Some people need drugs for that! 🤣 (Due to an infestation of humourless hate-filled trolls, and the general toxicity of social media, I no longer monitor or otherwise revisit any comments I may make!)
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
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.
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...
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.
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 🏴. 🥰😇👍
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.
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 could also use a graphite light lithium combination lubrication for those groups of many contacts. This will not only stop the noise, also, this ensures good conductivity for a long time to come.
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 👍
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 .
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.
Mark you are SO good ---------- i really enjoy watching you at work ------------ headphones on --------------- and i can just relax ----------------- MARVELOUS
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.
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.
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.
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!
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.
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. 👍
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.
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.
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 :-)
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.
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".
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
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.
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.
Hi Mark, I have this same jukebox. It will work other than the arm won't grab the record from the carousel and place it on the player. Any idea what would keep the arm from working?
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 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!
Hi Mark great video,, I have a niagra 2 the gas strut was taken off and not sure what length strut I'm looking for can you help please Dave ..thank you ..
Hi Dave, it’s 500mm (extended length) with 8mm eyelet fixings. 300N force. Just look for Universal Gas Struts on eBay or similar- they’re not expensive.
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?
Hi Mark, amazing video. I have the same jukebox with similar issues so will set about it at somepoint. Just wondering if you can advise what size barrel lock is needed for replacement as mine has been drilled out in the past. Many Thanks
I just dug my notes out... The main body is 16mm diameter, with a 19mm bezel. The body length needs to be 25mm long so that the catch lines up with the slot in the lid. I did have to open the hole up a bit to make it fit, and I had to adjust the latch (arm?) length. Be prepared to fettle!
I've worked on many jukeboxes over the years and always been disturbed to find that people have butchered the key locks by drilling them out. It's completely unnecessary, even if a key has been broken off in the lock (there are ways to extract broken keys). Replacement keys and locks are readily available for almost every brand and they are common to every machine so there's no need to drill locks or replace them.
I have watched plenty of your videos, I have seen you using some foam cleaner. I was wondering what type you use, specially for electronic parts and boards?
I like how Mark is permanently in happy mode.
Some people need drugs for that! 🤣

Thank you for the information. When we were childrens we were listening to this machine, but we don't know how it was working. Thank you.

Good job. I was thinking it may need a new stylus/needle. A friend of mine used to check them with a microscope.

7 plays for 50p! You could have had close to 10 minutes of Television's Marquee Moon for just 7p! 🤣
Fantastic work as always Mark.
Mark....You are simply GENIUS!
What a pleasant personality . Everything explained with a smile
What a beautiful piece of kit brought back to life and restored to it's former glory. Well done!
Beautiful machine especially with all the lights working for the night ❤️
Very nice fix! I like your videos!
Love the sound when you were testing the speakers. Very 50s sci-fi movie.
Watching these videos is so calming... it's almost like meditation...

You make everything look easy

Brilliant as always!
what a beautiful machine
Wow Mark nice to see a properly made Jukebox not like the rubbish cd player type, lovely sound I bet as well thanks nice repair techniques too thanks
Great old machine :-)
Made to be serviced and repaired and built to last forever it seems 😮
Fantastic work Mark!
Loved this one!

It's great watching you trouble shooting. I'm surprised that you didn't change the stylus, since the amp. was in good working order.

Mend it Mark I watch your videos are so funny 🤣 to me I can’t keep watching your videos 12:06
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!
Mamma mia che bellissimo quanto mi piacerebbe averne uno in casa mia, 💯💯👍🏻👍🏻👍🏻
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!
I couldn't tell from RUclips, but did the frequency response come back? It still sounded pretty muffled at the end.
I'd usually use a dielectric grease on the wiper contacts. I know the oil works, but the grease tends to stay araound a bit longer :).
Great jobs Mark. When can I bring my jukebox Round to you I broke it lol But I’m sue you can Fix it
