Very nice - until he painted the heat sinks ... 😏😏
Hats off to you man. I will never looked at old stuff the same way now that I saw you repairing this. Thanks
Amigo mío: es usted todo un artista......No me cabe la menor de las dudas............Impresionante labor de restauración de ese viejo y magnífico amplificador de potencia.....Enhorabuena.........Un gran abrazo desde Las Islas Canarias (España).........................
Oh my god... You Is The Best!!
Congrulations!!
I like this video it good
When eating during these videos I power through my lunch @x50
I admire your Patience...👍1️⃣🔧!!!
Good afternoon! You are just a genius! I have not seen this yet, I watch your videos and I can’t believe with my eyes that this is possible! I wish you good health, family well-being, warmth, love, creative inspiration, as well as financial prosperity in monetary terms! Good luck to you, success, and prosperity to your channel!!!
You shoud believe your eyes :) It's impossible.
Wonderful job brother !!! Congratulations from Brazil
You are a good pro tech. 👍👍
I like when you sprayed on the rusted case.....
No abrasive clean, no rust treatment....
And it is not really wise to paint cooling blocks. These are not "painted" black but anodized to multiply the cooling area by roughing up the surface. Your paint will hinder the heat exchange now.
You make it look so easy. Maybe I could do this too ? Maybe not. Good job. Thank you.
สุดยอดมากครับ
Nice restoration amplifier👍👍
Надо же, случайно видео попалось! А я полгода назад такой как раз ремонтировал, только под брендом Sounstandard. Не так досконально, конечно, как тут, но всё же немало дел сделал. Тоже менял выходные транзисторы, чистил ручки, также были выгоревшие нагрузочные резисторы 0,33Ом - их потом заменил все (28шт) на 0,47Ом, чтобы немного разгрузить выходные транзисторы и более равномерно нагрузку распределить. Также был один стабилитрон сгоревший на одной плате, попутно и операционные усилители поменял (вместо JRC - NJM). Сейчас работает усилитель в одном из клубов. Респект за ремонт и видео!
A gde v video remont?
@@whynot6795 это ремонт, друг. то что оне его вконце покрасил это не сильно меняет ситуацию. Вообще огонь работа.
@@Pacca33 Esli vy slepoj to da, dlja vas eto remont :D. Dlja menja eto smeshnoe video pro to kak isportit'. I znaja czto etot komik delaet dovolno xorosho vidno gde on podmenjaet usilok. Edinstvennoe chto mne interesno eto chto za xemiju ispolzuet dlja togo chtob metall bystro porzhavel.

eres un verdadero artista de la reparacion te felicito un fuerte abrazo desde el pais vasco [España]
It's a shame the guy taken everything apart but did not replace the capacitor, ??
สุดยอดครับ👍👍👍👍🇹🇭
Nice, please paint front panel also
Very good restoration 👍👍👍Thanks for sharing
Looks like you did a great job on it. The only thing I didn't like was that you didn't sand the rust down and fully repaint the chassis. Also I would just replace those old noisy fans and screws.
Amazing job. Well done.
How beautiful is that National/Panasonic NP3935TZA torodial? 200amps of modified sine wave! The smaller brother of this torodial could power a small city, god only knows what damage this bad boy can do! The late, great Nitishika Yamitomo sure knew his torodials! 🙏🏾🙏🏾🙏🏾
Đẹp quá đỉnh của đỉnh
Un aparato que no pasará de moda nunca
That is not a knife now. It's a work of art! Beautiful!
If one power cap failed, the rest are soon to follow. Probably won’t last a few hours of operation.
Que Bárbaro!!! Eso es paciencia!
SUPER.👍👍👍👍👍
100% инструмент которым он пользуется их тоже отреставрировал)
6:53 the screams of the capacitors leaving the pcb
🤣
Хороший видео материал
Super!🔥👍
당신은 아주 유능한 기술자입니다.
Awesome job ! Love to see all the process and how it is done 🥰 Of course, each case has it's differences from other case's.
Oh yeah. But author shoud pay more attension to details. It;s easy to see that amp at the end is not painted and with dust inside.
You are genius sir great
Una buena limpieza y espectacular y muy buena
Genial...gracias!!!
anh này giỏi thật
Why would you paint the heatsinks!? Without treating the metal chemically the paint would not stick and worse, flake off as the transistors heat the assembly up. Just asking for trouble for the sake of cosmetics. You have not done that before. Ill advised. Also why not change all the caps? Just to be safe.
He is a Vietnamese double degree in electrical engineering and computer science, so I think he knows what he is doing.
@@Prometheus574 Replacing the caps would've been his first priority then. He would also know that that moving coil meter is useless for testing caps. They're rated at 50v so almost guaranteed they've been over volted. Why no esd precaution.
That is true. Always start with new low esr caps. And don't paint heatsinks... Heat transfer will be lower. I'm not an engineer but im building tube amps and class a transistor amps. Only use 105°C Low esr elco's. If they fail the rest will fail. You do not to be an engineer to knowing that 🤔
That is thermal paste
@@Prometheus574 So what do you know about his double degrees and all this stuff do you know him personally or are you just privy to that information
nice job bro! i wonder why in the filter capacitor and transistor section there was an empty row? i guess that is for a more powerful model amp?
VERY NICE WORK COOL
Excelente
Pls,add subs about your actions!Great work.
Bravo !!!!! great Job !!!!
Good job - but are they using petrol to clean the PCB's with??
Good job
Just subscribed because I have a lot of learning to do! ☺️
Regular trabajo, pero buen video
Ты просто топ 😄😃😅😁😁
Gracias por compartir tan bonito video de Reparación del amplificador pero el disipador si no sé pinta xq produciría cortó en los MOSFET pero lo k si estuvo bien explicado fue el cambio de componentes eso sí lo lógico gracias x compartir tan bonita horientacion sigan adelante...... admirable es cuando construyen las cajas para los bafles sigan adelante.....
Small rectifier bridge, and low voltage of electrolytic capacitors, in view of the large transformer and the large amount of output transistors.
Maestro de maestros
Magnífico
Not so long ago I put 8 impedance fans in the park audio vx1800 2/500 W amplifier instead of those that I put sunon dc 12 / 3.6 v magnetic levitation on bearings, they work great!
very professional.good joob bro
Would of recapped the entire unit, and replaced the transistors as matching set.. but that's just me.. because if I own it's definitely gonna see a 75% load at long duty cycles.... otherwise nicely done. - Surry Virginia
Mantap biar suda lama alat ya tetap ada untuk ganti komponen ya
very cool
Wow, after all that work you should have cleaned up and painted the metal case.
Молодчага! Оно того стоит - этот богатырь ватт 250 на каждый канал даст в лёгкую!💪🤩
Good work .. i am dhanasekar from Coimbatore , Tamilnadu India
Complimenti bravo 🙌
EXCELENTE!!!
Un buen mantenimiento
This channel has no fake restoration videos. In the videos, the electronics are just disassembled, cleaned and put back in, but they are doing their best in their given tools.
He also changes everything that’s not working anymore
Take our sunglasses and watch more carefully. No fake restoration LOL 😁😁😁🤣🤣
i wouldn't have him fix an amp for me so many bad practices and things not done
looks well made. all metal oxide resistors
es una buena en señansa
28:34 pretty confident in your wiring I see. Don't want to get zapped first thing in the morning.
Very good!
Super viedo bro
Good....mester
21:01 there's nothing a beer cannot solve 🍺
I saw the same thing! I thought he was just using old isopropyl then I noticed it wasn’t evaporating, then I saw the beer bottle! 😧
I think should not be sprayed with heatsink paint.🤔🤔
Â
Q
Totally agree! It lessens the heat dissipation of the heatsinks
It would be cool if you tested the performance on a dyno afterward.
Супер 😃😃😅😁
Maravilloso
Why not add 4 extra 50v 10000uf capacitors when the solderpads are there?
Nice vidiou
Te admiro amigo
Алюминевый радиатор нельзя красить.
Ему можно, у него же спец. краска, новым алюминием обрастает :D
@@cherbet Это лак, а так надо анодировать.
buen trabajo amigo, solo una sugerencia, antes de desarmar una sopleteada para hacer mejor trabajo. felicidades
Good
good luck with your hand
Un clásico de clásicos
Muito bom 👏👏
dummy load , signal generator , watt meter testing?
Una buena limpieza
Te felicito por la restauración de ese amplificador, si que vale la pena restaurarlo, gracias por su vídeo, saludos cordiales Nezahualcóyotl México.
И обязательно возьмись обеими руками за оголенную розетку !
И конденсаторы омметром проверяй
Thank you for this wonderful art. You have an amazing gift. Keep it up.
Es admirable
I like watching movies like this, you show that you don't need to throw anything away, you just need to fix it 👍(i used google translator)
If you have plenty of spare part source like him, yes. Otherwise, good luck finding those faulty components :)
I hope you are waching these videos backwards? I mean how woking amp is fucked.
В 22-м году пакистанский ремонт, да вообще все пакистанские технологические процессы в тренде ,особенно работа в шлепках при литье чугуна ))))
Классная работа !
Интересно, как звучит этот здоровяк ?
este vídeo is motiva a los que le gusta este mundo excelente.
Так это он пивом моет платы!!! :) а я то думал, что за волшебная смывка :)
29:00 great work . by the way you can add an audio mixer in the front
Good job bro
