I have never seen anyone so comfortable and easy going with electronics like you.
You make it look so easy.
You have an enormous amount of experience with electronics.
Very professional!!!!!!!!!!!!!
I sure wish I could find an old 70s type ab - amplifier to have you rebuild. I go to goodwill all the time but the older amplifiers and receivers dont never make it to the public. Somewhere down the line an employee or shipping person always scarfes them up before they even make it to a store to be resold back to the public. It's a shame really.
I would love to have an older Pioneer, Sansui, or Marantz.

@Lloyd Stout Popierdolił ci się profesjonalizm z komercjalizmem. Gościu czuje się w tej profesji jak ryba w wodzie - ile na tym zarobi? - tylko on wie. Pierdole "fachowców", którzy diagnozę urządzenia zaczynają od wymiany płyty głównej, lub od sentencji "stary model", "nie ten typ" i oczekują zapłaty za taką diagnozę/naprawę.

Ага, я в школе также проверял
Сильный дядька, прозванивать транзисторы даже с выпаянными эммитерными резисторами, это надо уметь.... Синий светодиод на защите и зелёный на клипе - очень логично 😉

особенно про клип. клип - это же хорошо, громко - поэтому и зеленый
вот что ты придираешься???

Great to see you bring back old things and not in the land fill.
PS Keep up the great vids.
Excelente trabajo, quedó como nuevo, me gustó mucho.

I mean no offence to the other guy on your videos but it’s nice to see those familiar seasoned hands back again! You both are very skilled at what you do! Thank you 😊
This is the time period when amplifiers were built really good and solid. I have an old PV 1.3 k I recently rebuilt from the ground up took me about 2 weeks to rebuild it because of all the parts I had to order. And I love this amp.Weighs 100 lb though 😁✌️
This is not a Peavey, it's a Chinese knockoff.

Incredible effort and super skills! Thanks for posting.
Very good restoration.
A "Made in China Peavey" got properly restored in Vietnam, Love the guy
Sr tiene ud todo el conocimiento de el amplificador felicitaciones por sus manos mágicas
That’s crazy AWSOME!! It legit looks brand new!
Impressionante o nível de detalhes, parabéns!! 🇧🇷👏👏👌👍
o cara é ninja!!!!!!!
Hard working man, look at his fingers... Geat job!
I see his fingers and I see someone with disgusting dirty chewed nails.
Got to say, I didn't expect you to pull that one off ... Well done!
What a beast of an amp! Now to find speakers that can handle it.
Excellent repair, and clean up.
Struggling Parodox
... in the live sound business it's not hard to find speaker systems to handle major power like this. Quite often it's several speaker cabinets, which is why these amps are rated down to 2 ohms. (4 cabinets at 8 ohms each) Oh, and in professional use they are seldom driven to full power so likely run all day at 50% output.
Ждем на Авито, после профилактики... 👍✌🤘
Muy Bien, Gracias,
Bendiciones desde Medellin, Colombia.
Bueno muy bueno felicitaciones alos maestro que se dedican a este ofició que es real mente bueno
Молодец!
Man this technician dives into this amplifier like a true boss ain't afraid of nothing
LMAO TRUE THAT ! XDDD
Товарисч в начале ролика так уверенно снимает крышку усилителя и откусывает провода, что создается впечатление, у него этих усилителей в день по 5-10 штук...
Excelente trabalho,parabéns.
Exlent workman ship, well done, thank you for up loading in RUclips.
Love watching people that just snip the wires with no worry and crack on with the job because they know what they are doing,looks like he could do it with his eyes closed
3000 hours? At a rated temperature yes, at lower temps they last much longer. 3000 hours is only 125 days of continuous usage...
And when you look at the fine details... you'll see it is a hack job.
Unfortunately people delete their stupid answer when you correct them. Somebody told the large caps would only last 3000 hours...

Mr Electricity hands tell the story of how long and hard this gentleman worked for the vast knowledge he possess. He is an absolute pleasure to watch
Great restoration, another component saved from the landfill!
I like the music Mr Electricity listens to.........
That was a lot of work, and while I might question some of your techniques, you have a well working amplifier for the price of a couple of FETs and a lot of elbow grease. Very nice.
I agree.
I've always been aware that the over cautious methods of Amateur Electronics people are usually alien to the Professional repairers ethos of quick dodges to get a repair done as fast as possible, to avoid Customer dissatisfaction of time taken, possibly resulting in non payment for work done.
It happens in most areas of basic Engineering where repairs or servicing have a time-v-result conflict - some effective dodges sound like horror stories or criminal acts, but you'll be unaware!
Social Media vids featuring quick dodges with a working result are really just showing what fixers have always done - but previously out of sight of an unsuspecting customer.
It's never been my style, but people always moan about how long it takes to fix things "properly".
2SCXXXX and 2SAXXXX are power transistor not FET

I'm glad you did the right thing and showed us that it works because some of these guys make it look all pretty I turned it on and don't show us that it works nice job
It was working all the time even before restoration.
@@asdfghjkl1755 Obviously it wasn't working before restoration. There were two transistor not working he fixed them.
@@cpachen680 Oh sorry then I think i missed that part, you're right. Anyway it would be better to show DC output next time.
@@cpachen680
... Well, we see the LEDS lit & hear some music, but what & where is the source?
There's probably no subterfuge going on with the resto' eventually working, but if you look closely at the cable connectivity from the power amp to the 1U unit on top of the amp (which could be a line mixer/amp?) that set up doesn't seem workable.
It's probably a 'Serving Suggestion' illustration - we just have to believe in it......
Just like any commercial advertising of desirable & costly goods shown in the media,
where reality is low on the list .....
Inche poder mamalon !!!! Para quemar bocinas a todo volumen
Felicitaciones mi amigo !! Saludos desde Santa Cruz De La Sierra Bolivia !!
You removed all the main caps but did not test for leakage, I'm amazed that all were perfect, but if you did not test them you would never know. I am also amazed that no tests were made on the complete re working, no voltage, QI or anything, just put it all together and it worked!! it's a miracle.
I thought the same
Hahaha but good result.
yes it would work, but because the voltages arent tested you can not get it to sound anywhere near as good as it could be. I had a sony amp with a bad transistor though everything else appeared fine after rebuild so changed transistor was amazed the difference it made, it was about by about 2 volts but after swapping it reduced the audio output a little but made the unit so much more sensitive to audio the only problem was it then amplified noise allready present which was hardly noticeable before but the fidelity improvement was amazing.
👏👏👏👏 Muito bom👏👏👏👏
Anda sangat menguasai dibidang elektronik..memang sesuai dengan nama chanelnya mr.electronik
que bien buen trabajo amigo, ese amplificador vale la pena reconstruirlos son los mejores que peavey a fabricado, tipo A- valen lo que pesan y el poder es 100% watts puros
Amazing - went from looking like it was pulled from the bottom of the ocean to new. Excellent work, like a surgeon!
Yes, good work, but a surgeon would do a much better job of cleaning his hands.
Nice work!! Your hands and fingers show the depth of your experience. Peace
Muito bom garoto gostei do seu trabalho está de parabéns.joao Alves Cáceres mato grosso.
tehnisi yg superhebat sangat profesional mantaap
This really amazing 😉, I remember back in the day when in the USA 🇺🇸 in every single neighborhood there were people that used to do this kind of things for hobby, nowadays the only thing we have are a lot of looser sitting watching someone else videos and willing to thumb down and criticize the people that actually create and fix things with whatever resources they have available. We have become a society of criticism where nothing lately is being created, only a bunch of stubborns ,self centered with not desires or creativity, just waiting for the next Black Friday to get in line and spend time and money.
Well said.
There are some real whingers commenting.
I agree with your comment
Nowadays most are smds and you need a different set of tools to trouble shoot. No transformer nowadys..The working is different. Howevet old equipment like peAvey is easy to repair.
I also in service & repair line. You open up the amp...The componets are so tiny. There is no marking or the type on the smd device unless you have the schematic. Some manufacturer dont supply schematic. They ask you to send the amp back to them. .To me, it is ridiculous as it is half globe away of travel. The other solution is find which board is faulty and change that particular board. Problem arise there is only one big mother board and everything is in it. Change mother board cost us 2/3 price of amp. Better change a new one!. Out goes the amp to the dustbin!...
You have zero clue what you are talking about, even less than zero. This video shows how NOT to repair electronics by butchering a chinese knockoff amp (its not a Peavey at all) and create a DEATH TRAP. Maybe in 3rd world countries they dont care about safety but in Europe or US you'd get fined or jailed for such repair if it was for a customer.
There is a difference between repair and butchery, just for YT views.

I don't know why I'm drooling looking at the build of this amp.
John Morris
... for the same reason many of us drool. We're old enough to remember Mr Scott yelling, "We need more power captain!"
EXCELENTE !!! Gracias por compartir con nosotros.
great restore.......for me new caps is a must specially for old amplifiers
I wouldn't wish this amp on my worst enemy. :)))))
Why not?
Those caps are trashed. Sure they will pass a simple test with a VM but that’s no way to test a cap. Plus they can go at any minute at that age. This is like taking a 1970 car, hosing off the engine, putting in two new plugs and a set of wires, then spending $199 on the paint job. It might last years, it might not make it home, but it looked kinda nice.
Absolutely agree. The plaudits here are impressed but size isn't everything.
Very skilled with the 100watt soldering gun. It's easy to lift the foil off the circuit board with too much heat. Glad you remembered where all those wires went. I was lost.
You are great mechanic 👍👍

Wow this guys a pro what an excellent job im audiophile was very impressed so left compliment
Un verdadero poder de Audio que bien que lo restauró súper
--like new-- like a car with rolled back odometer and polished paint; all i saw was 2 transistor replacement,all the other 46 are still old,caps too; ( i would have done the same lol).
Many thanks for the video,never saw so many 10000 uF (#12 of them?) and 5200 and 1143 (48!!! alltogether) in one amp!!!
You don't need to change something that still works fine, doesn't matter if it's old...I have still working electrolytic capacitors (Elna) 45 years old in some japanese amp, I changed just few drained ones, but all others still work good
It would have cost about £160 for the caps and about £150 for the tansistors, you would not get your money back if you replaced all those. Also large electrolytic power caps rarely fail it's usually small ones in switching power supplies that fail due to the operating frequencies. If it ain't broke don't fix it.
So long as the replacement transistors are of spec or slightly better then its fine. If you have a bunch of different types tho, then it will always blow the weakest one first.
Jose, when we rebuild, we change all electrolytic caps and signal path better quality mkp.
Transiastors and reaistors if not burned never have problems
Looking to restore an 80's boombox. Is that something you would be able to do ? I am in NJ how far away are you ?
Congratulatios... Excelent!!!!
Good job love it thanks for sharing God Bless keep safe
Meu Deus fiquei impressionado, o cara abre um amplicador que pra mim não tinha recuperação, restaura cuidadosamente e do nada aparece como novo de fabrica. Voce é o cara mesmmo hein. Nota 1000 pra voce.
Trop top ton travail 🙄👍👏👊🇵🇫Bonne journée à vous et ta famille merci Tahiti Moorea.
Merci beaucoup Messieurs pour ta réalisation bravo encore 🇵🇫👍
Restaurant made vile, only appearance matters. This is what Chinese refreshed equipment looks like. The capacitors were removed, their capacity and Esr were not checked. No sleeper current set and some other remarks. If the amplifier is to work, there is no guarantee after such restoration. It looks nice and that's it.
I learned a lot about how not to do things :P
Vietnamese
I respect your work.
muy buen trabajo....te felicito...
Nice work! Although, it's a little bit doubtful to me, that where can they find such an abandoned amplifiers? This Peavey isn't cheap, so if I have this, I would repaired when it goes wrong, instead of scrap it...
Very efficient, fast, restoration - always good to see inside groovy classic gear that once meant business.
Interesting to see an Instant Heat solder Gun used, though the components look tough enough to take it.
Leaving some insulation when snipping wires as a colour-colour reconnection aid is a smart idea.
Am mystified by the final test bench connectivity - looks like spkr/XLR-phono out, into the unit on top?
I'd be inclined to first test a monster amps output into something more disposable than those cute speakers.
Overall, an entertaining mix of good practice & speedy no nonsense methods that get the job done efficiently.
My resto's & repairs are so pedantically OCD that I'd still be getting a notepad + pens ready to make diagrams of wire colours & connections by the time this chaps completed his restoration!
