*DIY Powerful Ultra Bass Amplifier TDA7388 BTL 12 Transistor D718 , No IC , Simple Circuit **kzfaq.info/get/bejne/Y71hlpthqNvTYZc.html*

7000W LOL. The so called power supply polarity changed between 8.47 and 8.58 and back again during the "demo". Capton tape does nothing as the transistors are screwed directly to the heatsink. Capton tape around the battery casing. My suspicion is there is a bluetooth module, small amp and battery inside the larger battery housing. the audio is fed virtually direct to the speakers via those heavy copper wires. The FET's do nothing. Love these vids. So much fun working out how it doesn't work.

Пойду на своём сабе напишу 2000ват, и тоже видео сниму xD

Just a few concerns: First off, even though you used Kapton tape to insulate the low side transistors, the transistor drains are still connected to the heat sink, via the screw heads and threads. Second, both the input and output capacitors are reverse polarized. (both hooked up backward) Third, I don't see any pull up current to turn on the high side MOSFET's. The 270 Ohm resistor connected to the base of the D718 transistor is going to pull the gates of the high side MOSFET's down hard, regardless of input signal. The collector of the D718, will just pull the low side transistor gates to ground, turning them off as well. The emitter-base junction voltage drop is only ~.6 volts. It's just like a diode, with the cathode connected to ground, the anode connected to the 270 Ohm resistor. These are enhancement mode N-channel MOSFET's, so, to fully turn on the high side transistors, you need some kind of bootstrap circuit, to drive the gates at least 5 volts(a bootstrap circuit would give you 6 volts, if you are using a 12 volt battery) above the positive rail. I'm not seeing any kind of auxiliary supply, or, capacitors to shuttle the voltage from the output to the high side gates, to turn on those high side transistors.

This is low-fi. You need a high pressure vacuum tube push-push stage to drive your output stage. Think bipolar speakers, Mirage, Eclipse BP etc. Also, no transistors from broken ebikes and personal massage units Get some lateral FETs, Black Gates, Serpentis Oleum for smooth moving coil coupling. Just use a normal MMC thats tuned to the exact eigen takt of your room or house. This way its self exited and this provides very high ritalin effect in the standing WAveguide for Negative Koeffisient Erroneous Refractivity. If mmWave = active, goto "RattleLube". What cable did you use to transfer music or power? This must be audiophile quality or bit-perfect is no longer 1s and 0s, but maybe 0.98s and 0.3s. Its common knowledge that a computer must have 0 and 1 for binary refinement state. Integers and floating point is different, and the difference is called delta. For temp is deltaT and for bits in binary code its delta-integerale. This is the push-push with no compression loss. Force instead of lossy compression. Übermacht immer gewinnt. The most important factor is the wifi and the ethernet its connected to. Only 10/100baseT with solid aggregate state and Alligator Arresters. NO UPS. Uninterruptable PSU needs to be 50% interruptible to allow proper function of interrupt requests (IRQ) in the asynchronous audio transmission. Rifa, ROE, Elna etc does not work in PSU. Only reverse biased tantalum stacks. Hundreds of uF with reversed bias stacked tantalums not only sounds great, but all those orange caps soldered nicely together looks awesome. Better than High-End is Sky-End.

12V 12Ah battery?? max 10watt amplifier

Muy bueno! pero tendría que ponerlo al Woofer en una caja para poder Apreciarse bien el sonido

A lo mucho 5w, todos los transistores en paralelo jajaja, no tendrás potencia con esa configuración, si fueran 7000w el altavoz se estaría moviendo con más fuerza y se ve que apenas apenas le da para mover sos altavoces

Mantap bro ok ni 👍👍👍👍❤️

muito bom parabéns, falando do Brasil goias caldas novas.

watching and sending support again nice sharing

Kelebihan MOSFET mampu menghasilkan power daya Watt yg besar,seperti mana banyak kita lihat pada power amplifier kereta dengan Suply 12 vol mampu mengeluarkan bunyi yg menggerunkan .. mungkin jadi kajian dan sebagai inspirasi kita semua untuk mencoba sendiri di rumah .. selamat mencoba dan semoga sukses 🙏🙏🙏

Это же какая входная ёмкость затвора этой гирлянды

Very good...

Wow 🤩🤩😍😍🤩🤩🤩

Muy creativo pero le pregunto cual es la corriente adecuada para el funcionamiento correcto del mismo gracias si no eres egoista epero tu repuesta felicitaciobes

You can put thousands of transistor but if you didn't increase the dc input you can't go anywhere. I'm just learning but watts or ohm means or is almost equivalent to input voltage

Wow keren.😀

2к и 3к динамики нельзя запитать от 12v акума бо не хватит мощности им как минимум нужно 220v плюс наушники так нельзя подключить не будет работать и да эти динамики один на 200w другой 150w это примерно

Genial muito bom (10)

Saludos hermano que tipos usas para este circuito

superb I have to try it

❤❤❤

good job, but if you could put the loudspeaker in the box, I would like to hear the bass because this is how you can only hear the music is going and the bass is 0, it will be completely different in the boxes

👍👍

👏👏👏👏👏👍🏻👍🏻

Qual a corrente adequada pra se colocar nesse amplificador? Em corrente continua. 🤝 Ceará- Brasil

Los que aislo necesita aisladores de plastico en los torniosso los negativos ya que reciben corriente negativa

Gostaria de fazer .

Heyy bro Can you make a easy one please

what is the limit power (A.C) for it i want ti use volte instead of battery

Все это ерунда, по факту усилитель на одном транзисторе D718, мощности здесь не больше 10 Вт

Puoi anche montare 8000 transistor, ma se li alimenti a 12 volt, ottereai al masdimo 10 watt RMS.

Wow

Good video

Woww 99999 bastt🤯🤯🤯mega bastt

mạch loa công suất 👍👍👏🏳️‍🌈

Hay quá anh đức black

Nice bro👍👍👍👍👍👍👍👍🌹

Good

se puede conectar corneas de 8 ohm a ese tipo de planta casera

12V @4ohm =3A the maximum output power il 36W

what is the song name which you play in speaker at last

wait a moment! why you use this yellow tape? as an isolator? really? do not think so, the Drains go to touch the heatsink anyway! just because the screws have no isolation and connect both surfaces! nice try! hehehe and almost forget it...finally you decided where to connect the battery red cable!

Nice 👍👍👍

Dude, without mixing amplifier, tune's like normal range speaker

Nice

Alektronik firmaları hiçbir şey bilmiyorlar bundan akıl alsınlar 😝😝😝😝

जय माता दी

Круто

good job sir, watching sending my support

A dùng thiếc j vậy

Лайк за видео, ты молодец 👍

Gücü çok az olmuş? Hoparlör diyaframı neredeyse hiç oynamıyor. Performansı düşük gibi.

Kkkkk,48 MOSFETs R$> cada um custa 20 a 30 reais se tá louco. , Fica mais caro do que comprar um amplificador completo. Kkkkk , só tem louco nesse KZfaq. É cada uma

🎉🎉🎉

Изолирующюю прокладку поставил, а винты не изолировал....

Xem đầu

Si no colocó los aislantes en los tornillos, creo que nos está tomando de bobos, porque al colocarle la alimentacion se juntan el negativo con el positivo y todo se arde. No creo que sirva de algo esto.

Put your speakers in enclosures

hey you try build same this circuit..but u just used 1 pair mosfet..i think the sound its same...

Wow 48 power mosfets Q, Why WTF 4???

Огонь, изоляция каптоном, а винты без проставок. Фейк, кто то ведётся.

Bruh that’s a huge waste of mosfets, I would use those mosfets for an inverse circuit and it can probably transform huge amounts of energy

Bro video m thoda Bola Karo Components ki jankaeri Diya karo

Never ever connect left and right channel straight together. Frequencies could cancel each other and in worst case, you could blow the output stage of youre soind source

where is the thermal paste

43 mosfet do you think all are working?

Purchase links please

50w amp+10a acu=50w sound 1000w amp+10a acu =50 w sound

Bom

Less voltage brother

necesito el esquema por favor

Hâha người Việt

Sao giống anh thợ điện ấy nhờ

How many watts will this circuit give

U wil not assemble HPF & LPF bord with this amplifer 👍

Nice bro👍👍👍👍👍

hola quetal me puedes Aser uno Soy de Olimpo

There are so much problems, for mosfets the tape is okay but the screws dont have voltage protective plastic on it, its gonna make instant short circuit you not gonna run an amplifier on 12volts while there are 48transistors, waste of material and time.

Ser gd am ask kulang kung magkanu mag pa assemble nyan muspit ang gamit

Из какой страны ты

Trên kênh anh thợ điện ko thấy phát

yo kiero uno de esos

Que mal q use una batería eso hace q no desarrolle suficiente potencia

Well ok that's one part of an amp now you do no that all amp work off ac so now you need to build the power supply for what you have there and then you can wake it up

Nagyon torzíthat.

como se hace uno haci para saber armar uno

Good 👍

Ay kayfullah wruplar korpus veeie oduki camati xerce salma bic

12 вольт мало, надо хотя бы 24

No mueve nada los conos.. le falta mínimo 70 voltios

It's 0.5watt rms

Legal. Mais esses falantes de 300 rms. E vc falar q é de 3000 E foda vei

Bisa di pesan ngak mosfet 75n75 nya mas

Какой смысл подключать низкочастотные динамики в полную полосу?

Ser hou much assemble

7000 watts woth 12V ? , It means that the cables Can support like 550 Amps of current , its too huge for your battery. At the maximum the current is around 20Amps ... 240W ...LOL

El transformador es el secreto con 12 voltios no moves una mierda

I don't think this is more than 400watts RMS
