bPlease make sure to watch /bb59:05/bb * THE IMPORTANCE OF IMPEDANCE * This is the fundamental principle of all fault finding!/b Comment from : Learn Electronics Repair

Great tutorial! I liked both the schematics explanation on plain paper and the actual verify with the scope Comment from : Christian Musso

I don't know if you deliberately made mistakes or if you you just covered your blunders well Either way, they provided opportunities to explain what can go wrong when building a linear power supply (or any other circuit) and how to troubleshoot, diagnose and repair the faults, which is valuable information indeed! Thanks so much for this video, from which I have learned a great deal Comment from : Carl Gradolph

Absolutely the best explanation i've ever seen Comment from : Bri Kaf

Thankful for your efforts to teach us Comment from : Jጦር

Awesome tutorial! I loved the structure of starting with almost nothing, testing along with your observations and gradually building in complexity to the final product, great stuff!brA next step project that would be good to learn from is a simple amplifier, I get the gist of them but my understanding of how current and voltages apply at/through the base/emitter still needs work :)brThanks Rich 👍👍 Comment from : Mick Duprez

Just found your channel It is very interesting thanks Have you discussed the Isolated Test bench in another video, if not I would find that explanation informative Comment from : Gr eg

Thanks for a terrific video, Richard I've enjoyed all the ones I've watched so far A friend of mine in the computer club we both belong to (he's the president) had watched one of your ATX power supply repair videos and told me about it I'm also interested in all things audio as well Comment from : John Marchington

Tantalum cap in reverse we could have seen it flame up Comment from : David Hollfelder

Should have used a full-bridge rectifier across the two white wires and black would have been CT or common you would have had plenty of voltage in that case to use 7815 and 7915 the scope trace looked that way because you had no load on the diodes and they need a load to switch properly, the 1/10M loading of the scope probe often isn't enough brbrSteve Comment from : Tested to Destruction

I really really enjoyed this video Thousands thumbs up, Richard! Comment from : Mahsa Kashefi

Just found your channel, used to do instrument repairs for an electric company (NEEB), 500v I/R testers to 30kv I/R test sets to 60 Kv oil test sets and every thing in between, best job I ever had, still have an interest in electronics but don't get much practice these days You have re-ignite my passion Thank you Comment from : Martyn

Heya that is a nice way to make some project indeed Comment from : Dutch off grid homesteading

Thank you so much for all you do! Comment from : Jons Diagnostic

the led's on chargers don't light up till a battery is placed in them to join up the curcuit Comment from : Stef

Perhaps you should mention voltage and current transformers are generally rated in VA Comment from : Alan Richardson

I do like the way you explain things, please carry on your good work 👍👍👍😀 Comment from : Paul Muff

What country is this? It has the same plugs we have in South Africa I'm gonna guess australia simply because my stepdad has the exact same laugh He is from Australia Comment from : Will Smith

This kind of devices lights up when you put a batteri to charge Comment from : semployées doiveselavi

How to learn about electronic devices br1 Watch every video on this channel br2 Buy a multimeter and an isolation transformerbr3 Find broken stuff, take the lid off and start taking readings Comment from : LR Disco

Loads of info! Easy to follow! Great video! Comment from : Chadillac

A nice watchcheers Comment from : andymouse123

sorry but this smart meter so you do not have to switch every time you measure ac/cd ampere or volt or ohms thanks for the great videos Comment from : ak coord

I startet to watch this chnl from Sorin, but it's so hard to find LINEAR PS without protection can anyone advise me some of them ? Thanks in advance ! :) Comment from : COREL

excellent videos coming from your content :) Comment from : GDaddyD

A good source for a linear regulated power supply is one of the 'SOLA' type industrial power supplies In stock form they are available in various voltages from 5-24v DC in various amperage values The transformer outputs between 50-65v AC if you want to do your own regulation/rectification circuit Comment from : jordanch68

Are you open to recording some footage at the car boot sale as well? I find it interesting to look around virtually Comment from : James Collins

Great vid, highly informative Re ohms law, just cover the required value with your thumb ! Comment from : Conway Noel

i have a scope that has a problem just like yours it just sits taking up space i did find the problem its been so long but its not any thing big Comment from : Amber Smith

Maybe you could use the lower voltage part of the transformer as a single 5V supply instead of a plus and minus supply? Comment from : KB1UIF

Superb content Dickie Chapeau! Comment from : J Murph

Hi Richard great vid Can you tell me if the kaiweets km601 you reviewed has adequate resolution to work well with the £1 sort finder you built? Thanks Comment from : jonathan dyble

😎 👍 Comment from : bob fourjs

Love your videos no matter how long Comment from : HENRY BARTLETT

Perhaps a filament bulb was used because it was on the 240V AC side Comment from : Greg Reynolds

I love this channel! glad the algorithms recommended it Comment from : Kelvin Wekesa

Great vids! Your transformer diagram looked more like a step-up than a step-down, but I am just glad I can actually tell the difference! Comment from : jack william

@1:26 I was very surprised by how the FBR was drawn I thought it was drawn wrong or something but it is of course, correct I just never ever seen anyone draw a FBR as asymetrical like that It took me a good wile of thinking and redrawing to discover that you actually had NOT messed it up Good exercise for me Comment from : Nicklas Persson

You can use termal paste of CPU to see the chip numbers ( marks ) Is better than the alcohol 😜 Greatings from Portugal 🇵🇹🌟 Comment from : Henrique Ferreira

You should add a tip button to your videos Comment from : Adam Sheridan

Be careful not to over voltage or reverse feed tantalum capacitors They explode with fire They used to be all the rage, but today 99 of the time MLCC capacitors are smaller, better and safer Comment from : Cliff Matthews

This is one of the best channels on YouTube for learning electronic repair! Thank you for all of your efforts! Comment from : IT-SD Data Recovery

11:12 you can make a "KGB screwdriver" yourself by using a flat screwdriver, and use thin cutting wheel on the Dremel to make the gapbr12:51 That small incandescent light bulb can have 2 purposes, as a "charge" indicator, and also as a current limiter, because those small SMD resistors alone on the back can't limit the full current that the transformer wants to deliver to a flat battery Comment from : Bjorn V

No fuse, to protect transformer? Comment from : Joe Shmoe

Thank you for the lesson sir! Comment from : Vision

Educational, as always Not sure if you tested current, voltage etc without the dim bulb in circuit Probably makes little difference at these relatively low currents, but worth a check Comment from : ralph J

So far this is my favorite vid Really enjoyed this one Comment from : j s

Its to keep out the average muggle Same level of security that keeps average muggles out of operating systems It defeats and deters 90 percent Per your special screws comment Comment from : j s

you really need to make oscilloscope for repair tutorial Comment from : lodoviko

Cool Comment from : weerobot
