Thank you for watching the video. please support me. Thanks you very much. love everyone.
Disassembled, washed, painted, poked random contacts with a tester, assembled and everything works. Brilliant! Wonderful!
Not to mention, set bias and DC offset using mental telepathy.

كانه مصنوع في ١٩٧٥
Okay yeah, more of a deep clean than a renovation. The amp obviously worked before the strip down.. However still a good watch and definitely better than watching some crap soap with the wife ! 😂
yeah forget all the other stuff he did like pulling all the caps and testing everything for continuity and testing all of the caps to make sure they are good. sometimes a good clean can make things work again so instead of being so damn negative keep it to yourself. "poked random contact with a tester" tells me that you have no idea what you are talking about too.
It made my heart feel so good to see cleaning completed BEFORE repairs were started. I watch hundreds of vids which don't even give a minor dusting before new parts are installed. I cant understand why any tech would start before cleaning. After my service ended in the early seventies I entered industrial maintenance work with some really top notch professionals who insisted on clean first which I maintained my whole 42 year career as an industrial electrician working in rubber, foundry, trucking and auto dealerships.
It doesn't look "well cleaned" prior of dismantling (still a lot of dust)
A +++ for repairing location ,garden air blower rather than air compressor and technician slippers.... oh my god :(((
Pesawat amplifier tersebut tampak sehabis kebanjiran air dan sampai mengering kembali syukur setelah dibersihkan dan diperbaiki dapat berfungsi kembali.
I suspect it was a perfectly clean and functional amp before he took the lid off and covered it in sawdust to make the video.
Totally Agreed👍
Si tienes razón es lo que hacen muchos los ensucian un poco para hacer el video y decir que es una restauración
17:36 - what test is this? it's an absolute falsehood! This is no kind of a test for electrolytic capacitors, plus he's 'testing' them so fast he's not even letting the needle settle : )

Гениально. Разобрал, помыл водой, собрал и все заработало. Ещё раз, гениально
Супер мастер, включив усь кнопкой и увидев что даже вентиляторы не включились, начинает разбирать до болтиков и мерить платы самого усиления..., а плату питания самой последней.

Isso sim , é um restaurador. 👏👏👏👏
O cara limpou , LAVOU as placas ....... é isso aí !!!
É muito triste quando aparecem uns " restauradores " que não tiram nem a poeira dos componentes e já sai montando.
Dá pra ver que o amplificador ficava em uma serralheiria. muito pó de madeira
Os asiáticos são excelentes restauradores...
Puro pajaro nalgon.
Реставрация, которую мы заслужили (нет)... Если б каждый мой ремонт заключался в том, что печатку надо потереть щеточкой😂...
Так этот рукожоп то изначально знал что все рабочее. Сам же заранее в него пару лопат пыли и насыпал
@@flashgarage да, заржавело все, пластик трансформаторов, транзисторы, все. И ржавчина отлично сдулась пылесосом.
😀😀😀
@@flashgarageвидео для идиотов ,промыл со шланга водой ,потом мылом платы ,щеточкой все почистил , да если было бы так все просто .люди восхищаються какая добротная работа .я в шоке от этого бреда
You went through all of that trouble and didn't clean the pots, switches, fuses or other contacts? I've done quite a few restorations and I would never think of bypassing a deoxit cleaning of all of the contacts on something that was that dirty. I would rather forgo the paint job than skip those.
Кто-нибудь знает, зачем взяли исправный усилитель, насыпали в него песка, а потом долго отмывали? Надо было для полноты картины ещё трансформаторы размотать, протереть проволоку и заново намотать :)
да-да-да-да, я о том же сначала подумал.
Конечно же это для контента на ютуб
Надо ему реально замученный усилитель мощности послать (после неоднократного ремонта специалистами широкого профиля),🥴Я в том году взял за штуку радиотехника у 101, было ощущение, что его сгноить пытались,а перед этим убили напрочь(ключи сгорели,по паре П307 в усилках,две к157уд2,ну и армянские конденсаторы,а как без них 😆)пришлось ортофосфорной кислотой ржавчину выводить,в общем починил по-приколу, в принципе я никогда не был в восторге от его звука,в итоге выкинул оконечники и влепил сборку 2*80Вт и трансформатор для него.Осталось только с блоком регулировки нч вч что-то намудрить, там ведь к157уд2,а они далеко не айс.
@@user-qu9mg5sy4k капец вы конечно апостол Матфий:D

Que trabalho maravilhoso, parabéns, top demais, eletrônica nesse nível é para poucos. Parabéns
Muito top este ambrificador👍👏
Весь принцип реставрации на ютуб: от простого гвоздя, до сложной электроники - отмыть и перекрасить!
зачастую хватает просто отмыть окисления со схем мпиртом))
@@petrmelnik9935так он не спиртом аккуратно протирал ,сначала промыл ,продул ,потом платы мыльным раствором и все . Я свой залил чаем целый день ватными палочками со спиртом дорожки чистил .А здесь все так просто ,и главное все работает ?
@@user-uz2sh1qu8v Это нормально когда моют платы мыльным раствором. А вот загрязнения оч специфическое) Типа загадить устройство чтоб потом на камеру отмыть и запилить контент))

In our time, when people can only move their fingers on a smartphone, such videos are of great respect. RESPECT !
True, my friend!
Truth and even then its only to criticize other peoples achievements.
Постановка!!!вечно одна и та же грязь а компоненты в идеале.😂😂😂
4 диода заменил все же.
@@MrYurAlex ну надо же было паяльником что-то по колупать😂
It would be a good idea to clean the transformer connectors and fuse holder contacts. They are definitely not metallically pure and will have contact resistance. This causes them to get warm and possibly run away.
Still a good video, great to see it back and running bravo!!!!!
Tôi rất yêu thích nghề điện tử phục hồi lại đồ cũ là một điều tuyệt vời mà anh đã làm được chúc mừng anh.
Totally impressed with the attention to detail, well done
Как всегда ремонт при помощи тазика с водой и кисточки
А уж как классно проверил и восстановил конденсаторы фильтра! Блеск!😂
At 33:10 it appears to be playing with the power switch off. Also it's fine to wash whole intact amplifiers as long as you let them dry out fully afterwards. I've done it many a time; even with valve amps with the valves removed and transformer shroud holes blocked.
Почему такие каналы не закрывают из-за обмана ???
Полностью согласен с вами ,водой промыл со шланга,потом платы мыльным раствором , и все работает ! И кто то восхищаеться этой колхозной работой😊😊😊
Насыпал земли и типа восстанавливает. Открутил крышку под которой чистёхонькие конденсаторы.
Я ждал что он трансформаторы перемотает, без этого реставрация неполноценна :).
Потом эту шляпу на Али кому то продадут
Hindi naman yata sunog ang transformer, bakit siya mag rewind?

É BOM VER O TRABALHO NOTA 1000
Taki niepewny sprzęt włącza się ZAWSZE przez żarówkę, a dopiero potem wprost do prądu panie majster!
My friend from Poland just said : Such an equipment should be ALWAYS starting with a light bulb on paralell on AC ! True ! Lot's of my service work circuit has a common revive process . On " LIVE" part I use 6 A fast "S" type fuse , Light bulb ( 40 - 300 W ) in paralell , just build in permanently on my bench . Lately i use heat IR camera to monitor excess heat on PCB's and UV Light , to detect any spills maded from an outside or inside F.E. from electrolytyc capacitors or battery spill .
опилки с песком посыпал предворительно - нет тут никакой рестоврации - постанова
I see the two mains fuses are 16 amps into a PC board. Assuming you are in Europe at 230VAC x 16A total = 3,680 watts max. Leaving a little room to prevent fuses blowing every hour at full volume, let's say 12A working load. 230V x 12A = 2760 watts in from the mains. The amp is a direct coupled analog amp, so it's about 35% efficient to get great harmonic distortion numbers the audiofools insist on. 2760 x .35 = 966 watts /2 channels = 483 watts/channel....into probably 2 ohm loads. 483 into 2 ohms, 242 into 4 ohms, 121 into 8 ohms per channel.....hardly the 4KW RMS promised. 121 watts RMS will smoke most consumer grade speakers! Less than 2 ohms the lines of transistors melt but will blow the 16A fuses or pop the house breakers before the fire...
Shhhhhh....Never mention math when selling stereos!
This is not an amplifier to use at home at 2x 2000W, and concert halls etc tend to have 25/32A outlets for these. At least they do here.
@@klonik79 True, it's targeted at clubs, discos, cinemas and auditoriums etc, specs claim 3760W RMS @ 1%THD bridged into 8 Ohms, 2800W/ch into 2 Ohm, rated power consumption at maximum output 6760VA.
The mains plug is US style and it seems the place got 115 volts mains. In US a 230V mains plug looks different.
An amp of such caliber it runs in a professionel sourronding on 230 fused with a 32A outlet, such as CEE series plugs.
Walaupun saya tidak punya power tapi saya suka lihat orang servis power di youtube dan anda yang paling terbaik..❤❤❤👍
Genial muy buen trabajo por la restauración 👌👌👌👌👌
Aquele pó de serra não me convenceu não, mas este é um belo amplificador e não é tão antigo assim.
From the current amp model
show de bola. da pra ver que o amplificador foi bem projetado, só pelo banco de capacitores já da pra ter uma idéia. sem contar que é um classe A-B nada contra os classe D mas prefiro os classe A-B
Eu também prefiro. Há uns 3 anos atras eu comprei um OP5500 da Oneal, estava todo detonado. Ai mandei pintar o gabinete e consertei os dois canais. Está funcionando até hoje.
Усилок - прямо как только что найденный на пустоши Фоллаута...

You are quick in diagnosing electronic components. Restoration done with good quality, the result was excellent.
Fantastico,do inicio ao fim
Prepare it to restore and making it rusty and dusty is so much difficult than restoring it...please share the video how you make it that bad...and dusrty only from top without spider webs!!

EXCELENTE TRABALHO, PARABÉNS
Perfectly clean after he blew out the sawdust that he had only put in before he started the camera.
looks to be it had a long life banging tunes in some ones workshop.
Очередная залипуха. Сначала насыпал в исправный усилитель пыли, затем героически его якобы восстанавливает
There is a guy here in the USA that restores like you...he had a receiver as dirty as yours and took it to the car wash, pressure clean it, then pressure air from a compressor and finally put it in the oven at 120° for 40 minutes...and guess what...it came out brand new...is good content also...cheers.
*_Super-impressive, fascinating, satisfying, and just beautiful to watch. Great job!_*

Не видео, а сплошное вранье. Судя по состоянию, это чуть ли не новый усилитель, который засыпали опилками.
You have a great skills by restoring all these amplifier devices.
Excellent restoration ❤❤❤❤
У меня впечатление, что его (концертный усилитель),"гоняли" на пилораме 😆 Недавно приобрёл подобный, 2 канала по 600W, думаю за лето сделать акустику круговой направленности.С мощностью акустики пока не определился, поэтому взял с запасом,буду брать динамики НОЭМА .
@@softas01 так и есть. Пол Ютуба таких реставраторов всратых
Good job! Modern lytic capacitors seem to be very durable, or weren't that old in this amp. I was also surprised all those flat cables with their connectors still worked despite only having control signals on them; too many companies working with tubes are using them for like 300Vdc up to 30mA, this will start failing like crazy in less than ten years... Diodes probably measured fine (didn't see the other polarity) but such bridges do fail with heat, soldering, etc. Oh, THAT VCA was interesting find, probably works for some kind of limiting or metering, can't say.
Thanks god we still have people doing jobs like this instead of throwing things away for no good reason. See you in 15 years or so :)
See You on restoration front , not in another dump hole :)
@@madmadecki1890 I'm only interested in flat cables with conn., durability of lytics or other things of this sort here, no dump holes sucking life out of gear.
Congratulations, exelent job.

La prima cosa che mi è venuta in mente vedendo il filmato e quello di ricordarsi di rimettere è tutti i cavi come erano prima. Bisogna essere dei fenomeni. Io una volta cambiai il timer della mia lavatrice e dovetti segnare tutti i cavi per rischiare di non sbagliare. Sono bravi veramente questi ragazzi.
Самые дорогие детали оказались целыми (выходники, конденсаторы, трансформаторы) , заменил только диодный мостик(видимо для питания платы защиты-управления) отлично все почистил, чтобы потом по грязи не закоротило. Отличная работа.
Di sini tidak ada orang yang buang barang seperti itu. Kalau ada pasti saya akan buat seperti yang anda buat.
Pekerjaan hebat, bagus...
Rất chuyên nghiệp cảm ơn bạn đã ra vi deo
Pretty risky plugging in something in that condition with massive power potential and huge capacitors without a regulated power supply. 😮
He was fine, he had the Chuck Norris rubber sandals ⚡⚡⚡
Where did you buy this unit Mr. Electricity ?? What was a cost of the used unit too ??? Thanka
Big job thanks for the video. I just would try to turn on the piece before servicing it. Also, you need to replace those big caps friend they will leak soon. The glue you remove is crucial for vibration damage the solder points specially if they're sideways. All these is future proofing.
That's a current model amplifier that's still available to purchase new. I don't know how long the model has run, but even if it's a few years old, little reason to suspect the reservoir capacitors. I agree he should secure the capacitors against vibration stress, the service manual for that model is specific about requiring that! Common sense too.
Great restoration. You did very well.
Nikt i tak nie zrozumie tego komentarza ale zawsze zastanawia mnie jedna rzecz. Ktoś kto posiadał taki sprzęt wiedział że to jest sporo warte więc mimo awarii czy nie użytkowania dziwi mnie jak można było zapuścić taki wzmacniacz lub go po prostu wyrzucić??? Chyba ktoś go posypał celowo jakimś brudem do filmu jakiś czas przed nagrywaniem żeby wyglądał na zniszczony. Dodatkowo, wzmacniacz się nie włącza a ktoś zamiast zacząć od sprawdzenia przewodu, bezpieczników od razu rozbiera sprzęt na części xD
Кому ты чешешь ? Сам насыпал сам и почистил
Parabéns pelo trabalho
Hermoso amplifocador increíble los.disipador excepcional
Pra ter ficado ainda melhor, ele poderia ter colocado abraçadeira helleman na fiação, pra dar um melhor acabamento, mas está de parabéns pela restauração !
Sure wish you did a narration over it describing what you’re doing, and what the parts are called.
I do not think he knows what the parts are called.
That amp is about 3000 euro, nice job!!
Если бы у меня был такой усилитель, то жена мне не нужна. 🎉🎉🎉🎉
Your restoration are awesome so real ....Not like the other restoration just manually doing some mess themself , already knowing the fault just for making the video .... Great work 👍
What he did there could have been achieved with nothing more than pressurised air
@@dimbwemazala8978 yes and don't dump saw dust in it before you start. and use a hoover to suck up any real dust lol fake shit this is
This is my take on it
Fake as shit. e.g. every test on the toroidal transformers where done on the same multimeter settings, but lets pretend it was real, then every winding was burned out according to the test results. lol. The amp had no dust that normally builds up but was full of wood chip dust from the machines in the workshop. wood dust wont damage the amp and can be easily removed so good choice for fake crap. the capacitors could not be checked with that stupid meter lol another piece of crap. The whole thing is a staged fake video. The diode test was ridicules, All the new diodes failed the test and then failed again in the test in reverse , But this readings would be correct for a good diode if the diode was facing the other way. So there is fake stuff going on here.
The bridge rectifiers all checked out as blown useless but the reverse fail wound be a pass. So I think the multimeter has one of these bogus repairs and they put the internal positive test lead to the negative external plug and the negative on the positive plug. Theis guys don't know the difference. This would explain the reverse readings they are getting . This means it is all fake . Also when they replaced the diodes in the board they all failed again because the other component's where also getting measured
your restorations are excellent and true, unlike some who do fake restoration, congratulations!
But it's fake if you have knowledge about repairs u know it's fake. 😂

Thank you so much sharing Information Video Good working Big like stay 🌻🥀🥀🌻🥀📌📌📌📌📌📌📌
So great job! I have found various electronics in this state before as well. After all said and done what did you replace and how much time did you take to clean it up? Restored is defiantly a correct term. You went the distance :)
En efecto, es un desafío. Y salió triunfante!
The restoration is very good! but why do you always need to make some fake measurements with the mutimeter? For example when you measure an IC from pin to pin 🙂
He was checking resistance on the power supply wires to make sure none of them were dead or shorted. You don't necessarily have to power up a power supply to test🎉❤😢
@@SS-mj2mq hi, no trust me, I am an electronician. He is doing measurements pin to pin on an IC. That does not make any sense :-)
@@JeromeLouvet I do electrician will work myself I also engineer and build custom amplifiers wire has a resistance the longer the length of wire the more resistance transformer is no more than a magnet field with wire wrapped to create resistance. You have your primary winding and your secondary winding.
@@JeromeLouvet some transformers have a thermal fuse that can blow and therefore it can cause the wire not to touch. Wire can become frail or even burnt to a crisp it's nothing more than copper coated with enamel and there won't be any resistance if the thermal fuse blows and power or current will not be able to flow around the outside of the wire I also do have electrician experience as well.
@@JeromeLouvet they also use a copper enamel wire 10 gauge 20mm Turned about 15 turns and use it as a choke for the output part of the amplifier with a resistor as well as a relay or fuse. It is part of the zobel network.
Muy buen trabajo estimado amigo , saludos desde Lima Peru .
Just blow it out with air then take the garden hose too it. Just make sure it is 100% dry before plugging it in.
I just got a pair of Peavey SP-2 ti PA speakers I am in the process of rebuilding. One box is missing the 15 inch Black Widow sub and needs a new driver for the horn. But I believe I got one of them dialed in with a fresh cleaning and some new shiny paint in places. Dude slow down on the bomb can paint. 1st three coats need to be light dust coats. Let it dry for 30 min then come in with a medium light few coats. It is not a race to see how much paint you can put on the case. Most spray paint is enamel and that takes a while to dry. When you pound it on it cannot vent off like it needs and with remain soft for a long time. 1st coat you should be able to see metal or sanded paint under it. really up into the third light coat. Once you got the mostly dry light coats you got a nice base to come in with the medium wet coats. A good three of them with dry time of 15-20 min in 65-70 deg. weather (Fahrenheit). Put in hours of work to clean up they unit just to paint it like sh!t. Ya see guys do that with hot rod builds. Put 10's of 1000's of dollars into a rod just to skimp on the paint and ruin it.
That's an entirely fake amount of dirt and dust. It's the wrong color, it's too evenly distributed. FAKE FAKE FAKE! Downvoted.
In india thats normal HAHAHA
That’s real dust, you can’t fake that
A tutorial on how to create a fake device repair video.
Take a working device.
Sprinkle sand, dirt into the housing.
pour some water( optionally mix water with salt and cover some parts to rust quickly).
spread the dirt in the housing.
Remove the fuses so that the device does not start ( or put the damaged ones).
Show that it does not work.
Disassemble all components.
Wash each component in turn.
Paint some part of the housing.
Pretend you are repairing something, use a meter that has no capacitance measurement to check electrolytic capacitors....
Put the whole thing together, start it up , show that it works.
Most of the videos that are made by people from these countries are fake.
I am involved in the restoration of antique and modern audio equipment, and as I watch such videos I can not believe that someone is fooled by such a scam.
To repair such devices you need RLC bridges, distortion meter, an oscilloscope, a generator, a load, and many other measuring instruments to get the job done right.
After the repair, the amplifier's operating points should be adjusted.
This and other videos are ridiculous and so untrue.
He has no donate button nor PayPal in his description...WHY WOULD HE FAKE IT ???
@@BPantherPink are you kidding me ?
Don't know how monetizing on youtube works ?
The more views, the more money the author of the video gets.
You make money by displaying ads during the video.
He will make more money in a month on such silly videos than you will in a year.
I found it very funny putting the meter across the MosFets without removing, and also the varistor on the power supply ridiculous!!
@@DanHomeAtLast I consider your comment here is the best... Upon putting power on the beginning, knowing that it don't power up, then without any small trouble shooting first is a red flag already. And as your comment, you are correct. That is not the proper way to test it. i consider it as fake testing of a person that does not know what he is doing.
True

Its rewards function again a machine..
Hello, I also restore old devices,
for cleaning the circuit boards I use spray cleaner for sinks and bathtubs, it goes much faster, after spraying the foam, just rinse with very hot water or with a diffusion of steam.
Even on electronics
lamps it works perfectly, of course you have to dry then in the open air,
or spray ethyl alcohol if you want to go faster!
I was thinking it was ethyl alcohol myself. Based on what I noticed in the rest of the video, alcohol would be a cheap, efficient, and available cleaner to use.
Unfortunate to see that this machine was first intentionally ruined just to make a restoration video. How fake restoration video has become an industry now
