1982 Boom Box Repair (Telefunken CR100)
Mark repairs a Telefunken CR100 Ghetto Blaster, which has blown a fuse. The underlying cause requires some digging, and missing parts get re-manufactured on this 1980's classic.

Great repair, but the crafting of the new knob was totally unexpected and brilliant.

Mark, you make some of the best tech repair videos on KZread. I know it takes time to make these as you use superb camera angles, great audio, perfect lighting and above all, friendly attitude. A pleasure to watch and learn from you mate, keep it up! Regards from another Mark here in Australia 🦘🦘

yea, I'm trying to self-learn electronics repair while I've been waiting to go back home to Donbas for almost a year and this chan is great, only' just foind it, Ben Heck, way too full of himelf and kinda arrogant, and poor old techmoan, he doesn't know what he's doing as he admits in his videos. Mend it Mark is kinda in between them, just right!

@@irongron Keep up learning, that's a good thing! I Did it the same way... Reading, reading, reading... Learning, trying... Failing, learning... It took me a long time but now, I'm able to repair and even design electronic circuits. Let's pray the war will end soon.
I really enjoyed the last part, making the switch cover replacement. Was so satisfying to see the boom box get this final touch.
I am in awe over the power you yield over electronics
It's a pleasure to see a good mechanic put things right. Made me into a fan, keep em coming.
Your enthusiasm for fixing a classic old boombox is brilliant. Well done great to watch
I catch my zen when when watching vintage audio repair videos. Glad youtube recommended me this channel, lotta more calm hours ahead!
You went above and beyond what I expected - I would of given up at the fuse! Making another lever switch that fitted perfectly was nothing short of genius. Hats off to you.
Very Nice..i always get sentimental if seeing the Telefunken logo. My Grandfather worked there as a chemical laboratory assistent back in the days. I still have some Telefunken tubes in my VOX AC 120 Guitar Amp from the early 70s. 😁👍
Your enthusiasm and chuckling here and there, cleverly merged with detailed instructions made this repair job a pleasure to watch. Thanks so much.
so satisfying when all knobs are complete
It's all reassembled, but 8 minutes to go. What went wrong? I ask myself. Then the suggestion to make a new switch cover. That was a mymechanic moment of the day. In that channel, he often has the text, "I make a new one". Love it.
The switch replacement I wasn't expecting and it made me go WOW - well done Mark! Greetings from Glasgow (and the Highlands). Love your enthusiasm!
Mark you are a true artisan and an exception to the "jack of all trades" rule.
A Lemon Cake, a mug of sweet Coffee, and fixing a Boombox from back In the day. What more could you ask for on a Rainy Thursday Afternoon. Keep 'Em Coming Mark.
Good job again Mark! The trouble you take to mend a humble radio/taperecorder. .. Just amazing...
Brilliant.. the making of the switch cover was a stroke of genius.. bravo.. bravo..
I am always stunned by your knowledge and dexterity!! It is always such a pleasure watching your work!
I like how older electronics were built with serviceability in mind. Back then the culture of consumerism didn't kick in yet and people were still used to repairing their devices rather than throwing them away and buying new ones. Awesome piece you got there!

So relaxing to watch
Awesome work :) Hope this dude gains a very high sub count :) The work he does is consistently brilliant... Ive just started electronics repairs as a hobby, and learning as i go. Wish my knowledge and skills get as good as this dude, in the future :)
Mark, you are just simply incredible, you make replacement transformer ( for the monitor repair ) and now you even make the replacement switch !. Other engineers if they encounter such similar broken parts, they would have simply just gave up with the excuse - no more spare parts !. But you are different, you just fix everything and restore them. Just love watching your videos and a subscription for you.

Don't blame other engineers, please. It's a matter of tools availability in a workshop, not an attitude. I'd rather call Mark kind of artist in his craft
And he has a fully equipped metal workshop as well! Whoa.. You sir, have just risen to the top of the ranks of awesome people! :-)
Mark, I just want to say that I've discovered your channel a few months ago and I'm amazed with your repair videos as well your good mood all the time!! Thank you so much!! My grand father had the chance to get one of these bomboxes directly in Germany during the 80's, but the brand is 'Sound 4010'. It's basically the same but with some minor differences in the faceplate as well radio dial. Belt kit replacement and a nice clean, with also a Bluetooth small module, and it's back to life! It sounds amazing!
Been watching your videos for about 3 days now. I am a amateur electronics hobbyist. That being said one of my reference monitors started to flake out on me. I pulled a "Mark" and ripped it all apart and noticed some solder joints, and I freshen them up, cleaned the connectors and then tested for a while. And wow. it was fixed. You're an inspiration, its amazing the level of detail, troubleshooting, and creativity you show in your repairs you share with us. Thank you.
Busting out the lathe to make tgat knob was next level, totally unexpected. This has quickly become one of my favourite channels
Brilliant work, the new switch cover is just a perfect finishing touch.
Nice job on the replacement knob cover. You are a talented craftsman! Man, I wish I have that ghetto blaster back in the '80's...
what a pleasure it would be to go over and learn a few things from a neighbor like this.
Mark you know what you do is actually good for the environment because it means that this electronic equipment doesn't go into landfill it's actually a good thing that you do and it saves the environment I really like watching you repair this more people should get this done and more people should learn it you're very talented
I had opened a lot of tv's, radios and other things in my younger days, and I always tried to find the thread in the plastic where the screws were. On a few occasions when a repaired item came back from factory, they did not do that, they made a new thread in the plastic, causing it to become brittle and would give away, breaking the screw from the plastic. This method I tried to bring to my apprentices over the years of network- and system administrator. Sometimes it is hard to see that not every repair guy or girl keeps track of threads for screws. Hope you do!
Damn...the repair was above and beyond....and THEN you fab a lever cover. Fantastic!
great repair Mark, you are amazing. very skilled across many disciplines. Thanks for the videos, entertaining and informative.
This is a very talented man. Found the channel recently and love it.
Good job Mark ! Best regards from Indonesia..
On 1990s I often repaired radio cassette tape like that, you make me remember back to those good times.
Wow, Mark, I mean just wow. Excellent work.

Keep up the good 👍 work please 🥺🥺!!!!
very impressed by the alu button cloning !
love that you machined a brand new knob
Oh my god, wireless worker, you actually started a lathe. That's really fun!
I had two CR 100’s many years ago. Completely different beasts to this one. They were made by Marconi, and were 100khz - 30mhz communication receivers. That was the start of my amateur radio / ham radio hobby. How things have changed. Thoroughly enjoy your videos Mark, long May they continue.👍
I admire both your knowledge and skill to fix these things. As a child, I was great at taking radios apart... it was the putting them back together again I never got the hang of. I also learned after a while that my capacity with a soldering iron was nil; I would solder all over the room, but none on the actual connection! While I wish I could do what you do, I can still watch and appreciate your efforts to bring electronics back to life.
Mark, You are a man after my own heart. I do repaire on music equipment and always do a little bt extra to make sure i an satisfied. I love you channel and approach to diagnosis. you have taught me a lot. Keep up the good work!
Boy! What dedication and passion to his profession. Amazing indeed. Thanks for the inspiration. 🎉
Pure genius. Making a complicated job look so easy . Your attention to detail is amazing.
Awesome job Mark. Great bit of fault finding and the switch cover you made really set it off well. Lovely boombox. They don’t make them like that anymore. Cheers Graham
I liked the tinnitus test tape you popped in before the Hole. I'll be hearing that one in my head for a bit. Real catchy!
I wondered would he yeah course he would, waited till the end and I was not disappointed. Great stuff as usual learnt something.
Wow, genius, and that knob turned a repair into a complete perfect job, must have been super satisfying and the owner was sure to be overwhelmed.
The button cap was amazing pal 👌🏻
Watch ya all the time Mark - in my book, you're always amazing, this boom box project is no exception - even the knob! - fantastic - love the vast variety of skills you possess and bring to these rejuvenations. Thanks for giving us the perfect "bird's eye view" throughout all of these interesting journeys you bring us on.
I like the way you do your video's! And your always happy and smiling! Nice work on the knobs replacement! The radios were the best thing in the eighties!
Fascinating, particularly the new switch cover. All the best Mark!
I had similar Boom Box, "Sanyo" from 1982. - Our Mark is The best Meister - ever !! :)
Only just found this channel, your like me in doing electronics repairs. Most channels I do like on here but this one I do. Your a nice person and not a big head, I done electronics for 35 years and I find on your way in this subject you meet big head or people who don’t know what they are talking about, has it been the same for you? Anyway nice to find a channel with someone being nice and helpful to the viewers. Nice one mark.
I knew you were an electronics genius. When I saw your machining skills I was not too shocked. Masterful crafting.
From electronic to metal working in one video. Very impressive indeed.
You're a machinist too! Wow! Amazing
Excellent work as always. Just a couple of points from my own point of view...I try to avoid cutting the print track to isolate chip pins. I always suck all the solder from the pin and its pad and then manipulate the pin to centralise it in its hole with forceps and/or a very small jewellers screwdriver so that it's not in electrical contact with the surrounding copper pad. I then solder a small wire to the actual pin and another to the nearest convenient solder pad to make a test connection. This saves marking/damaging the original print track and necessitating bridging repairs later. Regarding solder bridging on cut/broken print track, I tend to solder a a fine bus bar wire link across broken print track for mechanical strength - it's the way I was taught back in my C&G college course days. The fault clearing after removing and replacing the transistor is a strange one, as I couldn't spot any solder bridging as such, so it's just remotely possible that the transistor had a junction fault that was cleared when it was heated and manipulated when removed. I had a similar fault a few years ago with one of those back to back 3 legged varactor diodes in the FM tuner section of an old JVC boom box, where manipulating it cured the fault and it carried on working for years afterwards. Keep up the great work and excellently filmed and produced videos - you're one of the best!
Just found this channel, That's a superb repair, that looked like a good quality stereo, the way it came apart, with each section able to be unplugged fairly easily. Unlike many of today's un-repairable items which are glued or clipped together! The cherry on the cake just has to be the manufacturing of the replacement switch cover, great bit of engineering!
A classic German boombox (Telefunken) from the 80's in perfect condition, the function switch is identical to the original, perfect ! 😉
What a flex. Watching in awe, an electronics repair guru. Guru then busts out a milling machine and lathe.
Hi Mark I have been watching your channel for quite some time now. I must say when I saw this one it took me back a few years as I had that same radio. Thanks Mark and keep up the great videos. Kev
Laser print a plastic knob? No way. This is how it's done💪
I binge watched your channel for four hours yesterday! It takes a brave man to open up a boom box that's for sure. I wish I still had my Sharp GF9191 Seriously impressed that you made a new knob on the lathe, very cool indeed.

Awesome, I had a Panasonic somewhat like that many many years ago, brings back memories
Simply impressive.
Superb work mark and even better you made that missing cap that really finished it off .
fabricating a new knob is the cherry on the cake, magic

Ah, the good old TBA810. They were a popular audio output IC in a number of colour TV sets that were made here in NZ back in the 80s. I remember replacing more than a few in the early part of that decade.

Brother, you have veeeery thick nerves doing all that tedious job - I admire you! Very good job, thank you for sharing it with us. Keep up the good repairs my friend...
that era was when radios were made with good quality parts and good plastics
You've got quite the tools in your workshop. Well done.
