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

I really enjoyed the last part, making the switch cover replacement. Was so satisfying to see the boom box get this final touch.

Mark, you make some of the best tech repair videos on KZfaq. 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 🦘🦘

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

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!

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.

Fabricating that new knob was brilliant! You, sir, are a steely-eyed missile man. 😊

Your enthusiasm and chuckling here and there, cleverly merged with detailed instructions made this repair job a pleasure to watch. Thanks so much.

I am in awe over the power you yield over electronics

Good job again Mark! The trouble you take to mend a humble radio/taperecorder. .. Just amazing...

I am always stunned by your knowledge and dexterity!! It is always such a pleasure watching your work!

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. 😁👍

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.

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 satisfying when all knobs are complete

Mark you are a true artisan and an exception to the "jack of all trades" rule.

Brilliant.. the making of the switch cover was a stroke of genius.. bravo.. bravo..

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.

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.

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! :-)

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 :)

Hearing Jupiter by Gustav Holst did my heart good, my absolute favorite classical piece. Awesome job getting that cool old tech going again!

Brilliant work, the new switch cover is just a perfect finishing touch.

Pure genius. Making a complicated job look so easy . Your attention to detail is amazing.

Huh! There is a real 2-way speaker in in. That´s impressive! Great video, thank you for your good work! 👍

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!

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.

Busting out the lathe to make tgat knob was next level, totally unexpected. This has quickly become one of my favourite channels

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 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!

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

Boy! What dedication and passion to his profession. Amazing indeed. Thanks for the inspiration. 🎉

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.

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.

I knew you were an electronics genius. When I saw your machining skills I was not too shocked. Masterful crafting.

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.👍

love that you machined a brand new knob

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.

Fascinating, particularly the new switch cover. All the best Mark!

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!

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!

Damn...the repair was above and beyond....and THEN you fab a lever cover. Fantastic!

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

great repair Mark, you are amazing. very skilled across many disciplines. Thanks for the videos, entertaining and informative.

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!

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!

Nice fix and a special treat at the end with the switch cover. Enjoyed watching 👍🏻

Your level of craftsmanship level just went up to 11 with that one. I'm a new subscriber and will continue to be so after this restoration!

I love the way you bring these good old machines back to life, excellent video!

Superb work mark and even better you made that missing cap that really finished it off .

Brilliant troubleshooting and fabrication to boot! Your body of knowledge is truly impressive.

Wow, Mark, I mean just wow. Excellent work.

The button cap was amazing pal 👌🏻

Oh my god, wireless worker, you actually started a lathe. That's really fun!

So relaxing to watch

Glad ppl. are repairing boomboxes and vintage stereos. In 1979, I had the top of the line Sanyo M9994 boombox and Corte like $270. US and loved that thing. I just saw one listed on eBay for &3,000. and suppose to be one of the top 10 classic boomboxes it was on the cover of Malcolm Mclaren’s Buffalo Girl’s album from the 80’s. Also I used to plug in a turntable and sounded like a full stereo bc it had a built in phono input and pre amp. Anyway, most boomboxes need new belts being sold and you can still get them cheap bc not many know how to change the belts.

On 1990s I often repaired radio cassette tape like that, you make me remember back to those good times.

Wow..the video is great. At the end when Mark jokes with us about the knob, then like it's no trouble at all begins to fabricate one 🤯. Just amazing..a pleasure to watch, Marks' a true professional and nice with it. Best wishes everyone 😊

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!

From electronic to metal working in one video. Very impressive indeed.

Hi Mark, Nice to see another video, were always craving more, always enjoy watching your repairs and great personality, keep up the good work

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

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.

Mark. Really enjoying your repairs with tips included. I was in this business for many years but retired now. In my 70s now but still fondly remember out on the road in a company minivan then a mk1 Ford escort wow. Any way carry on the good work. Cheers.

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...

Fantastic, love that you made the knob by hand, great work.

Nice one, Mark! Excellent repair as always - and that new switch sleeve was awesome, matey! Paul

Another great repair, Mark. 👋

You are from another planet My brain exploded when you started creating the knob. Amazing! Congras!

Wish you put up more videos mark. Great videos all the way through. I’ve watched all of your videos now so having to wait for the next one 😮

You've got quite the tools in your workshop. Well done.

Very well done, I'm so astonished of the fact you did a marvelous job, plus made another knob for the Radio Cassette, your definitely a genius, keep up the sustainability. 🙏💯😅

That’s an A class repair as ever Mark 👍🏻

This is a very talented man. Found the channel recently and love it.

Just found your channel. Love your smile when taken something apart. Keep up the work and try not to get sparked to much...

What a flex. Watching in awe, an electronics repair guru. Guru then busts out a milling machine and lathe.

A classic German boombox (Telefunken) from the 80's in perfect condition, the function switch is identical to the original, perfect ! 😉

nice repair and a good piece of fabrication at the end early 80's always popular with me mate well done

Excellent work, it shows that you are an artist and a very high-level technician. Congratulations. Greetings from Chile.

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.

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.

Another good repair, good work there Mark.

I wondered would he yeah course he would, waited till the end and I was not disappointed. Great stuff as usual learnt something.

Simply impressive.

You're a machinist too! Wow! Amazing

Jeez, Mark! Always going the extra mile. Love it 😎🤘

Ah the icing on the cake at the end 👏👏 Looks just like a Toshiba I had for many years, hammered it & ran into the ground, wish I still had it now.

I really like your videos. I would love to see more of tape recorders, VCR's, TV's.

So awesome mark ❤️❤️❤️❤️❤️❤️ blew me away with that switch cover at the end.

great video - I hope you will make many more of them. love 80' Electronic.

I enjoy your British voice. The constant "Ah", and "Eh-heh"s are priceless!

Hi there Mark i had this exact boombox when i bought it the right hand chip was faulty, i recapped it and replaced the right hand chip along with servicing the tape deck, this was working perfectly for over a year then i sold it on.

just found your channel, super impressed with your workshop

Not only good with electronics, but just as good with milling and lathing. Real champ!

Hi Mark, it’s week end and it’s time to bing watch your videos back to back, by the way the knob was just brilliant. As usual workmanship at it’s best. So excited to watch video on SONY Zilbap

Jeffin awesome Mark!!! I was so glued to this my beer got warm! :D Outstanding with the machined part to end too!

Really good job, 👍 nice to watch and nice outcome Sir 👍 👌
