[@thenflywjaz6917]

Very inspiring. I disassembled a dead classroom tape recorder / pa for a friend today. Since he'd already written it off, I decided there was nothing to lose by attempting to repair it. I poked around with a plastic straw and discovered the fault was a dry joint on the main amplifier board. Power light came back on, and the audio burst back to life. Once I'd removed the power amp module and flipped it over I discover two dry joints which I resoldered. Mark, you're an inspiration. Thank you very much.

[@leehazlewoodism]

I love it when it turns out to be straightforward. The first time I ever took the lid off something was when my CD player stopped playing and made some alarming noises. When I got inside, I realised there was a lump of ferrous debris stuck to one side of the magnetic CD clamp so the disc was fluttering up and down as it rotated. Removed it. Sorted. It really helped my confidence.

Very jealous of this guys shop. His equipment is quite impressive.

[@dvohwinkel]

Mark, I feel that you undervalue what you bring to your videos and your repairs. You are an artist. We have watched you redo the windings of multiple motors, remake knobs, make pcb traces the OLD school way, etc.. I think your new venture will be HUGELY successful because you are a joy to watch and you have such a relaxing way of teaching/explaining.

[@whatcher8151]

Shut up. 😅

[@noobdernoobder6707]

It is the small 'inconveniences' in between he fixes in seconds that often would get me stuck for hours in the process to find a somewhat proper solution for it. Such a joy and sometimes even epiphany to be able to peek over his shoulders watching him do his 'simple' work.

[@HannekeStorm]

Mark, i'am in on this! I'm a autodidact technician with diy audio building experience. Worked for a amplifier company here in my city. And worked for 20 years as a sound engineer. But first the money goos to vacation. Hope to join in later on!

[@andrewpoxon4528]

I've only just stumbled on your videos and it HAS reignited my interest in this stuff. I'm 68 so it's never too late.

[@kleverich]

I'm impressed by Mark's repairs, and as he mentions the key is having an understanding of the functional blocks and tracing down what is and what is not working. His real skill is being able to identify and isolate the different functional blocks.

During Mark's intro I was waiting and hoping he would say the No.1 step was to 'replicate the customers fault'........and he did. Soooo important!

[@leehazlewoodism]

The frustrating thing is when the item arrives and there's no fault. I call this the "magic aura effect", when something works within my presence but reverts to faulty as soon as it gets home.

[@stevefoudray487]

We use a pre burn bench for that purpose.

[@gasgas2689]

There is a car repair channel where he gets cars that have already failed to be repaired by other garages. The very first thing he does is to verify the customers fault description.

[@TheElectronicDilettante]

Preach on Sir. There are so many channels that try to “teach “ diagnostics and just make the process more difficult to grasp. I’m glad someone finally said something . I was actually just blocked from a channel for , respectfully, giving my opinion, backed with documentation and other references. It was the opposite of appreciated. My biggest gripe was , verify the complaint. Simple. Second, have all the components of the system to be repaired. If you have a battery charger that only charges a specific tool battery. Sure, you might be able to muddle through and get lucky. But you won’t really know how the battery charger has failed if you don’t have the battery it charges. I saw one that tore into the board because the LED didn’t illuminate. Having about 12 of those chargers, and had I not been blocked , I would’ve shared that the LEDs always fail so you have to start there before anything. Thanks for your video.

[@y2ksw1]

[@christopherking5320]

Love watching your Online Electronic repairs show. You also show great knowledge with mechanical workings too. I did an apprenticeship as a radio/tv tradesman back in the early 1970's era, in Australia. I owned my own TV/White good sales repair service for 25 years. Started my own business around 1985 and did my apprenticeship starting in the black and white tv days, through to the colour tv days in 1976 in Australia and furthered my Technical achievements by doing night school when the CD player came into sales, to repair them too. Also, Microwave ovens and other electrical/electronic goods too. Yes, we even changed over a colour TV picture tube when a TV had lost the emission of one of the RGB guns and couldn't be boosted/rejuvenatedOH yes, I remember quite vividly getting Zapped as I forgot to discharge the tube from the Aqua-dag to the Ultor one day, nearly dropped it, but one mounting bolt saved the day!!!......Seen you get Zapped with a H/V capacitor too, not good. Thanks again for your great show and I love watching you perform your great and successful repairs. Regards, Chris.

[@Barbarapape]

Having recently retired after 53 years repairing consumer electronics at last i can pick and chose which jobs to accept and not having to worry about ensuring every one of them results in a profit takes away the stress that can make this line of work a bit daunting. I was lucky in that i attended tech college for the theory and worked full time learning the skills to find faults to component level without replacing every component on the board, only to find it it was only a hairline crack in the print. Good luck to anyone taking up this rewarding career even if only as hobby, it can earn you a nice level of income. Mark is one of the best you will find, stick with him as he shows that it is not a dark art.

[@fretlessfender]

[@JCWise-sf9ww]

"Mend it Mark", I really love your electronics repair channel. At 73 years old I still enjoy repairing electronics especially the older vintage radios and equipment and seeing how others fix things. Now that you pointed out the three step process for repairing any electronics device, I have learned years ago to find the fault and what's causing it and then replace or fix what is causing the fault. Simple. Thought it was a waste to replace a lot of parts needlessly. Only exception is replacing most all paper wax capacitors and electrolytics in very old radios.

[@johnwellbelove148]

Watching your videos has re-sparked my interest in electronics again. I used to do the whole deal; design the circuit, hand lay out the PCB with tape, get prototype boards made, populate and test them, and for the digital circuits, write the software to control them. I spent some time in the 1980s and 90s designing my own effects boxes, and mini-mixers for our band. Gradually, over the years, I move more and more over to a software role and rarely picked up a soldering iron. After watching some of your videos I've rummaged around in my old electronics draw and dug out some of my experimental effects units with a view to fixing and upgrading them. I may even revise my old RIAA pre-amp!

[@SassyXR6007]

I don't know if you'll read this Mark but I've been right into electronics since i was 8, I'm now 46 and my obsession has never stopped, it does at times though get put aside.

Mark is spot on with his process. I’ve been doing something similar for years . And not just for electronics. It works for ANYTHING! What’s the problem ? How does it work ? Find it , fix it . Done . I know it’s sounds to easy , but a little practice and you would be amazed at what you can accomplish.

Thanks Mark, appreciate your commitment to sustainability and taking the initiative to repair rather than replace your electronics.

[@paulchasteauneuf2098]

Hi Mark, just repaired an old Garrard turn table, mainly because it’s mostly mechanical. The main issue was old grease that had gone sticky preventing free movement of some delicate parts, which I learnt about on your channel. Thanks for all the great tips and advice 👍👍👍

[@jasonsomerville2504]

Once fault symptoms identified, Half split method was what I applied when I did this for a living...especially when diagrams aren't around. consider anything that works hard, or fast, or hot....as likely culprits, I.e. PSU, oscillators, high voltage components, and mechanical...so I wholeheartedly agree, good advice Mark 👍

[@LukeZalvino]

I can certainly diagnose like 75% of simple consumer products but mark has a much larger knowledge of how transistors and amplifiers work which most people won't. I think transistors will be the roadblock for many people like myself who struggle to pinpoint them as the problem, test them out of circuit and such. ICs as well

[@leehazlewoodism]

Definitely ICs because of all the pins. At least transistors only have three.

[@johncunningham5435]

I started dabbling in electronics when I was 15, from tube to current surface mount repairs. Now! at the tender age of 72 I still enjoy the challenge, especially vintage equipment. Like you I a massed a lot of test equipment over the years as technology advanced. Mark! your video's are most informative and educational, (I love your sense of humour).

[@JurassicJungle]

Love watching some of your repairs Mark. I trained in avionics many years ago and did 3rd line repair for a couple of years. I developed some reasobale skills but the job was going nowhere. I then got a job doing field service for a company that gave us a massive kit of parts to swap out, sadly these kits were usually missing the parts required as they were the ones that failed all the time. I ended up using my box of hobby components to do component level repair in the field once I knew the regular common faults. My frustrations with the compnay sending me out 2 weeks late for a next day call with no spares meant I didn't stick at it and moved into IT which was very rewarding but I still miss working on equipment and understanding how it works.

[@adrianmoore4160]

Well done Mark. I think the proper college training died out in the 1990's. I did City and Guilds 224 Electronic Servicing and college although I did the measurement and control leg of the course instead of TV & Radio. One thing I will say with repairing vintage kit is if it arrived in the post always take the lid off and have a good butchers to make sure there's no internal damage prior to applying power. We were taught at college to split diagnosis in three 1 look at the output, 2 look at the input then 3 look in the middle. You can narrow down your search for the fault to the first part of the circuit or the last part. My first repair was called poke 'n' hope by one of my colleagues.

There is also another group of people who enjoy watching your vids. That is retired techs who enjoy watching other people work. I, myself, am pleased you still use a CRT 'scope. We also understand the great sense of satisfaction in effecting a repair, particularly if it has been passed on from someone who wasn't so successful with it.

[@tim9778]

Hi Mark. Yes! All steps very important, but perhaps step 1 the most. I was taught re-produce the fault( to make sure it’s not just user error), and it will help you narrow down where the fault is. The thing to remember about vintage gear is it is generally easier to repair as the technology is older, meaning it’s more like to be repairable,generally one doesn’t need sophisticated test equipment and there’s often service information available. Quite often someone else will have repaired an identical item which can help. The best way of all to learn though is to do it. Practice on stuff that doesn’t matter. Old stuff that people have thrown away. Get stuff cheap at car boot sales. If you don’t fix it it doesn’t matter, you will have still learned( and you can break the item for parts. Gradually you will fix stuff, and your confidence and experience will grow. It’s also amazing how many faults are really simple.

[@MikeGervasi]

Great idea, mate. You've helped me on specific items which was huge. We learned The 6 Step Troubleshooting Method in the military. I think the step that should be in your 3 step method is "Half Splitting" Instead of say, signal tracing end to end, spilt it in half and see if it's there. That will point you in the right direction, cutting down diagnosis time.

[@wirdy1]

Yes. The military taught me the half-split method too; it's a great system. As well as the one-hand-in-your-pocket when probing HT supplies!

Really enjoy the videos & I'm lucky to have served a technical apprenticeship in the military, which had some excellent training. 1st check is always to verify the power supply, then fault finding by the half-split methodology. Has done me well for the past 40+ yrs 😊.

The 200 pound repair on average is a bargain, when you consider the equipment rack Mark has and skills he has acquired. Then you get a top notch job on top. I wanted to say thanks for explaining how an opamp works and that it introduces noise and the basics of parallel opamps to sum / cancel the noise. I'd never understood that and you explained it in about 1 minute! That was on the master reference series pre-amp repair you did.

[@MrMersh-ts7jl]

This is the same exact approach that I take when diagnosing vehicles. Whether it's the electrical or the electronic side, or the mechanical side. Step number one is always always always, verify customer concern. Within those three words also includes gathering as much information and being able to understand and interpret what the customer or owner is trying to tell you. Learning to speak with and understand your customer and their concern / complaint is a skill unto itself. Step number one: verify customers concern. Thank you so much for what you're offering. Not quite sure I got the quid but I'm glad that there are people out there offering this. Mr Carlson offers something similar however I imagined that like two different teachers face to face, one could gather a multitude of skills and knowledge from several sources. I absolutely love your videos, love your demeanor, and love that you share with us something that excites you.

[@whatcher8151]

Dirt, grease, rust in your eyes, dirty tools if ya can even get in to work on those sardine cans. Is the point. Like Mark ya gotta have tools, investment capital to move and forge ahead. It comes with a cost but if ya like it, do it. You could just make preamps at only eight per year and make 250 grand but what the hay. You'll understand that one if you watch the latest repair on that preamp.

[@daShare]

Many items that come in to me would have been simple jobs originally, but having to sort through the mess after they tried to fix themselves adds time and money to the repair. Other times it's due to people replacing a blown fuse and trying again multiple times, usually with much higher rated fuses! I can only hope that people who take Mark's course learn the valuable lesson of not blindly charging in without understanding what the real issue is. Not everyone has the right mindset for troubleshooting.

Hi Mark. Can I first say that I have been an electronics repair man all my working life, 45 years plus, and you are quite possibly the best all round technician I have ever seen. However, please don't bother with any more videos like this, your normal content is what we all keep subscribed for. It's worth mentioning for anyone thinking of taking it up that the £200 per repair has got to depend on where you are. I am in West Yorkshire, and many people here live in some sort of time warp where they still expect an amplifier to get repaired for £50 or less. This is why I don't really bother doing the job any more apart from a few bits of vintage valve equipment of my own that are destined to sell on Ebay, or valve guitar amplifiers that belong to musicians I have known for years.

I've always enjoyed your channel, Mark. I was trained in electronics and did the college years ago! So I don't need to sign up myself, but I do wish you all the best. Only comment: Someone working on an old vintage valve radio shouldn't just plug it in and see if it works, (as you know) the bad caps in it could mean damaging hard-to-replace bits like the output transformer or output valve, etc. Usually OK if you use a dim-bulb, though.

[@ctrlzyx2]

Having done a few vintage repairs successfully, i would suggest an important step is omitted. That would be googling the specific model and problem. Say you have a pioneer sx-780 with left channel distortion. A quick search of the phrase "sx-780 channel distortion" is very likely to turn up a bunch of threads addressing that exact problem. Skim through those and you will often see a pattern emerge which guides diagnosis and saves time. I agree with the idea of a systematic approach. But places like diyaudio are loaded with threads on vintage devices and their common problems. Carry on, Mark, and good luck with the new course.

[@dublegi-hr8kq]

I think most people watch channels like yours because they want to learn something. Not just to repair appliance x. There are many videos targeted at that audience and they are short and to the point, not much explanation, just a "colour by numbers" set of instructions in a five minute video. That is not what your audience is here for. Channels like yours capture people like me, who have no formal education in electronics but want to learn. Long videos are not a problem for us (on the contrary). Theory is not a problem (on the contrary). I would like to see more of that. There are some channels like that too, (see professor Fiore for instance, and Mr Carlson of course) but not always attacking things in a cohesive and consistent manner. There is a lot to learn and I myself feel I have made significant progress, watching and doing, but there is some way to go. One suggestion for others like me, perhaps if you start from scratch, start with vacuum tubes, even if only theoretically. I find those much more intuitive than semiconductors. Once the basic topologies are understood, it will make your life easier to follow a solid state diagram (start with simple things, of course). Good luck with your course and hope to see more of you around here. You are fun to watch (and that is an important part of your channel's success).

"... some old electronics you've got lying around ...". Nope, not me. No sir. I don't have a dozen or more various old audio components in the house, waiting for the day when I get motivated enough to learn how to get them fully functional. Don't know who that would be, but it ain't me! But this new program you're offering sure sounds interesting. I mean, just for the educational value. Not because I'd use what I learn to fix hose old electronics I've got lying around. Because I don't! :)

This a really cool video. Enjoyed it a lot. Your repair videos are one of the very best here on KZbin. Keep up the good work!

[@michaeloconnor7849]

Good morning i have watched several of your videos and always found them very interesting and educational. I was going to watch your 25 grand pre amp repair as we all hope to find a golden nugget at a boot fair or similar. This morning KZbin sends my my usual Louis rossman video and I could barely believe what I was watching suffice to say i would take him up on his offer as Mr Evans will be beginning to regret his decision to go after you with a copyright strike. All the best and be assured many more people feel the same way. Just as an aside i went on their website and they are charging 60 quid a poo for a binding post that you the customer have to apply nail varnish to to prevent oxidation yet the wire is attached with a grubscrew which if memory serves don't come supplied with their own vacuum field. He should be playing Barbara Streisand on heavy rotation whilst watching his sales plummet.

Very nice tips. Always love to see and follow your repairs

I would love to learn to have a better understanding of electronics to the point where I could attempt at least some basic repairs, but I only have the most limited knowledge. I've been thinking about joining up to your course to learn something new, but I'm mindful of getting left behind quickly, especially as there will be so many people who will join the course and will be streets ahead in their understanding. It makes me think about school in the '70s and how easily I got left behind in some subjects there. I watch your videos in awe of how you repair and understand the intricacies of your trade. I guess what I am saying is Mark, is your training course suitable for people like me who are on the bottom rung of the ladder?

[@cliffordwells2793]

Wow.. you could have read my mind as well.. exactly my dilemma. I've been trying to find a hands on guy to get through all the basic steps as well. I forget so much just reading and watching, but retain more 80% by hands on. Sound like you??

One heck of a sales pitch! If you have a notion to effect repairs, go for it! Working in a industrial environment we hire really good graduates, the thing we struggle with is not the technical skills and qualifications, its nurturing their sense of curiosity, when something keels over we need an engineer who asks the question why and is willing to play with the equipment to reach the problems solution! So if I were to add anything to your pitch…it would be nurturing a curiosity and asking why XYZ failed.

You are right, I started taking things apart to learn how they work as long as I remember.I repair for most industrial and maritime PCBs besides measurement and calibration gear commercially B2B for 15 years. If you only do it to earn money you will stop very quick. There are no easy shortcuts. The things most important for me are: 1) Good knowledge of electronics and for most the drive to fix things/solve problems. For most if you repair stuff without schematics and when there are no you tube videos or forums about the thing in front of you. Most times you are on your own. If you repair consumer stuff it all gets different and a lot more easy. Sound knowledge helps a lot but most times you can find the problem on you tube or a forum and just blind replace parts. But without sound knowledge you will not be able to repair it if that does not solve it. I'm self thought, I spend years of study, every day several hours reading books, experimenting, designing + building for real and in a sim (the best way to get problem solving skills). 2) A real good solder/desolder station because I need to remove a lot of components to be able to test them. I use 2 pace stations with each 3 handpieces and a good hot air station. With cheap crappy Chinese stuff you will often cause more damage (they are not all crap but it is a gamble to find the not crappy ones) To find info is hard because many reviewers only have experience with other crappy gear used on cardboard consumer electronic pcbs. Bang for buck is not gonna help you when doing difficult desolder jobs on pcbs with massive "cooling capabilities" and if you damage the PCB you have to tell your customer you damaged his pcb because you only use crappy tools. 3) Test gear, I can not work (My types of repairs being PCBs from machines/ships) without a Scope, a real good LCR meter, fast DMM, DC lab supply, DC load, AC lab psu and a lot of special component testers. ranging from simple semi-conductor testers to a curvetracer and a SMU. I also have several IC testers, one of them I made myself and is the idea of a tube tester using 16 twelf position switches. I also have a fancy breadboard with build in PSU, function gen, Leds, debounced switches etc. I take a datasheet, desingn a test circuit, test the part and solder it back. For testgear and calibration gear I have several calibrators, standards and a K7510. I also use a lot of current measuring things because current often tells you more then voltage. For incidental consumer stuff I only need a scope, LCR meter , function generator and DMM. I prefer a scope above a DMM. There are things you can not compensate with knowledge alone. 4) Patience and the will to not give up, even if that means you have to dismantle the whole damn thing for the 6th time, do not let the defect electronics win ! My steps: - test the thing to see what is wrong - good optical inspection of the inside - check the PSU for ripple and voltage - what ever is needed to go on like connecting a FG to the input of an amp and follow the signal with a scope.

@@pa4tim I completely agree. I work in the pump industry and the lads that show an interest are the ones that finish up in demand. Everyday should be a school day.

​@@adrianmoore4160'every day is a school day' never a truer sentence. Life is satisfying if you can learn something new every single day.

Caro Mark, mi piacerebbe davvero iscrivermi al tuo corso , il tuo modo di riparare le cose è veramente fantastico , purtroppo non padroneggio bene l’inglese e quindi ti seguo con le traduzioni ( non sempre precise) per questo motivo sono costretto a seguirti semplicemente sul canale libero , comunque i tuoi video mi hanno insegnato molto. Grazie .
