It is really a time consuming job when Matched pair transistors are mixed together. How to test and pairing of transistors? Nowadays, it seems there is no shop selling matched pair transistors.
its fake.... Like 99% of the foreign "amplifier repair" videos.... Some of them are faker than others.. Some, you can clearly see the brush marks, where they've brushed mud on to it, To make it look old and broken 🤣 Half of them dont even know how to use test equipment properly either... Most of the videos, then dont check resistance values etc on the multimeter.. They just have their multimeter set at incorrect settings, and make sure the needle moves, And think its good. 😂
Not a power engineer then. I've seen this and worse from electronics. The most spectacular was a 4 kW three phase 220v xenon arc lamp power supply. It forcibly detonated and launched purple and orange balls of plasma 50 feet away. Detonating mosfets and mosfet drivers can release showers of sparks and debris, as well as create a spectacular light show if the vaporized metal allows an arc to form. Purple/blue/red lightning all inside your PSU. That being said, this video is very obviously staged.
@@oldschool2546 Okay, it is good to see that you are keeping busy. A lot of people that watch these, would not know difference the different amp classes, IGfets, MosFETs, NPN PNP, voltage rails, et al.
if you're stupid enough to power up a unknown amplifier, Without using a Dim Bulb.... You shouldn't be anywhere near an amplifier....... Amplifier Repair 101: ALWAYS use a Dim Bulb for protection, If the amplifier is in unknown condition... This video just shows, You really shouldn't be touching electronics.....
Nice restoration job.
Beast of a powerhouses!
Beautiful 🌹✨

Parabéns amigo,o amplificador ficou novo outra vez, muito bom.👍🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷
Parabéns vc e um grande profissional
0:02 Two strings together?😂
Very nice job 🇹🇿🇹🇿💪💪
Beau travail !!
Super resiver veri good!
saludos cordiales sir que marca y model es el amplificador
Bahut aaci sarvising
nice repair techniques bro
Restaurado amplificador de áudio 😉
What is the value of changer components?
12-56 minute, what liquid is he using to clean the pcb?
YOU CAN SEARCH IN GOOGLE PCB CLEANING LIQUID
Everything is new in this amplifier. Stop the repair. It's fake news!!
It's not how it works my friend...certain things must be replace...unless you can fix transistor or resistor that similar size to an ant...
Muito bom!!!!!!!!!!!
A minha parte favorita é o início
просто так предохоанитель не летит же)думал поменяю пред и все заработает? неее друг так не работает-если пред сгорел то нужно искать причину!
ok na lodz
good vide
А искры были не плохие.😅
5w laser light ke repairnig video dalo
totalan.njeblug kabeh finale😂😂😂😂
sir tanong lang po yong diy ko na power amp bakit di pantay ang init ng mga power output may subrang init meron naman normal lang
TRANSISTOR PASIRA NA
😘😘😘
👍👍😮😮
Сначала сжег схему и вот ремонт😂
mau di jual GK boss

This amplifier is new. Why it's to repair?

@@RGD-Games I have missed those....what setting do you use on your FET VOM?
Nah... no electronics I have seen make such nice "new years sparks". And I am an electronic power engineer
And you build amplifiers too!

Actually have been developing audio amps 100-2kW, SMPS - trafo - class A/B - class D mono, stereo, 5.1

First problem, you turned it on:-)
我想和你联络可以吗..谢谢!

Check first before you on ...no ..experience guy would do what you are doing ...

Just making content for UA-cam …Not a informative video.. this is only a task of repair not a restoration

What did repair techs use before the bulb tester was found to be useful ?
Hgugkj❤guhhp
So fake 😂
Awful vid
Sir apka whatsappy no do plz
Nice restoration job.
