I see this in several of these build videos. You must have a good mechanical connection whenever you are attaching or connecting things together. Solder is to connect things electrically. It can get brittle and break with age, especially if things move around. It is work hardened very easily. What you see here might be good enough for testing an idea but anything permanent needs to be mechanically connected first, then soldered. And yes I am aware that modern machine placed components on circuit boards are often held in place by nothing but solder. Those work fine for tiny resisters and such that weigh nothing. Wiring and such needs good connections to last.
I am definitely going to build one of these, with a pre-assembled rectifier & pre-amp board though. I am amazed at how cheap most of these parts are, minus the toroid. EXTREMELY CURIOUS at how well this thing will sound on expensive speakers!!
That amplifier is so wrong, you need the VBE Multiplier transistor on the outputs heat sink or it will self destruct by thermal runaway, on top of that there is not fuse for the toroid primary, when the outputs get destructed the short will make that toroid a ball of fire.
Thats an awesome video, but I was waiting for the music test of 1000W or sinewave test to show 1000W, oh yeah. Its not there, can you make part 2? Or maybe I will make one.

50 watts, no more from that transformer. Dude, you need current! My transformer on my subwoofer amplifiers had 0.8 ohms as primary coil (1.5 mm diameter), secondary has 3 mm diameter 2x 45v. Yours looks for supplying... Something 6sq are the wires from the transformer to the bridge and the startup is done through a 30A relay So, what I see here is some amplifiers construction... But sorry, is out of discussions
Saludos compa veo que las placas son buenas y tienen 12 transistores por canal lo malo que veo yo es que tiene poco voltaje Pará los transistores y el puente rectificador es de poco amperios Pará mi tiene que ser de 35 AMP el el voltaje 75 minimo qué ya rectificado te viene dando 106v CD ojo en la red de 110v y el voltaje tiene que ser por canal
ala proxima conpañero descargue la corriente estatica, antes de agarrar un transistor por sus patas , sabe que al agarrarlo si no se ha descargado en un metal ,pone en corto el transistor saludos
What brand is the kit. + The name of the kit you used for this project sir.can you share it with me so I can build my own? Thank you so much if you do so.godbless
I am sorry but your transformer is quite small. Normally, if the supply is not fall during high consumption, 50x1.41 = 70.5 volts, means at a +/- 70.5 v, you can have around 500W at 4 ohms Better after finishing your job, insert a 1000hz signal at a 4 ohms rezistor and measure the voltage on it. P=U2/R...
Driver transistor doesn’t need to be big, they need to give less than 1A, so you used very good transistors where it wasn’t useful. Wires for power supply are too thin!
You risc your life working on non discharged capacitors. Please be a role model and be a bit more careful while showing the world how to work on line voltage. You might be skilled. Others might be killed...
I have two 500VA 50-0-50V torroids for my 350x350RMS amp and each torroid is bigger than the POS shown in this video! :D I'm also running 12 x 12,000uf filter caps, more than double the homebrand caps shown here. Must be one of dem PMPO 1KW for like 0.000001 of a second amps...

I really like your clips. Follow every clip. I'm from Thailand Knowledgeable I like electronics.

That is an important point, i see that too, lots of youtubers neglect that
Que maravillosa es la electrónica..más si la comparten y sus muchas maneras de adaptarse..gracias y muchas felicidadez

After this much hard work, video ended as if the creator was gonna miss the bus

Love the unedited soldering Going to build this one
Muy bueno eh aprendido de este proyecto, Jorge Quintana desde turbana bolivar

why do that entire build and then stop the video before testing and showing how good it works!
ពិតជាល្អណាស់ ប៉ុន្តែញុំមចង់ឲខាងនិង ធ្វើវីដេអូចាក់ផ្សាយអំពីថ្នាំសម្រើបស្រីនឹងរបស់របរទាក់ទៅនិងខាងសិចបន្ថែមពីនឹងទៀត សូមអរគុណ
the powersupply needs a centre tap from the transformer othervise it would not work well
Donde consigo esas placas para los transistores tendrás alguna página de internet donde se puedan comprar?
Saving this vid. Planning to follow your build guide.
Many thanks!!
te recomiendo que uses un transformador con tap central GND. que tenga 3 líneas de salida .
this is a VERY serious realisation ! congratulations !!!
Jitna aapne is video me bnaya hai sab chizo k sath courier se chahiye price btaye

Thank u for gd work but please I want audio explanation
1kw from that 400VA transformer?? haha good one,cut a 0 from that 1000W !!
good idea thanks you very much
Good job brother👍👍

Nice assemble..
Ce cool vraiment j'aime
Not1000watt
Transformer 55vac × 1.414 =77vdc = 224watt@8ohm
Wire section on those 10000mF : too small
Same as the Behringer EP4000 PA Amp.
Nice love this channel
Good day po sir! Ask ko lang kung magkano inabot ng power amp. Hindi kasama ang speaker, salamat po sir! Good job.
ভাই 12 টেনডেসটার সার্কিট এর এমপ্লিফায়ার কিভাবে বানায় তা নিয়ে একটি ভিডিও বানান
Good sir
ala proxima conpañero descargue la corriente estatica, antes de agarrar un transistor por sus patas , sabe que al agarrarlo si no se ha descargado en un metal ,pone en corto el transistor saludos
Y donde se consiguen las placas y todo para armarlo o si ya se puede conseguir ya armado o todo el material conpleto
What brand is the kit. + The name of the kit you used for this project sir.can you share it with me so I can build my own? Thank you so much if you do so.godbless
i think its only deliver 150 watts and not 1000 watts because the torroid you use are very small
Wow its amazing only 55 0 55 supply make it 1k wts it's impossible lol
How much ohms are like many power amplifiers are 2,4,8 ohm ??
Cool amplifier board duild my friend, is it a class A amp? 😀👍
Super excellent bhai jawab do den na aapi reply Deven Kemon thank you
there are so many misconceptions in that assembly.
I would never want an amply like this!
Hi how much ampere we need.
😊please reply me.😊😊
Nice
A short circuit protection shoud be included, once a power transistor failed, the amp will be totally killed. No fuse ever does.
nice videos

P=U2/R...
How about how many volts that power supply? Thanks hope to your response.
upto 70+70 V DC
Very nice bro
Cuanto sale el presupuesto de todo eso para ese amplificador
Sir mujhe bhi shikhna h ye sab,,,,,Kya aap mujhe shikha sakte h.........

You are changing the pre drive trans to same value as the output trans.. 1943 and 5200..
Thank you for reply regards..

what? are u using full wave? i think u should use dual complementary power supply.
supère je vous félicite
mery pass chota audio system hai jis me 8inch ka eik 6 inch k 3 speaker hain. awaz ziada krain to phatny lagti ha koi circut bata dain mehrbani

Sir...why you are connecting ground with AC !! Pls say sir
Yes. I think he want to blow circuit
Can you also show us when it exploded? :-)

can i ask if how much would it cost when you sell that? i would appreciate your response
Brother make 24 v SMPS to dual supply
Nice god👍👍👍👍❤❤❤

Sir 10 2sc5200 ke pair wale board me kitne watts ka transform lage ga
note : it is not a diode, this is a bridge
ভাই আমার ট্রাসফারর্মা ৪০ ভোল্ট ১২ নাম্বার ডিসি তার আমি কত ট্রানজিস্টর দিতে পারবো এবং কোন স্পিকার লাগাতে পারবো।
hello can someone tell me where I can buy the material to make the toroidal transformer core, thanks
The transformer is no CT ( center tap ), can you draw the conection to bridge dioda and caps ?
Nice board sir...
Sir 15inch 300w 8ohm 2speaker ek board se chalega?
How mach cost amplifier
High Watt amplifier me chota sa speaker .... matlab amplifier me dum nahi hai.... make amplifier like... our Ahuja Amplifiers
Sir es poroject ka total kharch kitna h.ore one chanel modul ka kitna kharch h.
NO TIENE LOGICA LA FUENTE DE ALIMENTACION EL TOROIDAL DEBE TENER 3 HILOS Y EN EL VIDEO SOLO APARECEN 2!!!!! A VER A QUIEN ENGAÑAN!!!
Ground..........!!!
Hi do you have any idea,how much wattage this power amplifier,it has 80vac and 10pairs of power transistors?
Maaf boos .kalo 1000 wat travo sama diodanya kurang besar .sama jamper elko nya di pararel pake kabel 1 mm
Anyone liking the muisc more?🥳🥳
Not a diode, it's bridge rectifier
Pano po bumili ng pyesa nyan lahat po at saan po
awesome 👍
Which transformer do u use sir
excelente ! ¿tienen los pdf para compartir? saludos amigos.
Chispas nunco te respondió este Amigó
How much cost of this board?
Hii
Excellent 🍊🍊👍👌
