My handmade power amplifier project 1000W

[StavrosCustom]

Is just power with no quality so...

[jh78ghbn56]

Intersting looking amp my freind. I would like to know the transformer specs, what rating capacitors you had and how many, what transistor you used, and how high was the current you draw, Im guessing it must be north of 30Amps seeing those thick wires, and what load speakers you had,8 ,4 or 2 Ohm. Thanks ^.P

[DONDIVA1969]

Haters gonna hate.

[crackhead97full]

@toniemi85's SPeeCH

[crackhead97full]

that's true but i am 14 years old and when i was 4 i fixed my first TV

now i am making a 1200w (60v 20a)power supply and a class A 300w amp (0.0005% distortion)

SORRY FOR MY ENGLISH

[MikiElectronic]

This is not your amp, you bought it! -.-

[chrisrole1]

this is not design by an engineer but only a hobbiest!!!!!!! hah hah hah..

peace,,kawawa ka naman

[jh78ghbn56]

that is quite the heatsink yourve got there ^.^

[glennoyke]

.... im trying to make one to and ittl give the same effect but its gonna be about 5 times smaller so why the crackanut so big?

[palka06]

нету тут киловата! ! ! хотябы дажепотомучто транс на 250-30 ват!

[45llamas]

DE DONDE SACASTE EL ESQUEMA? ME LO PODRIAS DAR ESTA MUY BUENO TU AMPLIFICADOR !

[45llamas]

schemathics plisss i from chile i'm like your amplifier

[sanosukke]

@45llamas yup, you're just like it.

LOL, sorry, just couldn't let it slide.

Anyway,

@toniemi85

really good looking amp, but how does it sound? Is it inverting or non-inverting? And how's the distortion? Any clipping?

[antispammaster]

Dude if this is your build can you send me the schemathics by DM?

[JubiTheVille]

@everyone, all you need is a computer. instructional videos, forums, diagrams ect... case closed. like a calculator to math, a computer to knowledge.

[bassmekanik101]

And turn it on so we can see and hear how it works

[6527mjap]

I think it's a kit, if it was hand made it will be so messy. i made simple amplifiers too, kits, and built by scratch but with a schematic diagram for instruction. transistor, IC, mosfet. but one thing I wanted to learn is to build a tube type amplifier.

I wish I had money that time to get better education. ^.^

[pr4wn5tar]

so does it make noise?

[hacker8081]

play it

[fvang199]

thats two big ass capacitor inside for amp...

[z3r0zx1]

And you couldnt just buy a real amplifier?

[thegr81337]

hmm sorry to see it go

[jigibao]

I SEE 20transistors "push-pull" there and that is rated at 1000watt rms.. BUT i have problem with your power suply,remember for 1000watt output you need at least 1500-2000watt power suply...no food "electrycity" no power!! nice done...

[heff44x]

who gives a shit about what it puts out just the thought of making an amp is bad ass

[kuza261]

lol like 10 watts

[MrEinstain]

pretty damn good.Test video?

[taborsio1]

do you have a diagram of this?

[SoumyaSumitra]

Hey dude, i have a 4 ohms and 30 W Woofer speaker. How to build a amplifier for this to make a sub woofer of 5.1

[royalbrainwave]

get the fuck out of here with that shit video, RETARD!

[vitorix24]

WTF

two BIG bobins xD

[maciejwrotek]

full power full system, now they will experience full power of the dark side, do they not ?

[fast85e]

There are plenty of people that will make you a custom transformer too. Not a bid deal at all. Most high power RF amps need to have custom transformers made every time. Custom stuff is only as hard as you make it. You can even blow your own custom vacuum tubes if you want....

[fast85e]

Wow, you guys don't know anything on here. Just search "prototype PCB" in google and more then 20 companies are out there that will make you low quantity boards. I've had boards made for over 50 projects now. Pad2Pad even has there own easy to use design software. Before you post like you know anything about anything, do some research!!!

[sparky3489]

Umm yeah, a "prototype PCB" from a company isn't exactly hand made now is it?

Before you post again, try not to get athletes tongue.

[sparky3489]

Where'd you buy the kit from?

[sweffe96]

Doubt its a kit ;O

[sparky3489]

Just one look at he PC board and it's CLEARLY a kit. I know, I make my own boards.

[sweffe96]

Right....

[sparky3489]

Yup, just check out my vids or the link I sent you. I've been making my own boards since 1986.

[sparky3489]

Oh, SNAP!

[sparky3489]

Umm, no. A PC board is usually fiberglass layers glued together with traces between the layers for multi-layered boards solid copper clad for single/dual layer. I etch boards which means I make a Printed Circuit board.

Nothing is "hand made" in the video. ALL the parts are just hand assembled. BIG difference. If he'd hand wound the x-formers, there'd be no arguement.

Go to 0:35 in the video, the boards are colored which means they came pre-made from a factory ergo a kit!!!!

[MartyHITD]

Now see, theres a arguement. A man who knows his stuff. About time someone managed to argue a good point back. Sorry for wasting your time, just had to see if you were general or a tard. I'll remove me comments. Very well done

[bob505470]

actualy the board looks like a peice of ebonite rather than a fiberglass pc board. he may be using it to just hold the parts in place. ive done that mayself a few times.

[sparky3489]

Where are you looking? I'm looking at the red and yellow board with the huge heatsink down the center and caps on the end of the heat sink.

[bob505470]

same place you are, the board is not eched

[sparky3489]

It certainly isn't wire wrapped!! I never said the board was etched but it has traces like an etched board.

I know all there is to know about boards as I'm an IPC-7711/IPC-7721 certified specialist in board repair as well as a certified J-STD-001D specialist in Requirements for Soldered Electrical and Electronic Assemblies.

There's nothing you can tell me I don't already know.

[3yE]

@sparky3489 mind you, the board looks like single sided, otherwise one would faintly see traces under the laquer on component side. You can also etch your board, spray paint the component side then drill before assembly, which would give exactly that look on a self-etched board. The solder/trace side is obviously bottom.

Of course without proper project docs or specific kit name one could argue to death and still be wrong. :D Where'd you see a kit with such a corner radius anyway?

[sparky3489]

What does being single/double sided have to do with anything?

Why would you paint something that most likely wouldn't be seen when the REAL spotlight should be on what it does?

You can buy kits of all kinds of all shapes and sizes depending on the kit.

[florickwar2]

get some real speakers whit a 98db+ efficiency and a power amp whit a 10killogram aluminium heatsink holding twenty to-3 style transistors and a block transformer capable of 1500 watts and a capacitor bank beond your imagination .  ,and dont talk about crown and qsc their products are rubish to mutch plastic and no transformers and in case your plx dies u will have to get spare parts costing half the amps worth - where did the real oldskool amps go ??

[M50SNIPER]

LOL capacitor bank..pSSHT

[terraxtxx]

great job

i think the heatsink is too small for 1k W

it's a dyi and it's great keep it up

PS : for the unknowing search speaker sensitivity and spl vs power instals

cheers

[adam10603]

1000W ... LOL ... have you ever heard even 100W ? that blows your head off. 1000W may destroy your house. You are dumb. Im sure thats not 1000W. I know, very huge wattages are written on car audio things, but those arent true. Listen to a 100W guitar amplifier stack by standing infront of it. Im sure that a 100W marshall stack will push you back off your legs. 1000W ... DUDE!!! you cant even imagine what does 1000W mean.

[peerless77]

The loudness depends on the sensitivity of the speaker, not the amp power.

Have you ever heard of the Crown IT8000 PA amp. 8000W bridged into 8 ohms.

1000W amp would be 10dB louder than a 100W amp, which is about twice as loud.

[chrisbx1975x]

you correct about how loud it will be. especially if it is a two channel and it is a real rating. if it's really 1000w he most likely is not using it for guitar. guitar speakers are much more efficient than normal speakers which is why 100w with guitar blows your ears off. it does all depend on the size room and your physical distance from the speaker which both also directly relate to the spl you will have to withstand.

[deckoland]

you don't know jack, its obviously for a subwoofer and a subwoofer requires a lot of precise power for excursion the coils in a subwoofer are much thicker than those found in high mid range speakers high mid range speakers require less power becuase the coils are thicker theres more resistance and transmition is lost through the magnet

[maddfix]

r u retarded? u've only typed rubbish....

[deckoland]

no you are becuase you don't under stand it

[JEAG]

Dude... You got no idea... I've seen some 4000W speakers... OMFG they sound GRAND!!! I have a Peavy 120W Amp but those SP2 speakers hooked up to something 1000W is fucking insane... Can't destroy your house... I tried it... Didn't work...

[MagicalMrSkylar]

ACTUAL car audio things do more than they say. take the sundown audio saz 3000 which can do 4000 rms. read a book noob.

[B0DYR0T]

You're an idiot, watts have nothing to do with loudness...

[adam10603]

i know, volume is in DBs, but anyway, 1000W is too much power for an amp like this. lol. if you plug 1000W into something, then ur house blows up :D

[B0DYR0T]

Why, watts are just a measurement of power... You could use a car audio driver and get the same loudness from 1000 watts as a 100 watt driver...

[M50SNIPER]

Depends on the frequency of the "loudness" along with other factors. Yes it is possible but it would be a higher frequency and no SPL.

[M50SNIPER]

I know nothing yet I get paid to do this work for over 3 years? You don't even have good grammar. Are you in 3rd grade young pubiscent child?

[M50SNIPER]

Your dumb as shit. Watts are the amount of heat you stupid shit. Go kill yourself and stop posting bs.

[M50SNIPER]

BIG ASS HEATSINK. How come at a 120w RMS speaker running at 160w rms gets hot? Its still 4 ohms of resistance. But when I plug it into a 100w amp it doesnt get hot? Also resistors are measured in not only ohms but also in watts. Watts meaning heat dissapation. I get paid to do this shit. Learn proper grammar before you type stuff and argue with people, even though you fail to give the whole and correct answer.

[B0DYR0T]

My bad dude friend got on my account to talk shit to someone, and he thought it was you (Comment received at the completely wrong time). My bad dude, yeah I know you're right. He was looking for this Darkeyce02 douche bag... anyway my bad, wrong person.

[M50SNIPER]

Oh ok bro. No problem.

[B0DYR0T]

Just wondering, isn't saying watts is a measurement of heat wrong, in the sense that the heat produced is the watts wasted, meaning like the more efficient a circuit is the more watts truly utilized and less heat will be produced? Just curious now as to what if watts and heat really go hand in hand, or is it just the resistance or poor circuitry . Anyway I'll send you a friend request so we don't spam this video LOL.

[wcocowcocow]

@M50SNIPER actually your both sort of right because watts is a measurement of energy and they are both energy.

[HobieTyourtube]

Nice Job--------------BUT!-switch mode power supplies--rock?

Heavy Thermal heat sinks mean--------your Amps are---inefficient?

I guess the exercise is-----------tranfer the mximum energy to the speakers?

Steve,

[fireicer]

yea i see allot of new mosfet amps coming out with switch mode psu in them. personally i think toroidal transformers give the best power for mosfet amps, thats just my personal opinion mind. my last project which i may put up on youtube was using a sanken mosfet with a balanced thermistor built into the transistor to compensate for the transient yet they dont like handling very very high power like this

[dividebyN]

Nice1 for a bit of homebrew kit, Is it bridged for 1K mono? 20-40 % will go in heat, but if it's bridged. . . prob nearer 1.5-2K ! Depends on u'r mosfets and supply voltage/ current. . . 5 *'s 2 U !!!!

[RDSvSRockfordFosgate]

wow...clean work....is that a car amplifier or home amp????

[fatharmonix]

how many output transistors?

[johnziebass]

i think it has 20 output transistors

[barevids]

shit man look at them caps

[fatharmonix]

not that amazing if u ask me, at least compared to a vintaege tube amp.

[billkab]

You could that in the auto body repair field as a welder, lol

[TheLightningStalker]

Nice work. It looks much better than the stuff I build. Check out my site: hxxp://kickme,to/lightningstal­ker

[bitrex]

That's some big iron thar

[nextlifeguitarist]

nice...i use to design amplifiers too..my last creation is a 250+250w/8 using 2sc3264/2sa1295 from sanken, i am trying to use some ideas coming to integrated electronics like to put three differential amplifiers in parallell for the voltage amplifiier stage input using 2sc3381/2sa1349 double transistor from toshiba just reduce the noise and, i hope, to reduce the IMD.

On the next i will use current feedback, i never do that before, it could have much better slew rate than a voltage fbk

[T3RM1NH4CK3R]

OMG , make turtorial how to make that.

Thats Awsome ! i really need to know how to do that :)

( i Rated 5 Star Video )

[ukyouchrono]

What materials are you going to use to make a simple amplifier? This is just for my homework in Electronics. Please tell me the materials

[uN1Qu3DZ]

That's a nice PCB. But you DO need a bigger power supply. I did the same mistake myself quite a few times, and wondered why the amp distorted a lot earlier than i expected it to. When i plugged the meter in and saw the voltage drop on that poor power supply i understood.

First step in any good electronics project is a BIG power supply. In your case you should go for a toroidal transformer, it's more effective and delivers cleaner power, although it is more expensive it is worth the price.

[toniemi85]

I was 16 year old when i designed and calculated and build four different audio amplifier and many other aplication one is this. This is not my graduation project.. I win 18 year old bronze Taitaja 2004 FinnSkills -competition, but i don't was engineering..

[KlevenRobert]

Your powersupply will short out long before it reaches 200 watt on 8 ohm, let alone any lower. This is an obvious example of trying to make lots of power out of cheap parts. Not gonna work... For example, your capacitance is WAY to low, a 400 watt @ 4 ohm amp uses 100000 uF capacitors on each sinushalf. The transformer looks like an old hifi trans from 1980. + 60v - 5v decay gives you no more then about 100 watt @ 4 ohm. I tought this would be interesting... Go learn instead of copying...

[toniemi85]

:D You are envious! What you have done you hands?

[KlevenRobert]

You don't know propper english? Let me translate noob

You are jealous, what have you build yourself?

Let me answer that...

I have designed, calculated and built a 100 watt 4 ohm rms amplifier with +40 0 -40 8A total regulated powersupply as my graduation project.

[toniemi85]

1000W Amplifier is project name, not realy rms power. but measure power is if i remember 250W 4Ohm * 2,becouse my amlifier working almost a-clas.. input means power is 1400W/230VAC

[KlevenRobert]

I don't care about your output, the output could be way over 5000 watt with those mosfets if it were a class D amplifier. Whatever class your amp is, your powersupply can NEVER handle more then 300 watt.

[toniemi85]

yes, 300watt is perhaps real handle power, but peak power is more.. i don't build a-clas amp, but this sleepcurrent is big. 300W is many watt.

[KlevenRobert]

i said, your powersupply can't handle 300 watts of power, that means when your amplifier is in class A, it won't deliver more than 100 watts on mono

[toniemi85]

100W is lot of sound and it is enought, but my powersupply can hadle 1000W, if can use. i don't realy undestand what you say, sorry.

[KlevenRobert]

The fact you don't understand what i mean is because you don't know enough about amplifiers to measure output power and your video is overrated...

[toniemi85]

i don't undestand english very good.. video is overrated, yes! but I was 16 year old when i designed this!

[criticallistenphile]

@toniemi85 Very nice work. Thank you for posting your video. Who cares what the hypercritics have to say. It's easy to complain from behind a keyboard. Keep it up. I like it.

[BKKTran]

@toniemi85

You designed this when you were 16? That means studied calculus and physics at the age of 10, got into a university at the age of 12, and graduate with a bachelor degree in electrical engineering at 16.

And i'm fucking Iron Man!!

I'm an electrical engineer bro, you can't bullshit a bullshitter

[razorrick1293]

@BKKTran you dont need a degree in electrical engineering to build an amp.

[BKKTran]

@razorrick1293 Yes, any moron can download a schematic and build one with some instructions and basic electrical theory. To DESIGN an amplifier requires an in depth knowledge of electricity and magnetism, as well as a profound understanding of analog & digital circuitry analysis.

Yeah, you don't need a degree, but you do need at least 3 years of engineering instruction before you even know where to start. I highly doubt a 16 year old would have such knowledge to design an amp from scratch.

[razorrick1293]

@BKKTran that depends on what your going for, something simple, like a few op amps and a decent power chip isnt hard to design, ive had a pretty good go at valves and been quite successful and im 16 (this is after the 12v project i have uploaded which failed a bit). but something high powered like this i agree would take some knowledge

[TheKaos90]

@BKKTran Looks like a production amplifier to me ... no handmade or whatever

[TheInuyashaDogDemon]

@BKKTran anyone can do anything, they dont have to have a degree! Fuck degrees, their retarded! and so are you

[LauxHawk]

@BKKTran I'm 16 bro, and if you spend enough time on anything you can do this. I started learned electronics when I was 13 and I can hold a conversation with a electrical engineer no problem.

[MrStemkilla]

@BKKTran dude settle down i do complicated shit like this too and im 15 ive literally went from simple knowledge to something close to this level in one year without the classes.. when your interested in a component you lern about it then after a whale you can put the components together and do way more complicated things

[poodlelord]

@BKKTran Actiually, a senior at my highschool built one of these as a side project.

[cj691]

@BKKTran A piece of paper does not make or break someone from being capable of things.

[narcoti]

@BKKTran You don't have to have a fucking bachelor's degree to fucking design this, an audio amplifier is child's play, you don't need to know calculus either. Oh and by the way, have fun wiring houses, this is electronics engineering not electrical engineering BIG difference between the two, now fuck off.

[nMAPPER]

@BKKTran

You need to know surprisingly little mathematics and electronics to design a power amp. A properly motivated 16year old has had all the needed math at school and can then go to the library to study up on the needed books. I could have designed one after my first year at uni, and probably earlier if I had the drive to do so. So it is perfectly possible. Hell I know a guy who can do this, he designed a 6meters linear amp at the tender age of 17.

[fingerboy18]

@BKKTran If he was such a good engineer, he'd know not to put electrolytic caps so close to a heatsink. That's a no-no.

[cassius969]

@fingerboy18 But then it might last a long time and never break and people buy less new stuff. Open up an amp, for some reason they put the caps NEXT to the heatsource. At least they did in my old Kenwood, which is why they are all fcked up and I had to replace them. And that thig generates a lot of heat too, while putting out only about 65 watts. Made in the late 70s.

[pero2727]

@BKKTran actually; in some countries like mine (Slovenia) you are given an assignment like designing and building an amp like this in highschool. You are normally give 2 months to complete it. The assignments at university are more like design of microchips and such (I'm only second year of university now, but we had to design simple chips allready... your country's education standards just seem a bit lax.. ;) )

[Henzzman]

@KlevenRobert I wouldnt be so sure about the incapability of the transformer.It looks its very heavy duty style and the core seems to be quite thick,so i think the transformer could be in the 1kW+ range.

[machturnip]

@KlevenRobert You, while criticizing someone's english, spelled the word proper, improperly. Before you say "That was just a typo!", let me point out that you also joined two independent clauses with a comma, but did not include the required coordinating conjunction, nor did you use the more appropriate, in this case, semicolon. In the same sentence, you also used the wrong tense of the verb, build.

None of this matters, but is just a way of giving you an example of assholery. Dont be an ass.

[KlevenRobert]

@machturnip i can speak english dutch french and german, how about you?

[thegr81337]

@KlevenRobert yeah, that google translate is wonderful, isnt it ;)

[KlevenRobert]

@thegr81337 lol?? you can do better then that i hope... worst oneliner i've ever seen

[thegr81337]

@KlevenRobert ok, i was trying to lighten the situation, but you can be a duche, thats cool too

[KlevenRobert]

@thegr81337 what situation?

[thegr81337]

@KlevenRobert the situation of you bashing everyones comments

[KlevenRobert]

@thegr81337 seems like no situation to me :P dramaqueen

[thegr81337]

@KlevenRobert thats drama king to you!

[KlevenRobert]

@thegr81337 that makes you the one s*cking my c*ck

[thegr81337]

@KlevenRobert so be it, but dont write checks that your c*ck cant cash

[KlevenRobert]

@thegr81337 this conversation is CLOSED due to failure and boredom

[thegr81337]

@KlevenRobert hmm, sorry to see it go...

[machturnip]

@thegr81337 Actually, that was the best one liner ever. I checked with Guinness.

[machturnip]

@KlevenRobert For the sake of perpetuating this amusing back-and-forth, I will claim (lie) to speak Swahili, Twi, Cantonese, Aramaic and Pig Latin. (I can order appetizers in French)

Actually, I only speak English, because I think that being good at one thing is better than doing one thing poorly, and then pretending to be able to do a bunch of other things to make up for it.

[thegr81337]

@machturnip agreed

[brycewoot]

@machturnip yay for trolling!

[maynardr6]

@machturnip zomg, if you had vids, I'd sub.

[topgun182]

@machturnip kudint sed it beter miself. and I meen dat.

[1999eking]

@machturnip who gives a shit about propers grammar its the fucking internet!!!!

[machturnip]

@1999eking Did you read my whole comment? It had nothing to do with grammar, except that I used grammar as a metaphore to illustrate that other dude's obsession with forcing his opinions on other people. It's called satire. Wikipedia that shit, it's fucking awesome!

[26xl888]

@machturnip I think you will find it's 'ass-holery'

[gautlet996]

@machturnip well said my friend, well said.

[shredmaster999]

wish you could share the schematic

[daz2084]

That looks great! Looks like you put great effort into building this. shame we couldnt see it working though.

[albundy316]

Very good amplifier! Just one question: how much is the capacity of capacitors? Thx anticipatory... :)

[toniemi85]

4*47000uF + 2*22000uF..

[albundy316]

thanks

[WEWETPUWET]

hey!!!go back to school and learn!!!

[kskate91]

what ohm load can it handle?

[toniemi85]

4Ohm but maybe 2Ohm

[mavallarino]

does it get hot?

[toniemi85]

yes.

[aurelrica]

is this build with mosfets or bipolar transistors

[toniemi85]

2chanel * (5*2NJ162 & 5*2N1058) = 20 mosfets

[WEWETPUWET]

ei!!!!!!!!!what is the supply voltage of ur circuit

[toniemi85]

+-60VDC and 1,4kw

[ivansdco]

that will be a monster
