DIY Powerful Ultra Bass Amplifier 4 Iron Transistor 2N3055 , No IC , Simple circuit 

The only way to measure power accurately is across a fixed load and a regulated power source and then a signal generator and a good scope. It will tell you everything that you’re ear’s won’t! And it’s as good as you’re going to get with the test equipments calibration for error. Some 2N3772’s for the 4 output transistors, along with a 2SA1516 in place of the 2SB688 would help up the gain and output ratings. Use some higher wattage resistors on the emitter shunt and you’re golden!

Just an electronic hack dudssss, they're hacking it, for they're genius 💪, now you know...keep sharing guys... hopefully with tone control

This one of those vintage amps which seem to be quite popular now.

One of the better comments for this video. Direct and to the point. Now that deserves a thumbs up. 😎🇨🇦

सुपर बास 🙏❤️🙏👍

Totalmente falso ..desimformas..mientes...el 2n3055 se lo debe utilizar y de hecho el voltage de operación máxima en la practica es de 50 volta...y usando de a par modo cuasi complementario o con mj2955 entrega un máximo de 180 watts ...wn 4 ohmios y 125 watts en 8 ohmios jamás 200w en 8 ohms ..para obtener 200w en 8 debes usar otro transistores como el mj15024 y subir el voltaje a 70 +/-voltios por rama

Hey

NOT EXACTLY...the other terminal for the speaker is actually collector current for 2n3055 which have lose to nothing negative(ground)

La batería es de 12v pero el amperaje de cuánto es

Kukira ponselku yang rusak😂

Hello bro.. Same here

These aren't functioning circuits. If you want to learn how to build amplifiers, for the sake of your time and sanity don't attempt these. The only amplifier in this video is the little Bluetooth one disguised as a battery.

If you love making amplifiers (as one who is 48 years old and been doing electronics since 6 years old and guitar since 14) i strongly suggest you learn some basic electronics and then you'll be able to make a real amplifier

Hi, i'm in electronics for my whole life and designing amplifiers since decades. Please, please do yourself a very big favor and don't spend your efforts, time, components and money in these "circuits" here which barely will work -in the best case. It's all just fake and lies. Building an amplifier which really works isn't rocket-science, but the circuit looks VERY different compared to that crap here. Try to get basic knowledge how a amplifier works. And if you see a amplifier circuit somewhere which you may find interesting please try to have in mind that the output transistor always have to be a complementary pair, consisting of npn and pnp. If this is not the case you should be very suspicious. Btw: the complementary pnp for the 2N3055 here is the MJ2955. Both of them are real "dinosaurs" in terms of transistors, cause they're since more than 50 years on the market. A pair of them is able to deliver something around 40...50W into a 4 ohm speaker -if you feed them with a supply voltage of about 50V.

🤣🤣🤣🤣

@@raffkuttaz That's what I just wanted to remark too.

Mantap👍🏻

Don't you know ?? By the bouncing nuts ! They indicate the shear power of this "ultra" amplifier. I am so underimpressed that I had to check my underwear for accidental discharge. The silence was also deafening.

Транзисторы включены паралельно, общий колектор, общий эмитер. Просто поделил нагрузку. И при чём тут эмитер к радиатору? Если на корпусе транзистора, колектор !?

Kagak lah kl tr jenis tersebut

Amperes de bateria 20A x 12v = ???

@@einarespada130 anche fossero 1000 ampere non cabia nada con 12 volt la sinusoide non distorce fino a 12 volt, oltre i 10 wat la sinusoide si appiattisce come un'onda quadra e produce solo distorsione, per ottenere 100 wat RMS occorro almeno 50 volt con una tensione duale -25 0 + 25 gli amper necessari per 100 wat a 50 volt che occorrono sono almeno 2,5 amper, oltre non servono, un cirquito elettrico o elettronico non in cortocirquito assorbe solo la correnre di cui necessita, anche se monti transistors o mosfet da 100 ampere a 12 volt tiri fuori sempre 10 wat effettivi al massimo. Con un suomo hf solo 8 wat.

Gli amplicatori delle auto di grande potenza al suo interno montano degli inverter che elevano la tensione fino a quello che serve per la potenza per cui l'amplificatore è progettato solo gli amplificatori in classe D ovvero digitali con 12 volt possono raggiungere potenze più elevate perche il segnale analogico viene generato a bassa potenza digitalizzato e riprodotto poi da un inverter che riprodoce la stessa sinusoide ma ad alta potenza. Un po per come avviene negli inverter ad onda sinusoidale dei pannelli solari all'interno non montano un trasformatore da 4 KW, ma ricostruiscono l'onda come per gli amplificatori digitali in classa D.

Sarà pure per questo che come attacca la musica sparisce l'audio del video

the ground is the base for 2n3055 and is brought to the black transistor by a resistor as a sort of feedback and not diret ground

hello

Hi 😁

xd

Yes 1000W. 1000 Ways tun on and off!

@@julianvalenti probalbly the transistors will blow up if its constant 1000w

@@Uraim imagine a low impedance U$$$$$$ 100w woofer receiving at least many amps of a dc power supply trough four shorted 2n3055 for some time!

@@julianvalenti imagine, you isn't smart, we have 12v rail voltage and 2ohm sets of speaker terminals, so the class A amplifier efficiency is 25-30%, lets see the best scenario, where the amp can produce 30%efficiency. So the output voltage will be 3.6V. (12V/100 then the 0.12 times the 30% it will be 3.6V. So lets calculate further. 3.6V on square and divided by the speaker inpedance. so it will be 6.48W at the best scenario. where is the performance that you trying to say?

@@Uraim if you want to understand it, look for the " viral side of published videos" and you will understand all this "magical properties kind of projects" like this and the 6000W generator made from a 150w fridge compressor and all the perpetual free energy generating machines that you will find. Like this 100W input power amplifier with 3W output power! Lets think a little bit more! Best reggards my friend!

Sir you did not spell AMPLIFIER correctly :P
