Just found Mark’s channel and I will be honest, as an electronic geek, I find every video so relaxing. I love someone who enjoys what they do. I’ve been lucky that I have enjoyed everything I have done but not the politics and management that I. Have had to deal with. This year, 2024 I want to retire and spend my retirement repairing things.. All the best
Is it because we are more discriminating and appreciate the honest technical abilities of Mark without drama, although an errant tie wrap initiated a fruity report .
Love your channel content. Was very surprised that you didn't replace the stylus, as a matter of routine servicing. A worn stylus could certainly explain the muffled sound. Great job.
Sadly, I'm not in the UK, but your videos help me to motivate myself and to understand better how the Wurlitzer 3000 of my grandpa used to work. I hope I'll finally make it run like when I was a child, he would be proud of me!
You must have some skills then. I know the simplicity of this kind of job is purely an illusion given by the vast experience of a seasoned professional
Nice to see old machines like this getting repaired and restored to working order. The designers of the jukebox did a nice job of making the system easy to work on.
Unlike most things yank made, wurlitzers were actually well made and designed to last. I cut my teeth on a 1947 bubble tube orginal that my old boss bought back in 80s. With no service doc i had to find my way around it ...but got there in the end. And quite enjoyed keeping the old beast going .
Great job Mark, that black oxide is sometime from H2S hydrogen sulphide, you get this from rotting bananas and other organic stuff, it is very destructive since it is such a good insulator. I had a switch room MCC at a paper mill that was badly ventilated and the busbars and motor contactors were black. The whole lot had to be disassembled and cleaned. Another issue can be when kit is exposed to near silicone polish that is bad news for relays as one BT telephone exchange found out.
Really late to this party, but adding a bit of context history on this beautiful jukebox: Wurlitzer's factory was in Buffalo, N.Y., near the city of Niagara Falls. With the sibilance I caught on final tests, it sounded like the stylus was knackered. Peeking in comments, I see you had wisely changed the cartridge, but I bet a new stylus would have made a world of overall difference. Still you made it sing wonderfully, cheers Mark!!!!
7:29 that is a really cool design! The way the plugs are neatly in a row, shielded and secured by a security plate is genius and a nice attention to detail. Peak mechanical design era.
OMG I basically grew up in the late 60’s and all of the 70’s best times of my life. I would love to have a room in my house with a jukebox like this and some old video games and other things. This is really nice to see someone to work on these things.
Brutal technology at its finest, that fascinated me even as a child, today I am 61 years old, and I am very happy that you showed this music box and its inner workings, thank you very much for that. I often ask myself what would be mechanically electrically possible if microcontrollers didn't exist. Today you have to be a programmer, back then you have to be a technician...
The electric hardtop on a 1950's Lincoln Continental ran electromechanically IIRC. It was pretty elaborate for the time and not un-prone to going out of alignment and jamming!
An awesome engineer indeed in the field of home audio, especially for those of us, audiophiles included who still use the equipments of the 70s,80s and 90s.These equipments were robust and designed to last with impeccable performance and with a great fan following.Iam 70 years old and still listen to my rack mounted system,I tell you they sound great.
Love the Channel Mark. A man of many skills. If I could please suggest you use a softer paper towel though. That green stuff goes through me. I don't know where you have found that.
Hello Mark, thanks so much for this fantastic video. It's a pure nostalgia overload. I remember popping some coins into one of these whilst on holiday when I was just 12 years old. Love and light to you from Paul in Bonnie Scotland 🏴. 🥰😇👍
that cable tie at the end made me chuckle, seeing only second video but already subscribed to see more. Look like easy job for you to fix that big machine. Never seen such beautiful jukebox, look cool.
It's incredible how these things worked as well as they did. Most were in pubs filled with cigarette smoke and drunks splashing beer around and bumping into it. All those mechanical parts and open contacts yet apart from some oxidation it's still as good as it was in it's prime.
I was thinking that too. I have worked on many old jukeboxes including early Wurlitzers that play 78 discs, and that grungy sound lacking in top end is usually due to a worn stylus. Edit - I just read further down that he discovered it had a bad cartridge. The rubber stylus mount had gone very hard. New cartridge fixed it.
Mark, you are awesome, amazing work as always, you make it look very easy! I bloody loved the FFS at the end and the F bomb when you lost the solder joint on the neutral 😂 I’m so childish.
All respect for You and people who engineering before , absolutely 😍 You are genius, I think only few people in the world can do a proper recovery restoration job for .., there's soul 👍
My goodness!?! My, how Wurlitzer built that massive cabinet! To me, it has an uncannily similar design to the likes of Willi Studer. Nice big huge hinged blocks with contacts sort of like backplanes. All really well thought out and thoroughly designed. There’s no such thing as overengineered unless your not an engineer.
I have watched a fair few of your videos and Mark l always thought you were a cool Calm chap very happy in your work but too hear you swear l was surprised 😯 l can’t blame you and I am not complaining but as always great attention to detail always good to watch you do your work 😊👍👏👏
Geeeez... As a young person: Whats a person gotta do to have the knowladge of someone like this? School? A EE PhD? Just do it? Have a good mentor? All that? I mean, I know loads of folks that have done this type of thing for years that dont have the wealth of knowlage of this guy. Whats the secret, Mark?
You don't learn repair in schools anymore. Register on a bunch of electronics forums, fix everything you can get your hands on, and find people who can assist you IRL with things you don't manage to finish yourself. Do learn theory as well! There are a lot of cargo culted 'repair' methods in the vintage world. Electronics theory can be learned in schools.
To think I used to put money in those to listen. My word. I had an old pair of Sennhiezer headphones. When the cable failed I had to get a new pair of Bluetooth headphones. It is amazing quality has risen so much in 20 years, or maybe I am 76 years old but goodness gracious these sound good.
Mark is right! Just a tiny spot of oil! Too much just attracts more dirt and causes more problems! I worked nearly 50 years on electronic and electro-mechanical machines! Oil getting onto contacts like circuits breakers ,relays ,switches only makes arcing worse and contacts burn out!
Mark, I sincerely appreciate that you are not a "nuke from orbit" guy when it comes to existing components. I have seen so many "repairs" done by "techs" who are, in reality, just "parts changers".
Mark you are SO good ---------- i really enjoy watching you at work ------------ headphones on --------------- and i can just relax ----------------- MARVELOUS
Great job. I’ve owned a 1987 Fuego which I thought was exactly the same inside but is a little different from yours. The carousel. Mine has only given trouble in the last few years on the end pick up. Thats the contacts at 12.36 they can only be accessed from the front. So difficult since they are at the back. Great informative video. 👍
With the next jukebox you may want to checkt the tonearm weight adjustment. Even if the stylus is fine it sounds like there's way too much pressure on the record.
Using the card/thick paper for cleaning has worked very well over and over even for magnetic heads, even video heads (as a LAST resort/if you know what you are doing). For the next level up I use a broken tooth pick (not for video heads). You can use the splintered end for minimally abrasive delicate cleaning.
Very very good job ! I live in France and I really regret not having such a talented specialist to repair my Niagara 2 Electronic! Anyway, congratulations on your videos.
Have you ever tried a regular red pencil eraser on dirty copper traces? I find it works most of the time for me, and it spares me from the terrible little fiberglass fragments; also leaves a smoother surface as it does not mar the copper at all
Blue Scotch brite by 3M for cleaning (fine) and Green for (heavy clean) Marvel Mystery Oil for light duty lube and freeing stuck screw and fasteners. Enjoy your channel, I too have had to make quite a few parts over the years (Copier and Printer Tech)
Hey! I met this guy in my Anger Management group years ago. Looks like that class is working for him better than me. THAT REALLY GETS MY GOAT! NOTHING WORKS FOR ME!!!
Nice job. Would suggest that the stripey green & yellow be left longer. Ideally, if the cable were pulled they’d loosen in line, then neutral, then cpc order
great Job mark! I felt ya `pain at the end !! I changed the master fader on a 20channel mixer last week for a mate. Fixed & Boxed up & all 150 knobs back on. Then I spotted 4 little screws left over after!! F.F:S . The National Battle Cry! I put them safely in a box with all the other STRAYS. Will reinstall them ( where i do not know) next time it needs fixing. Cheers from MADRID PS. do you recommend a stronger Solder iron for desoldering. I had a helluva job with my JBC 25w!
Hint: If you have resistors you suspect might be getting hot, it's worth putting a little glassfiber and silicone sock on them, especially on the older paper-based boards that don't tolerate heat as well as the newer glassfiber reinforced ones.
I see one cap in there that I might replace even if it tests good and that's the large-ish golden one. It's made by Frako and 70s through 90s Frako caps have a bit of a reputation, I've seen quite a few shorted ones. Many do still work but you never know for how long.
I have a 1967 Rockola. One of the last years that had an expose mechanism. The last bloke lol that had it converted to FreePlay and I convert it back to coins :-)
After cleaning all the spring loaded electrical contacts, why didn't you lube (Deoxit) them? Like 8:48, 11:57, 12:33 & 13:39 Also, it seems some bulbs are not lighting up (skips a few on the left side, and every other bulb on the right side). 29:16 Is that because the carousel not fully loaded with 45's?
great tips about esr meter and checking caps. i gotta service my 1982 sountracs mixer. was going to re-cap the whole thing. think i'll build as esr, learn to use it and save myself a bit of work. Also look into one of those caps discharge gizmos and a desolder gun..I liked and subbed a couple days ago. been binge watching ur vids Mark. love this channel. equal parts educational because you talk through the process and entertaining when you @#$% up..he is human after all :)
From what I've learned you need to be able to interpret the ESR readings though. Old ESR meters had a chart with acceptable ESR values for each capacitance and voltage rating. If I remember correctly the larger the cap and the higher its voltage rating the more ESR is acceptable.
Hello Mark. I just acquired a Niagara Jukebox and it also needs a new gas strut, but I am having trouble finding the correct one at a reasonable price. Any chance you could post a part number for your replacement strut, it would be helpful. Thanks for the video, it was very helpful in my first attempt at cleaning contacts.
Great videos. Just getting back into electronic repairs after a good few years away. What is the manufacturer of the soldering irons you are using they look nice. I need new kit as my old Weller station from the late 80s uses the old bits with the thermostat built in that are no longer available and my stocks are now depleted.
I like how Mark is permanently in happy mode.
Some people need drugs for that! 🤣

True. Let's thank us Tom Evans. 😂
@Mozart4000 It brought me here and I couldn't be happier.
Is it because we are more discriminating and appreciate the honest technical abilities of Mark without drama, although an errant tie wrap initiated a fruity report .

The confidence Mark has tearing this beast apart is truly amazing.
That cable tie comment at the end was incredible! Haha...that's the life of a repair tech! I've felt that pain a thousand times.
he should've filmed the whole disassembly again to get rid of that cable tie :)
29:05 started watching recently, and after quite a few videos, this is the first time I could really feel the frustration. A true man of patience!

The old Whirlitzer factory is now broken into a bunch of different shoppes and restaurants and stuff.
I see one cap in there that I might replace even if it tests good and that's the large-ish golden one. It's made by Frako and 70s through 90s Frako caps have a bit of a reputation, I've seen quite a few shorted ones. Many do still work but you never know for how long.
I do the same thing. Leave well enough alone on old capacitors. I only change them if a circuit is faulty.
Have to say I enjoyed that. 30:02 off to make a brew and see what other videos you have it’s 4am fek it
I wonder about mounting the 220 ohm resistor on the other side of the PCB, where there's better air circulation for better cooling?
I have a 1967 Rockola. One of the last years that had an expose mechanism. The last bloke lol that had it converted to FreePlay and I convert it back to coins :-)

Would you call that truly electronic? Looked a lot like snap and buzz technology. Loved his fastidious manner.
3 stars Jukebox service !
My recollections from the late 1970's early 80's is that the sound quality on these juke boxes were always muffled and poor quality. Great video!
Mend it Mark I watch your videos are so funny 🤣 to me I can’t keep watching your videos 12:06
I couldn't tell from UA-cam, but did the frequency response come back? It still sounded pretty muffled at the end.
