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.

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.
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 : )

@@robinsutcliffe-video_art plus at least 2 of the Capacitors appeared to have Raised Caps
Гениально. Разобрал, помыл водой, собрал и все заработало. Ещё раз, гениально
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.
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.
this is not restoration..but just cleaning
i guess you missed him replacing 4 resistors. You. probably should watch the entire video before you open your mouth
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.

Sobrang husay at matyaga maglinis ng parts...good job.
Que trabalho maravilhoso, parabéns, top demais, eletrônica nesse nível é para poucos. Parabéns
Totally impressed with the attention to detail, well done
Muito top este ambrificador👍👏
Mega geil kann man nur sagen macht richtig Spaß zu zuschauen Respekt an den Restaurator. LG.🤗🤗🤗🤗🤗
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
это где такая страна чудес, где усилители рабочие выбрасывают?)))) не ведитесь.
Genial muy buen trabajo por la restauración 👌👌👌👌👌
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
Great job! The new screws really finish the project. 👍🏻👍🏻
You are quick in diagnosing electronic components. Restoration done with good quality, the result was excellent.
he doesnt discharge capacitors after poweron?
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!!!!!
Parabens mago da eketronica❤
Great restoration. You did very well.
Muito bom o seu canal, parabéns!
Deus abençoe muito você e sua família
I used to have a crown that I rebuilt and sold then bought a hafler, That's a mess but I love those transformer coil's. Great job, I respect your attention to detail and it's the only way to go. o7
Nhìn ông chuyên gia tháo lắp : kinh hoàng , Bái phục . Quá giỏi . Xin cảm ơn .
Aí sim 👍 trabalhou de verdade sem preguiça nem uma. top parabéns ! eu só um inscrito aki por mérito seu parabéns novamente... cara ki show de manutenção vc apresentou gostei muito .!!
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.
Excellent restoration ❤❤❤❤
Walaupun saya tidak punya power tapi saya suka lihat orang servis power di youtube dan anda yang paling terbaik..❤❤❤👍
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 .
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.
Глаз радуется! 👍👍👍👍👍
É BOM VER O TRABALHO NOTA 1000
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😂
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.
You have a great skills by restoring all these amplifier devices.
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))
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😊😊😊
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.
Fantastico,do inicio ao fim
Wonderfull work like always 🫡
More power amp videos mate 🤜🏻🤛🏻
Mas que beleza de trabalho. Profissional bacana d mais. Parabéns. Belíssimo amplificador
Parabéns excelente trabalho
Hermoso amplifocador increíble los.disipador excepcional
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
Where did you buy this unit Mr. Electricity ?? What was a cost of the used unit too ??? Thanka
Wow Heavy Corotion Seek, But You Do Best Technition.Job To Prepare The Corotion Amp . God Bless You, Thanks All, ..... Cheerio.*****.
Əla gözəl işdir, təşəkkürlər.
Насыпал земли и типа восстанавливает. Открутил крышку под которой чистёхонькие конденсаторы.
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!!
Great work ❤
Watching idol thank you for sharing this
Wonderful thank you for sharing AND keeping another piece of equipment working.
Que restauração top parabéns trabalho com eletrônica também amo muito isso 👏🏼👏🏼👏🏼👏🏼
Excellent job👌👍
Great job keep up the good work nuff respect 👍🏽👍🏽🙏🏽👏🏽
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?
опилки с песком посыпал предворительно - нет тут никакой рестоврации - постанова
EXCELENTE TRABALHO, PARABÉNS
Muy buen trabajo estimado amigo , saludos desde Lima Peru .
Усилок - прямо как только что найденный на пустоши Фоллаута...
Как всегда ремонт при помощи тазика с водой и кисточки
А уж как классно проверил и восстановил конденсаторы фильтра! Блеск!😂
Вода и мыло, и будет магия. Спасибо посмеялся.
Согласен , потом этот шлак на Али продадут . Если бы было все так просто ! И люди восхищаються этим обманом я в шоке
Muito legal experiência total parabéns
Major work, well done
Olá! Parabéns pela restauração 👏🏼👏🏼👍🏼

Desde já agradeço.🙂

You're kidding
Mounstro de amplificador 😉👍
Woooow felicitaciones!!!!!
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.
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.
Bellissimo Lavoro!
Good job Mr .thank you for your sharing talent.full watching Philippine's
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.
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 ⚡⚡⚡
Parabéns pelo trabalho
Good knowledge and skill. i will find old amplifier.
Absolutely nice restoration !!
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
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.
Ah yes, the proverbial BOAT ANCHOR...
Thank you so much sharing Information Video Good working Big like stay 🌻🥀🥀🌻🥀📌📌📌📌📌📌📌
Miraculous how these guys remember where all the wires go. And we all know how often miracles occur 😕
Well, if they film the teardown process, then they remember everything
There is at thing called schematic diagram...

Hàng trâu Âu Qua các ông thật sin so
Well its very simple just watch again the beginning ☺️
Очередная залипуха. Сначала насыпал в исправный усилитель пыли, затем героически его якобы восстанавливает
Wow, awesome👍
Parabéns amigo muito bom
Не видео, а сплошное вранье. Судя по состоянию, это чуть ли не новый усилитель, который засыпали опилками.
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.
Congratulations, exelent job.
Im sri lanka ❤❤❤👍👍🔥🔥🔥🔥🔥
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

Rất chuyên nghiệp cảm ơn bạn đã ra vi deo
Fantastico! 🎉❤
Кому ты чешешь ? Сам насыпал сам и почистил
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
Beautiful. Great job.
대단합니다 🎉
