So I’m running a 3-part LIVE workshop that takes us on…
A Time Travel Through Vintage Electronics.
We’ll rewind the clock, dive into the tech of the times…
(and study the very history of how things were broken and repaired has evolved)
The workshop is coming soon, but if you're reading this then you're in luck (or not)...
And there's still time for you to sign up using the link below:

The workshop dates are mentioned in the link above too.

Mark takes on an abandoned repair of a broken 5000 watt PA amplifier - a CROWN XLS5000, (same as the Phonic XP5000). Its in a sorry state, and has multiple problems. A bit of guess work required, and some new parts making. Does it all work out okay?

When you said you would have to do the knobs, and I saw the amount of on-top effort, my jaw dropped. Best electronics repair channel on YT.
Nice chap: check, decent editing: check, best repair channel? Barely an also-ran. Still good to see all this 1960-80s tech. But I would question Mark's knowledge of the finer points of design.
💯 agree with you.
@@marcdraco2189 You dirt
My favorite electronic repair channel and so much more. Thank you Mark you are an inspirational and talented chap.
I concur.
Ditto!
Very skilled😊
Вне всяких сомнений
The knobs were the icing on the cake. Great job!
I just love this guys work. Everything he does is primo.
The white spots are hard to do though ;) hehe But seriously this guy does it all! Amazing skills!
True art
I love this channel! I had an old home Monster Power home Theater amp that refused to power up. I sent it to an electronics repair shop a couple states over they had it for three months and basically said they couldn’t fix it because parts are no longer available. I have no doubt that Mark could’ve fixed this amp. Wish I still had it I would pay to ship it over to England just to see it on a video. subscribed!
@@stevevanrusselt4739 why would you bring that d. g3/nr@te to the comment section of a mark's video?
Mark - you are my hero in this age of throw away out of date technology. I have always enjoyed taking things apart to see how they work, and I am fascinated by your detective - like scientific approach to mending just about anything!
I want to see the bench power supply repair now 😅
As a retired electronic technician of many years (music stores, etc), I thoroughly enjoy your videos. Like you, I had to employ a wide variety of skills to cope with the abuse that some equipment had to put up with from life on the road - the absolute worst was a power amp used in a rodeo p.a., not only was it beat up, it stank!
BUT, I must say, your skills (and your shop) are the very best by far!
I am very impressed and envious.
The clear difference between someone who takes pride in their work, verses a cow boy.
Weldone Mark! Love the attention to detail.
I appologize, I've spent some time thinking on your comment but I can't seem to figure it out. I don't understand the reference verses a cow boy. I'm not the brightest again I am sorry would you mind explaining it to me?
@@truth3899 come from a reference of a 'cowboy builder' (longman dictionary)
@@MsNIKITA ahh gotcha thanks kindly
Insane repair, your skills are amazing.
Crown International was started by a broadcast engineer and ham radio operator by the name of Clarence Moore (W9LZX). Clarence got his start in short-wave broadcasting in the high mountains of Quito Ecuador at radio station HCJB. In the 1970's when Clarence was back in the U.S., I was fortunate enough to talk to him on the ham bands as a kid in my late teens. He was the inventor of the Cubical Quad antenna, and I just so happened to have one. Naturally, our conversation drifted to antennas, and he was delighted to hear that mine was a Quad. He was a vast book of knowledge, but at the time I had no idea that he was the guy who'd invented the antenna to combat coronal discharge in the rare atmosphere of HCJB's antenna site in the mountains of Pifo Ecuador. It wasn't until he had cleared off of the frequency that we were talking on, that another ham told me who he was. I was a lucky teenager to work that father of the Quad and later the owner of Crown International. RIP, Clarence. de W4ABC...
Yeah them crown amps are a thing of marvel! If I ever have the choice of any amp vs crown, I always go crown as their reliability is unparalleled imo. Cool to have some backstory to the original owner/inventor of crown amps! ta.
HCJB - the call letters translated to Heralding Christ Jesus Blessings. I had a QSL card from them when I was a teenager SWL enthusiast.
Hi Mark, I'm a mech engineer (and previous trade qualified boilermaker/welder) who is about to start a degree in Elec engineering. I've been mad keen on electronics and audio since I was a kid, and I'd like to say I'm blown away by your channel. Your dedication to repairing things most would deem unrepairable gives me some hope for the future. Your videos have also helped me a lot with repairs I have undertaken.
Cheers from Australia.
Good for you!
Already looking forward to a power supply fix video! :)
I don’t understand electronics at all Mark but I find your videos fascinating and entertaining. Your skills and attention to detail are a credit to you. Thank you.
Likewise, it's fascinating.
It is an absolute pleasure to watch a man who really knows what he's doing, AND, has the right kit. Most repair channels on YT give me high blood pressure! Always entertaining too. Thanks Mark
Well the saying goes 'You can't turn a Sows Ear into a Silk Purse' but certainly have with this one. Well done, a brilliant transformation 😊 👍
I like that every stage of the repair comes with a little chortle!
It is a true pleasure to watch a man who is modest and really knows what he’s doing.
And who chuckles a lot, just to add to the cheery nature of this channel. 🙂
You are such a cool person with a wealth ok knowledge that most people don't have these days and great sense of humor
You are brave Mark, my heart sinks when taking on previously repaired gear.
You can spend hours correcting their bodges.
My heat sinks.
wanna say that I thought the repairing abuse this had made me think that there was much more damage @@vfrbore1728
@@vfrbore1728 No, your heat rises.. What are you thinking?
Great job very professional and time consuming locating the parts, l bet your customer was over the moon with that quality repair.
It needed putting straight. And you surely did. Thanks Mark for what I think is one of your best videos. Nothing better to start a leisurely weekend. Pure joy to watch. 😊
The amount of care taken in fixing someone else's mess...
Is remarkable and commendable.
Thanks for a great video 👍
Mark, the happiest repairman in the web! 😄
Honestly, your greatest asset is your patience. ALso that nothing seems to get to you. THe fact that you can fabricate gives you a huge advantage on repairs.
I am so impressed in what you able to do. It’s a shame you don’t have more subscribers so I will share what I watch with some of my friends who are also interested. Good work😊
Watching Mark mending things make me smile. His repair videos are gems!
Thank you Mark!❤😊
With all the repair channels on CZcams these days, there are levels. This guy is absolute top-tier. My only complaint is I want more content Mark !!
And every time I watch you getting that shock in the intro I laugh so hard...I always skip back so I can watch it again. It sums the guy up, and he doesn't try to hide it...everyone working on electronics will, at some point, get a belt !
The shock never ceases to amuse 🤣
I like how you just giggle at the different kinds of fasteners, instead of getting frustrated that someone put a bunch of random screws in
Amazing what you do. Attention to detail that is Mend it Mark. Enjoy watching your work. 👍💪💪🇩🇰
And this is why I don't work on stuff other people have been inside trying to fix 😅 Spend more time fixing the other person's idiocy than the actual original problem.. Good work as always Mark 👌🏻
When other people have worked on it I strip it down entirely and start from scratch and wise to as working with valve equipment can deliver some nasty surprises!
@@ianforfun1 I always ask the owner if anyone else has worked on it if they say someone else has looked at it and tried to fix it I usually decline to take it on, one guy lied to me after he sent it, I made him come collect it, if he wants to waste my time I'll waste his 😂
Really impressive work! And the surprise fabrication at the end was such a cool bonus. Bravo.
well done for taking this on...lives to shout another day.
Brave lad our Young Mark! Especially when someone has been in there before and bodged and given up!! Good man!
You are incredible! What a masterpiece!
I was a certified electronics technician back in the 80s and 90s. Our shop wouldn't have touched this due to the previous "work" (aka "butchering") done on it.
Your skillset and your tools are like a technical arsenal on steroids!
I thoroughly enjoy watching you work.
YOU GO GUY!
j'ai découvert ce Monsieur super outillé en matière électronique avec des appareils de mesure à foison !!et plus ces ateliers ,cette personne s'est tout faire ,et à l'air super compétent !!je ne me lasse pas de regarder !très intéressant ! cela donne des idées, moi meme à mon niveau pratique l'électronique !
46 minutes of bliss,great work Mark..excellent repair..well done Mark.
The rivets on the pots is a great idea 😎 Certainly one to file away in my brain somewhere.
ONCE AGAIN MARK YOU HAVE NAILED IT ........YOUR AN ABSOLUTE ELECTRONICS GENIUS WELL DONE TO YOU SIR
Once again easy to understand. and easy on the eye. Brilliant just want more please?
One of a kind Electronic channel. I love your channel Mark. Your knowledge and skills, your tools, gadgets and instruments marriage into one precise excellent repair. All the best ! Your channel is rapidly growing. Keep it up. Looking forward to your next repair videos.🙏👌❤
I'm not a fan of Crown amps and not a fan of the XLS series. But it broke my heart to see someone had abused this unit so badly. So happy to see it under your very capable hands! I remember playing with a JBL MPX 1200 (it was a rebadged QSC mx) and when I saw the dual layer, the massive transformers and the spaghetti of wires I decided I didn't want to touch it!
That JBL/QSC was still a superior amp to ANY of the Crown line. What was wrong with that amp you "played with" that made you not want to touch it? Did you really think that what you saw in that amp was worse than the hodgepodge in this Crown boat anchor? Even QSC's Series 3 (The modular ones) which weren't the greatest, were FAR more reliable and stable than Crown. I owned 5 of those modular QSCs and the only issue I had was a certain set of power resistors used to eventually melt the solder connections in the one channel where the module was mounted upside down. A reflow with good grade rosin core fixed that issue fast.
You're the Bob Ross of electronics repair. Fun to watch even if I don't know always how or why you do things. Instead of painting a pretty tree, you're shimming a pretty transistor.
Amazing Job done Mark ! I am watching your Work and it is so good to see the fun you have ! I love old stuff too and it is a pleasure to repair what is worth to be saved ! Rudi, from Germany...
Mark! Yes! I burned through the back catalog of videos, and have been impatiently waiting. So excited to see this post go up!
This guy is a god. All that complicated work..and then HE MADE THE KNOBS! Now how often have I thought, "I'll be done as soon as I MAKE some knobs"!
My favorite repairs are ones where someone else bodged it up. Yes, much more time is spent and probably no profit but its satisfying.
Mark, your repair was super-human...and THEN you fab'd up a pair of knobbers for it.
You're a *beast*
This is the best e-repairs channel on yootoob.
I have been an electronics technician since 1986 I have gone through the transition between black and white TV, digital TV, Bluetooth audio, wireless audio and so on. Many of my technician colleagues say this channel is the best repair channel in the WORLD. maybe my hope as your follower from Indonesia is. I hope you add Indonesian subtitles 🤗 and hopefully this channel will progress and continue to be there for us

43:43 Experienced turners will say that an emulsion (a 50/50 mixture of water and oil) provides a better cooling and lubrication effect than pure oil. This is why we see white liquid in production - the emulsion of water and oil will be white when the mixture is churned in the pump.
I was so impressed with your electronics skills. Then you got the lathe out, crikey, I think I'm in love!
Hi Mark. Thanks for the great video. I always love seeing you make things.
Just amazed you got that mess working so well! Excellent. 👍
WOW! what a mess you had to deal with ,and you have some beautiful test gear and brilliant job on the knobs, Thanks for the Video
Amazing! 99% of what you do goes over my head but it's enjoyable to watch someone who's on top of his game.
Pure Zen watching and listening to you Mark I love to watch you work.
These are the best repair videos on youtube. I remember lusting after Maplin's 1kW amplifier kit they sold in the 80's - all the boards and massive transformers and transistors made it look terrifying to build, I was just learning electronics then. And this is 5 x that power!
What a repair job! I don’t have much of a clue about the technicalities of the repairs you do but I still find your videos entertaining and a must watch. Thanks for taking the time to film and edit these videos.
Methodical and thorough, excellent to see all the steps! Thanks for sharing your repairs and awesome workshop.
I’m impressed, especially making your own knobs and they look really good probably better than the originals.
Fantastic repair by a very skilled technician!
So satisfying to see those waveforms come up and those custom made knobs. Beautiful work mister, you are a real craftsman! (added: don't you just LOVE tampered equipment).
I'm not even 5 minutes into this video and I'm so glad I found this channel.
Mark takes joy in his work
Excellent very entertaining repair job!
Very impressive repair Mark, I did not have much hope for that amplifier. Brilliant idea fabricating the knobs, I like those a lot. That amp was a total wreck, I probably would have put it in the “not worth repair” pile in my shop. You are always enjoyable watch repairing something. 👍🏻 Cheers from Chicago.
Awesome job Mark and very entertaining. 😃
Excellent repair Mark! A 5kW amp WHOA! 🤪👍
Your use of colloquial English makes your videos such a joy to view, the lovable West Midlands accent. Wonderful..
Looking forward to watching the bench PSU repair!! Good work on the amp repair though.
Well done, Sir. That was a proper job.
Super impressed at your attention to detail in the repair...and then you machined up some volume knobs, just excelled.
Amazing Repair !!! It's Mind Boggling the amount of Effort Involved to make this Amp. Work.
Pure genius ! this is what i call a quality repair job... the way you go the extra mile to make knobs is admirable ... your customers must be very very happy !
Madness crown rebadged a phonic amp, nice job as always mark
these always put me in a good mood
I watched two of your repair jobs. This Crown amp and the board. You sir deserve 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍's up. Well done, skills galore!
Superb work , Mark!
Great video again and wow I wasn't expecting you to go to the trouble of machining those knobs. Just goes to show what dedication you have in doing a good job.
Knowing Mark it wouldnt be a job finished without sorting some applicable knobs.
However he did make it hard for himself making those.
Nice to see someone doing repairs properly, attention to detail is fab !
Wow. I just found your channel and you took me back to my childhood - although my dad was never that brilliant a repairman. Well done!
Although I did imagine someone objecting to you painting the knobs outdoors and getting self-etching primer all over the flowers!
Asmr and successful repair puts my soul at peace!
Great video with a perfect outcome.
I hope your making a good recovery from your poorly back sir, take care & stay safe 👍🍀🇬🇧
Another wonderful work. You are an artist!
Killing it, yet again Mark! Love the repairs, keep them coming!
Always a pleasure to watch your videos, Mark. A true professional at work.
If only you lived near me! Love watching you wreak miracles on these broken treasures. In my case I admit to being electrically incompetent. I have a really sophisticated AM radio in my 1974 DS Citroen (you can have AM or AM) where the volume cuts in & out. I’m wanting to keep the radio - it’s true to the time of the car, but none of the audio shops hereabouts (Victoria, Australia) will even look at it… they are all in the ‘throw it away - we can sell you something much better.” Doubtless they would laugh at my stereo system Sonab speakers, Lenco turntable & B&O tuner/amplifier…
Mark, you should have a million subs. Great stuff here. I love this channel.
Great repair. Even I learned something !!! Beautiful job on making the knobs, true perfection. From 1 to 10, I rate you a 12 !!! Well done !!! 😀👍
That was insanity! Such excellent attention to detail and …motoring on as each problem presented itself, and, you resolved.
Loving your work and videos man!-)
Always exciting to see your repair videos
Brilliant work Mark. Service technicians like yourself are rare and hard to find these days. If i was closer to the UK, I would send heaps of work your way
I hope it wasn't anything serious about the power supply. Your work is admirable! Cheers from Argentina!
👍Love your work Mark!

Amazing job, the amount of dedication you've shown to get it fixed as well is great.
really great! since i joined i can't do without your videos anymore, i also learn the mechanics! for me the no.1.
What a brilliant job, Mark. Thanks for sharing.
Watching this in awe, you are so good at what you do - thank you for sharing!
