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.
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 see his fingers and I see someone with disgusting dirty chewed nails.
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...

Re the criticism about cutting cables. Despite popular opinion this was common practice in the service industry where Large scale disassembly was required. The reason- clear identification for re-assembly, a good aid even when you have a circuit diagram (schematic). I applaud this guy making most of the limited tools available to him.
To be very honest with you, I really admire you from afar. You are technically a gem!!! I wish I repair whatever item that comes my way. You are too clever.
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.

A "Made in China Peavey" got properly restored in Vietnam, Love the guy
Ampli này quá khủng 👍👍
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...
Hands of a man that works for living.
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.
@@puciohenzap891 I see it's a fake got it thanks for the info 😁
Kita hadir lagi nonton sobat.👍👍👍
Peavey lasting for lifetime under normal uses. Because they are made in the USA. Not made in China. They are solid states. America made good things for the world dying to have long ago, before made in China. Those high quality capacitors made in the USA. Transistors and high voltages resistors are totally reliable. Look like I need to send him a Weller digital solder iron. Those two transformers are the best of the best. I have Peavey tour system long ago in the 1980s, they just never stop. The same with QSC, CrestAudio, etc.
I am sure Peavey president will give him a big contract with extra bonus for revitalizing Peavey reputations to the world. Now this one ready to sale for $400. Great job. Got thumb up and five stars.
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

Parabéns pelo lindo trabalho. Muito bom e muito eficiente. Bom profissional.
What a marvellous work and valves and transistors have sound.much more fidelity than any.modern.gadgets.
Yea, I remember (not fondly!) having to "drag" our Peavy amp rack around every night after the gig was over (let alone having to drag it in...). Our amp rack was 4 CS-1000's along with the top set of main's and the stage monitors controllers. I bet that damn thing as an entire unit weighed in well over 300+ pounds. And we still had to set up all the other things - the main 24 ch mixer, the set of main speaker (s) (4 total speakers PER side), the 100' snake, the other 2 smaller cases that held all the effects and the other case with the cd-player and cassette, then all the other cables (all the speaker cables and all the other asst. smaller cables, then there was ALL the mic stands with all those mic's of different types (some 20 I think)... Yea, doing LIVE SOUND "was" great WHILE we doing all the ACTUAL events (bands etc.)... BUT - - - the ACTUAL DRAGGING IN AND OUT WAS MURDER ON US, and most of the time it was ONLY just the TWO of us!!! And a FEW times is was ONLY ONE OF US... Don't ask how we did it back then, I'll let my 4 SURGERIES LATER DO ALL THE TALKING!!! (and we did that for some 7 years until the local music scene changed from live bands to the DJ era... Live Music I think missed out after that time happened in the mid 90's. We as a whole did an AWESOME thing being the UNSUNG heroes of the day. R.I.P. to all Live Sound Guys & GALS WORLD WIDE...

great restore.......for me new caps is a must specially for old amplifiers
Man this technician dives into this amplifier like a true boss ain't afraid of nothing

Nice work!! Your hands and fingers show the depth of your experience. Peace
Very good job and restoration of amplipier
thank you bro I was having a really bad day this inspired me
profissa é outro nível parabéns ficou show
Amazing how that dust was placed back in the base of the freshly painted amp during re-assembly!
muy buen trabajo....te felicito...
Excellent workmanship sir.
soldering a transistor with a soldering gun is like vascular surgery with hedge trimmers
Thats what I thought - but it seems fast & effective in this context though.
Maybe the devices are too robust to suffer from high & instant direct heat?
Instant Heat Solder Guns were always frowned upon as 'amateur plumbing' gear
in the UK Electronics media of my youth, with low-medium heat precision irons the only acceptable path to kit building Nirvarna. (which made soldering to tin shields impossible)
Actually a larger soldering iron heats up the part quicker and shorter. That way the heat strain is less on the part. On most production lines they use a 75w iron for these parts.

GREAT VIDEO MAN GOT TO WATCH MORE
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.
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.
Excellent restoration!
Thank you. Greetings from Brasil.
Incredible effort and super skills! Thanks for posting.
Very good restoration.
ทำงานละเอียดดีมาก..verlygood
Merci je bcp aime sa cette experience tres bien
Exlent workman ship, well done, thank you for up loading in UA-cam.
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.
Muito bom garoto gostei do seu trabalho está de parabéns.joao Alves Cáceres mato grosso.
Suggestion: Buy yourself a cap-tester. They are not that expensive anymore, and you can do much better and more thorough testing (like CSR) than just a good/bad evaluation. It will be worth the investment.
Wow look at the size of the transformers, crude solder joints, This is when they use to make things to last
Impressionante o nível de detalhes, parabéns!! 🇧🇷👏👏👌👍
o cara é ninja!!!!!!!
Freshin it up get another thirty or forty years of service , awsome
toàn là c5200 a 1934 hàng tháo máy thì quá sịn sò
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...

I like I had one now my son has it. It's the best Amp ever made.
Wow, you are a great engineer
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 .....
молодец мастер хорошая работа.Ставлю лайк
use protective equipments. Super job!
Конденсаторы лучше не так проверять. Есть специальные тестеры.
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

you should measure each voltage at collector's transistors to checked if it's paired after remplacing them. it help in stability and reliability.
