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?

I want to try something new. Something more live.
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)
From the 1950s all the way to 2020s.
It's still just an idea. The dates and times are to be confirmed.
But if you're reading this, then the workshop hasn't yet taken place.

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.
Mark - you are my hero in this age of throw away out of date technology.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!
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
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
I want to see the bench power supply repair now 😅
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?
I like that every stage of the repair comes with a little chortle!
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.
The amount of care taken in fixing someone else's mess...
Is remarkable and commendable.
Thanks for a great video 👍
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 😂
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?
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!
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.
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.
Already looking forward to a power supply fix video! :)
You are such a cool person with a wealth ok knowledge that most people don't have these days and great sense of humor
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 like how you just giggle at the different kinds of fasteners, instead of getting frustrated that someone put a bunch of random screws in
Really impressive work! And the surprise fabrication at the end was such a cool bonus. Bravo.
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

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. 🙂
Amazing Repair !!! It's Mind Boggling the amount of Effort Involved to make this Amp. Work.
Great job very professional and time consuming locating the parts, l bet your customer was over the moon with that quality repair.
Insane repair, your skills are amazing.
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.
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
Perfect amplifier for a small flat.
Brave lad our Young Mark! Especially when someone has been in there before and bodged and given up!! Good man!
ONCE AGAIN MARK YOU HAVE NAILED IT ........YOUR AN ABSOLUTE ELECTRONICS GENIUS WELL DONE TO YOU SIR
Madness crown rebadged a phonic amp, nice job as always mark
Mark, the happiest repairman in the web! 😄
Amazing what you do. Attention to detail that is Mend it Mark. Enjoy watching your work. 👍💪💪🇩🇰
Mark! Yes! I burned through the back catalog of videos, and have been impatiently waiting. So excited to see this post go up!
My favorite repairs are ones where someone else bodged it up. Yes, much more time is spent and probably no profit but its satisfying.
Again, a LOT of fun ! Merci !
Spectacular work..
Boy, that one had seen some better days, rode hard and sent home limping.
Excellent work mate.
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 😊 👍
Excellent repair Mark! A 5kW amp WHOA! 🤪👍
This gentleman is so very thorough
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"!
Excellent very entertaining repair job!
I just discovered your Cannel. I feel very good when i see you smile. Greetings from Germany
Once again easy to understand. and easy on the eye. Brilliant just want more please?
The rivets on the pots is a great idea 😎 Certainly one to file away in my brain somewhere.
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…
How can a person be so positive all the time. I guess he leaves all the cursing to me when I make mistakes. Now I understand.
With all the repair channels on TH-cam 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 🤣
For some reason I enjoy watching these videos.
Me too. It's like Dr Pimple Popper for polite people
Well done, Sir. That was a proper job.
Methodical and thorough, excellent to see all the steps! Thanks for sharing your repairs and awesome workshop.

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!
Brave. Masterful. Exemplary. 👏
Superb work , Mark!
Your use of colloquial English makes your videos such a joy to view, the lovable West Midlands accent. Wonderful..
I hope it wasn't anything serious about the power supply. Your work is admirable! Cheers from Argentina!
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 love watching people who know their stuff. Subscribed 👏🏻👌🏻
Awesome job Mark and very entertaining. 😃
I watched two of your repair jobs. This Crown amp and the board. You sir deserve 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍's up. Well done, skills galore!
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. 😊
Cracking job Marc outstanding work.
I was so impressed with your electronics skills. Then you got the lathe out, crikey, I think I'm in love!
I’m impressed, especially making your own knobs and they look really good probably better than the originals.
👍Love your work Mark!
Mark takes joy in his work
The most wonderfully cheerful technician on the Tubes :)
well done for taking this on...lives to shout another day.
really great! since i joined i can't do without your videos anymore, i also learn the mechanics! for me the no.1.
Nice to see someone doing repairs properly, attention to detail is fab !
Wow, great video, and happy chappy. I once had a Peavey CS1000 posted to me in a flimsy cardboard box. No packing material or effort made to ensure it arrived safely. It was completely smashed up, and it took 6 months to get a refund. Those machined aluminium knobs look incredible. You're definitely ahead of the rest
I just love a challenge! Mark must have come out of the same mold!
I'm not even 5 minutes into this video and I'm so glad I found this channel.
If I had someone like you closer to me, I would love to learn… Amazing work
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😊
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
You truly are a knob expert ...in the nicest possible way.
This is the best electronics channel on TH-cam!
Although intuitively the right thing to do, I`d advise againt actually mirror polishing surfaces for heat transfer where there is paste being used (other than making sure they`re flat), because a rougher "satin" type finish actually has a higher heat transfer area as microscopically its like a little mountain range. I`m sure that will make no difference at all here, but in principle, its better.
The Dr Hibbert of Audio Equipment Repair. God I love this channel.
Outstanding various skills .
Editing must have taken ages.
Great content,and glad there are still very clever English men around .
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 a courageous soul, trying to fix where others have already made the fault worse. There be dragons!
I reckon you were very lucky those big toroids were OK. Had there been a problem with those, things would have got very expensive very quickly.... assuming you could get anything similar, which is not a given in these cases....
I reckon most people opening that up would see the rat’s nest and just put the lid straight back on again. But not our Mark! It doesn’t matter what your field of expertise - if you leave the world in a better state than you found it, good on you 😎😎
Leaving the world in a better state than you found it...... is that like being born in South Dakota and Dying in Texas? im kidding lol
Pure Zen watching and listening to you Mark I love to watch you work.
Asmr and successful repair puts my soul at peace!
Crown amps are only good for a few things: Blowing up speakers, Setting speakers on fire, oscillating and blowing tweeters, unstable operation, and they make great boat anchors.
I used to service many amplifiers for cinemas and live sound. Crowns were on my bench at a ratio of seven to one compared to ALL other brands combined. And despite the hype, they do NOT sound "cleaner" or "better" than most other brands. And to top it off, they are one of the most expensive amps made.
The most reliable brand out there now? QSC, hands down. The ONLY repairs I have had to do to QSC were minor. Dirty gain controls, worn out cooling fans, and the very rare output stage failure.
Probably any "normal" citizen could not aprecciate this job like me as an engineer I must say this job is beautiful . saludos
Just amazed you got that mess working so well! Excellent. 👍
Nice. Love the way you mostly end up doing metalwork in these videos.
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!
That was amazing!! Junk to treasure...
these always put me in a good mood
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.
You started showing up on my feeds a couple of days ago. I've got to say.. wow! You'll often find people can be one trick ponies. One skill in life. When you realised you didn't have the correct knob for the resistors .. switches on a lathe.. I was all.. right, hold on man. This boys got it all. Then you stood in the garden spraying the knobs. Grass is like my pool table. Perfectly flat lol I bet in your cupboards the tins all face forward, towels in kitchen are always balanced? .. you're a good guy, even the chuckle at the exit of every sentence makes me chuckle. Keep it up buddy! I've seen others on here. Really good stuff too but your detail, explanation and understanding is brilliant. My prised Sony amp has a fault, once turned on it's fine for 1 to 5 or more seconds. Sends a horrible buzz through the speakers and fails. Needed turned off/on originally but has given up now. I think it's going to be something very similar - this video + another channels video both point to the black X3 pin parts. Oddly too, my Sony amp, if it's volume 0 or volume 100 (example) .. the horrible buzz/electrical sound is loud. I remember when it was working but giving up it used to click. Like a click clock sound.
Great video as always. Greetings to the magpie at 4:32
Would gladly buy refurbished gear from this guy ... Those old Crowns is top notch quality. Not even compareable to todays Class D crap. Only downside is the weight. You need 2 bodybuilders to handle a rack of 4 of these 😵💫 Great job on restoring it.👍
Stumbled on to this channel....Excellent.
Very professional work👍👍
Hi Mark. Thanks for the great video. I always love seeing you make things.
