.
He said Not RMS but PMPO
Wiring diagram scematic
klas ab?
4000 watts? te refieres a 100W? eso no va a dar 4000W
Da 2000,4000 en stereo.

No clear testing demo
That Sound doesn't look like even 100Watts

90 volt DC is possible

Cape
i think its pmpo not rms...
Magkano 4000watts mag bili sana ako
dia garam do
LES SOUDURES A REVOIR ET LE REFROIDISSEUR TROP PETIT. CA VA PETER APRES 5 MN
Untuk mengetahui daya sebenarnya pakai dummy load 2ohm 4ohm atau 8 ohm ukur output dengan osciloscope, lalu input kasih signal 50hz-100hz, adjust vol sampai menjelang klip, lalu hitung daya real nya..
That's no 4000w. It's maximun 800watts😂😂😂😂
Prove it's 4,000 watts rms put it on an amp dyno live. I'm being it's nowhere close
Holy Crap! The use of 2 diodes in series to set an idle-current is technology 40 years ago. You can hear the distorion in the speaker. THD around 1% is normal with that. Every class-d amp will do the job better than this crap.
Haha,,,,I saw that too.
without oscilloscope tests, ampere pliers, dummy loads it's all bullshit
😂
😂😂😂
This is total crap, click bate. It's so easy to put loads of transistors on a bit of metal that would not handle 100 watts and claim 4000 watts, now prove, it, try using some test gear. Of course, you can't, but lots of people will be fooled.
Yes Mike, worse than crap, if the platform had anyone who knew electronics this BS would be taken down.
Another joke amplifier. Assuming 70% efficiency at 4,000 Watts output you will need a power supply input in excess of 5,000 Watts, there is no mains outlet that can supply that much power.
And don't get me started on the size of the heatsink.
sounds horrible at the end. what`s the point?
Sir circuit diagram
