- Restoration Kenwood Stereo Amplifier KA 880D // Restore And Upgrade Old Broken Japanese Amp
kenwood amplifier restoration is my next project.
today i'm going to restore the japanese amp, it looks brand new on the outside, but inside the components are badly damaged. it took me a long time to get the amp working again.
The recovery video still has many shortcomings, looking forward to receiving your feedback so that I can build a better channel...thanks a lot!

When you see sparks when you plug it in.....it's always a great idea to plug it in again.
yes/
Yes 😂
Better do it one more time just to make sure its warmed up.
You had me until you clear coated the front panel :(
Yeah, these devices look better with a matte clear coat.
@@christianrottler there is no clearcoat on them, it's matte anodized aluminium
Who are you and why does your opinion matter?
@@ingenfestbrems I’m a viewer. And why does your opinion matter as well!?!
Taking out and cleaning the capacitors always makes them work again.
Obviously.
Сначала сжечь усилитель , а потом его ремонтировать. Феноменально. Мастер от бога.
...yes,
@@restorerestoration4705 хаха
Got rid of the bad ju ju via, electrical exorcism, put in new smoke.
Они разные,разбирал один спалил другой
больше порадовала его "паяльная станция")))
the thing is, it's burning but inside there are no traces, whether on the cables or the circuits.... He spray paints the facade black but the yellow inscriptions are not covered by black paint! It's truly magical..... you're a good guy, you should get an engineering degree.
Clear coat ;)
Gave life to another antique....👌
Thanks for your feedback
nice job! But please, someone get this man some modern day equipment! That voltmeter and soldering iron are older than me. lol
yes..
Нельзя давать этому очень талантливому человеку современные инструменты. Он же все вокруг починит и отремонтирует! А паяльник действительно крутой.
He borrowed them off Moses, after he finished his new led lighting on his ark 😂
Работа спустя рукава!
Ok amigo
Looks like it was in a flood!

Where a Variac comes in handy. bring up the voltage and if the current starts to climb too high not exponentially to the voltage, you know there is a problem and before you blow something.
the thing is that he is not supposed to touch eletronics, i guess this repair is also fake.
🤔🤔...?
@@restorerestoration4705 Cables dont seem to melt this way if a good Amper Value fuse installed there. Thats questioning.

Well, if you repair something that’s broken that’s really expensive you just saved money🎉 🎉🎉🎉🎉🎉🎉 🎉🎉🎉
Thanks for your respond
Very good staged 'restoration' project. Sadly you missed a few things which indicated that the amplifier was made to look old, corroded and failing in a spectacular way. But entertaining none the less.
...yes..🤔

Bruh his soldering iron and solder WICK is older (vintage) than the damn radio he fixing. 😂
The opening is hilarious!!!!
А они та разные,вскрыл один а разбирает другой.
still have my kenwood KA-880SD and GE 1100 equalizer bought while in service in Okinawa around 1987 pushing my Infinity SM150's

И так сойдет! Выходной каскад я не увидел что проверялся... Сверкало норм, а что сгорело? фиг его знает... нет следов. Предоконечный без следов транзисторы... Я думал дорожки погорели или кондеры, а там маломошные транзисторы типа так сверкали... Но на них нет следа прогара! ??? Что за фокусы???? Но краскопульт конечно у вас самый любимый предмет... А вибро ванны... А химические реагенты от ржавчины? Но усилок то заработал... Правда со спецэффектами! С новым годом! Пойдет видео! Давай еще. Лайк за феерверк!)))😀
Никакой магии тут нет, типичный видос для ракушек, сперва берем целый аппарат снимаем его на видео как все работает и тд затем херим его , несколько кадров с мультиметром и паяльником, остаётся только смонтировать все в правильно порядке, так делают 90 % таких псевдо реставраций
@@user-sm2hy8nx3b Ага, я тоже раньше верил) Сейчас сначала диз леплю, потом уж ради интереса минуту-другую смотрю
Эх, всю жизнь занимаюсь радиоэлектроникой, покупаю всякие мультиметры, осцилограф, ищу схемы, изучаю, потом роюсь в самом аппарате.
А надо то оказывается: как-нибудь захудалый тестер, пофиг какой, лишь бы стрелка дергалась, реагенты, вода и краскопульт с красками. Всё!
Век живи, век учись...☝️😄
Постановочное кз, обратите внимание что после замыкания он еще сильнее вставляет вилку в розетку а не пытается её выдернуть...
Try using flux while soldering. That way you won’t get that brown schmutz after soldering. Plus, copper braid should be moved after absorbing solder, because using only one place might not absorb all the solder.
oh look a youtube expert eager to give its expert youtube advice

Yeah, kinda looks like it. Thanks for pointing it out@@Atelierul29
This man is a rock star of all things in need of restoration. He is unflappable.
Thank you for your feedback so we can better improve future products. Wishing you and your loved ones good health
Blindly switching on the amplifier without first cleaning and checking essential components is unprofessional and can lead to massive damage to the circuit board and the previously intact components. Before anyone gets upset about the criticism: I have a master's degree in radio and television technology and 45 years of professional experience in the field of audio-, video and power-electronics in the areas of service, production and development, I know what I'm talking about
Amazed at his confidence of his work. No bringing up with variac or troubleshooting. Congrats.
Dont be afraid.slowly think.this amp very easy repair
Whenever you are testing ANY ELECTRICAL products, ALWAYS connect it via a SERIES BOARD. This SERIES board has two paralled 200W filament bulbs, but in series with the load . This avoids sparking, flashing etc of the electric product.
thank you very much
Man change those capacitors!!! From usa
I only can imagine what happens behind the scenes or can I ?
Ты парень, пиротехник😄
🤔🤔🤔🤏🤏
@@restorerestoration4705 мастер, молодец! 👏
Yes
Ever hear of a variac?
I am most impressed. I’m afraid I’d have scrapped that amplifier, I never believed it could function again. Very good work. 👍🏻 from USA.
yes..thank you
i assume he likes doing this, because that receiver is not worth all that work.
what you mean.Burn it,or to clean?
This is most unprofessional repair attitude I ever encountered. You were causing more damages by applying main voltage without first checking the internal conditions of the set.
At least, clean the set up before attempting the repair.
if he knows to fix increasing some burnt parts isn` t a matter for him
Thanks
bullshit! destroyed!
I'd say that the burning was purposely staged for effect.
This fraudster has filmed himself pre-crapping his fraud 😠
Still enjoy my mint condition Pioneer SX-1080, daily. Bought it in Okinawa Japan when I was in the Marine Corps, back in 1987. Think I paid about $450 for it, at the Military Exchange (store). Been offered as much as $8k for it. I'll never part with it...what a great receiver it still is...and has never been serviced.
Thank you for your feedback so we can better improve future products. Wishing you and your loved ones good health!
You should paint capacitors also
Saya suka nontonya
yes..
I had the 5060 years ago. Good unit.
Dude where did you store it im the grave yard so much mud no wonder is shorting out
Solder nya sangat keren...
yes..
Great job. I'd have gone satin top coat, as opposed to gloss. it's amazing really a couple of transistors brought it back. Well done.
Thanks very much . We will try in the next videos
No way was that bonfire repair a restoration
....🤔🤔
Thank you for the Details of the Kenwood Restauration... It is worth to safe the best time of Audio... 👍😊
..thank you
Current limiting device is a good tool to test equipment that looks abandoned. Its better to be safe with those old amps. Damaging original Audio Power Amp ICs or Transistors can be expensive . And if you're thinking Aliexpress will save you, there are lots of counterfeits ICs and Transistors for your "vintage" audio amp.
thank you
AHHH, the magic smoke!
yes..
Через лампочку включать надо, до сих пор не знаете что ли. Накаливания.
Thanks very much . We will try in the next videos
修理できて良かったですね。大切にしてください。
Thanks very much . We will try in the next videos
Nice job. By the way, what's the name of the music played on the Fiddler? Thanks for sharing.
Doubtful performance of the repair and equipment of the repairman heavy prehistory :) :)
I like the Asian sounding Cracker Barrel music.
And it will work! I didn't see the output stage, which was inspected... It appeared fine, but what exactly burned out? No one knows... there are no visible signs. The pre-terminal transistors also look untouched... I thought perhaps the tracks or capacitors were damaged, but it was actually the low-power transistors that were causing the sparking... Yet, there are no burn marks on them! What's going on here???
But of course, the spray gun is your go-to tool... And the ultrasonic cleaner... And the rust inhibitors? Well, the amplifier is up and running again... Though it comes with some special effects!
Happy New Year! A video is on the way! Let's celebrate with some fireworks!)))
Thanks for your feedback
Бог любит троицу, надо было третий раз воткнуть в сеть и обязательно включился 😂
.../??😃
Вот и сказке конец, а кто верит, тот дурак.
I’m here for the fire…🔥🔥🔥
А чего третий раз в розетку не воткнул, как раз бы руки погрел. Сразу видно настоящий мастер!
thank you very much
Мастер ломастер за критику ,даже спасибо говорит.
@@travel4188 это точно
Those smoothing caps look as though they were leaking - I thought he was going to replace them.
The whole thing is fake.
@@mstecker I think you are right
100V AC, whene it was produced?
Well done! keep up the good work.
Thanks for your feedback
Praises. You brought Amp back to life. Great work. 👏❤️🫂
Thank you for your feedback
Mult specialist și multă atenție... nu mai un calificat poate să fie sigur in electronică și precize vă stimez Bravo bravissimooo 👋👍👍👍✌️👌😘❤️
thank you..
Надо было подольше подержать во включённом состоянии. Ну кто включает технику в таком виде, без предварительных замеров. Если, конечно, это не инсценировка и порча изначально годного аппарата для "восстановления" под камеру.
yes..😇😇
через лампочку включать там не учили😂
@@xulliganchik88 yes, a lamp in with the power supply is a very good idea. I always do this with my tube radio restoration 👍
Так оно и есть постановка
@@user-lk6ki2uw7f yes,
How anyone would neglect their amp like this, is beyond me 😮. I think I would have binned it right away. FUBAR IMHO but you prove me wrong.
Thank you very much
Wouldn't it be better to replace the damaged parts (or at least those ones that looks pretty bad) first, and then try powering it on? This way those damaged parts wouldn't cause more damage, right?
This is completely fake. And yes you are correct.
yes...😄
well, plugging it makes spotting the dodgy parts very easy at least lol
@@ledoynier3694 hihi...
@@ledoynier3694 As we used to say in the Television repair trade, "switch on and tune for maximum smoke"
and this is why you use a Dim bulb...
Anyone working on an amplifier, and not using a Dim bulb for current protection.. Is a noob, and shouldnt be anywhere near electronics...
And the clear coat over the front panel.. Looks terrible!
Ok thanks
Ever apply reducted input voltage with variac to reforming the electrolitic capacitors.
Old Heatsink compound on output semiconductors must be removed and reapply new.
All potentiometers and switches need clean with appropriate contact cleaners.
Mold king, lead king, 10 of these repaired equals 1 year live expectancy…
Thank you for your feedback so we can better improve future products. Wishing you and your loved ones good health!
Looks like rectifier is short on the secondary, its best to use current limiting such as a light bulb in series on the mains side to prevent further damage. Secondly, its best to pull apart and clean the PCBs first.
Thanks for your feedback
Falta es armarlo
The failure of this amplifier is man-made. A power outlet can be seen around 1:57 in the video. There's a wire that doesn't belong there. And at 2:08 it's gone. The soldering of the outlet also has new traces only in that part.
Lowest.😞
yes...🤔🤔
A fraudster pre-crapping his fraud
Я бы за такую рестоврацию руки бы оторвал, и этим же паяльником придог бы!
🤔🤔...??
All that work and it's worth only $50 tops if you're lucky to find a buyer
yes..😇
Now I appreciate @MendItMark even more...
Thanks for your feedback
Did u connect 2 speakers to it,,,to b sure it sounded in both left and right channels?
Lucky u didn't do any further damage,,,from those fireworks earlier...
So those 30+ year old power supply caps just get dusted and go straight back in…
He first fries the power supply then fixes it… what about getting a variac?
yes...
Làm rất tốt. Cảm ơn anh
thank you..👌👌👌
One tip for your next project: Get yourself a current limiter....
yes
Пайка конечно жеееесть!
Да нормальный такой паяльник
that spark is fake ..Don't assume the audience is stupid..
That looked like acid flux plumbing solder.
I can't even...
That orange peel clear coat was a really stupid idea.
yes...If you have a better idea...
Thank you

Дружище,он хоть перчатки не надел.Бесят мастера,которые в перчатках радиоаппаратуру ремонтируют. Какой же кайф,когда ты не только глазами,но и руками прикасаешься к технике! И в добавок:-этот конь крайне херово обработал корпус.подтеки даже на видео очень хорошо видны.
I'll tell you what I bet that's a lot of work you're doing a good job
Chập cháy thế mà ko thấy bị xám khói chỗ nào nhỉ? Thật là vi diệu.kkkkk
Hay
The most RUBBISH repair I have ever sern !!!!!
Pieza por pieza
Fun video to watch, but clearly fake. Doubtful that that crusty machine ever worked again, & why is it blowing sparks, fire & smoke? Foil wrapped around the fuses? & why did you completely tear it down? Only the bottom cover needs to be removed to access the full main board, you even removed the power cord! Oh, you're just junking it out, & making a video for likes & subs, now I get it. Nice Work!
Bizarre but entertaining. I don’t even know how I ended up here since I normally don’t watch other people’s repair videos.
Committing fraud with the adverts [cash-cows] ~ how many advertisements was this video infested with?
Some people need to learn the difference between soldering and mig welding !?
