UPDATE: 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) The workshop is coming soon, but if you're reading this then you're in luck (or not)... And there's still time for you to sign up using the link below: www.menditmark.com/mend-mark-workshop The workshop dates are mentioned in the link above too.

Das ist großartig, Mark!

How on earth did you acquire such intricate knowledge of your subject Mark? You surley must have started when you were very young. With your enthusiasm for the work, you make it look so straightforward but to be able to identify faults amongst such a hornets nest of components is a truly gifted talent. Your videos are an absolute joy to watch.

The confidence of Mark is unbelievable, an example of an expert who smiles when something goes wrong.

Always a great night when Mark gets a new video out!

There's nothing like the glow of a magic eye. Brought back memories of when my late father used to repair these. Thanks Mark

And his Jap's eye as he waved it under your nose.

You made a fantastic job of that Mark, especially with the Bluetooth added to it.👏👏👏👍

I know nothing about electricity or electronics, but these videos are fascinating! Thank you Mark, always a pleasure!

i know quite a bit, but it facinatings me too 🙂

What an absolute gem to restore to beyond it's original capacity. Awesome work Mark

It’s a real joy to watch someone with such competence go about doing their work.

A lot of the German made radios had a lot of features like this in this era. They were made so well too. Lovely radios when you get them going. A lot of the paper caps and electrolytics in the filter will be needing replacing in these, but it is always good to see some proper trouble shooting done instead of just wholesale replacing the capacitors. A lot will be like this one and not operational due to the capacitors and sometimes resistors that drift in value. Those old paper capacitors go acidic inside and the paper breaks down,. They basically turn into resistors internally, which is why a lot of restoration channels will just replace all paper caps. The "Black Beauties" are also paper and foil inside. Guess it is hard when you are doing it for a customer to know how far to go as it takes time. The Ferrite rod in this likely originally had rubber mounts and plastic brackets that held the ferrite rod in place. Epoxy will stop it moving for a while. I usually put the bluetooth on the tape input on these when I do them. That way the bluetooth only works if tape input is selected. I designed my bluetooth module to run off the 6.3V AC heater line rather than adding an extra transformer :) There is usually plenty of power available and the bluetooth takes very little current.

If you ever need dual can caps, they still make them. I service tube amps and regularly order them. Usually from Hotrox or Watford valves. JJ, F&T and ARS are all decent and always available. Excellent video, as usual!

Mundorf make twin caps with a common ground pin too. Think it's the MLytic HV range.

Great to see another cheery journey through old tech with Mark. Great content - thank you!

As always, a pleasure to watch Mark. You really brighten up my day. They sure don't make them like they used to, in many ways it's so much easier today.

My late Father had 1 of these radios at our home in Essex...I think it was Bush but looks identical. I am in awe of your knowledge, skill and patience.

Mark has steady hands laying those micro parts in position. Amazing intelligence Thank you.

You cannot beat UK electronics engineering channels, so relaxing and informative. Big Thumbs Up.

In the mid-60s, my parents had exactly this Modell.Es was in our living room.I did an internship as a radio and television technician in 1976 and repaired the radio more often than it was defective. Greetings from Germany.Thank you great video

Mark makes working on electronics like tying shoes. He has such a positive demeanor when approaching a electronic problem. If only World Leaders be more like Mark 😊

Best electronics repair channel on yt by far. All the best Mark.

fantastico trabajo!!!! yo aprendi con valvulares en 1982 aqui en santiago del estero al norte de argentina a los 16 años. me trajiste hermosos recuerdos de esas epocas ... hoy ya etoy casi retirado del oficio a los 59 por la vista y la firmeza de las manos. pero el amor a la electronica no se va mas...me especialize en computacion a los 45 años y eso me permite prolongar el vicio que es la tecnologia electronica.celebro que todavia haya gente como vos que trabaje con cosas de epocas antiguas electronicas... saludos desde el norte de argentina mark de un colega que se niega a retirarse...

I remember as a teenager in the 1970s being given a Grundig reel to reel tape recorder . It was enormous and the most complex mechanical and electrical monster I'd ever seen ! It was built on a cast iron chassis , and all the piano key controls operated solenoids that in turn pushed and pulled all the various pinch wheels etc on the deck . It had a total of 8 valves ( tubes), and a huge finned selenium rectifier on the power supply unit. It was only mono , but the built in speaker was huge, and the microphone was a very heavy ribbon type. All it required was the heads and pinch wheel cleaning and it worked perfectly. The neighbour who gave it to me said it was from the very early 60s ,and cost the equivalent of around £ 200 when new ( bearing in mind this was 1971 and a new Ford Escort was about ? £750 at the time!

its unbelievable how the circuits were constructed without circuit boards it all hangs in the air .. brilliant repair!! nice work

Man, they don't make 'em like they used to... and good thing too. The transistor completely transformed electronic gadgets and made today's computers, internet etc, possible. Another great video. Excellent presentation and technical knowledge as usual. :) If I had that radio, I'd just have to try those speakers with a stereo amp and hear what they sounded like. Imagine stereo sound from that classic radio!

What a clever chap you are Mark. Even thought I don't understand electronics I still really enjoy your content. Brilliant!!!!!

And me. 99% of the time I have no idea what's going on, but that doesn't mean I don't find his repairs/restorations fascinating! Mark certainly knows his stuff.

I don't think I have ever witnessed a better electronics repair job ... Outstanding , Mark Cheers

Fantastic Mark one of the more challenging projects you have done and certainly one of the more interesting ones too. It amazes me just how knowledgeable you are nothing seems to upset you and you keep coming through with results. keep the jobs coming Mark you have a very loyal following we continue to need a "fix" from yourself. Take care.

Reminds of my childhood. The sound, the smell, the broadcasts. Great piece of history.

Amazing radio. I have the 1956 American version, different colors and the 4 smaller speakers are mounted on the side. Still all original, still gets played a few hours a week. 😊

Wonderful upload, thanks Mark. I really enjoy wizards like you bringing these old gems back to life.

Donnez-vous des cours? Je rêve d'avoir un si bon enseignant ici en France et avec toujours une si bonne humeur 🙏🥰🇫🇷

Questi sono i video che più mi fanno amare sempre e per sempre l'elettronica, ma questi video di restauro su valvolare sono eccezionali. Grande Mark 💪🏻💯👍🏻

31:58 Your initial repair brought Hall & Oates back together! Love your channel. Cheers from Canada!

Thanks for sharing your know how, and taking a 60+years radio and give it one more life of making music.. and demonstrating at the same time how precious thes old technologies were.. and they were within reach of the people who wanted to learn about them and repair them, right at the corner of the street, nearby. Now, try to open any recent Dac or Streamer and see if you can get it to work again.. my EAD Dac just died, and no one can repair it.. sigh. Thanks Mark! 👍

Great video! Those old radios sound wonderful! I have a Philco Transglobe that I enjoy listening while having my 5 o' clock tea!

Always find these videos soothing.. a professional doing a professional job with utmost pride in his work, and some bonus ASMR from the various screws and stuff being removed 🙃 Really high quality content.

"Thanks(for)giving" us another stellar peak into your brilliance in the workshop.

You really are an amazing technician. Love watching your videos.

Superbe video!!! I am an old man and I remember these. They were expensive and very good. Cheers from Patagonia. Argentina

Congratulations,friend Mark. I from Perú.I dont speak english. Y me gusta como abordas las reparaciones,con tu carisma y toda la instrumentación profesional. Dios te bendiga. God blessyou.

its all well over my head but I can see just how smart and talented Mark is at his trade, well done Sir and cheers from NZ

Mark you make it all look so easy. Great work once again.

I could go into deep sleep... every time i listen to Mark ... the broken electronics whisperer.

Stayed up till after 12 watching this. Lovely piece of kit. Well done on the fix Mark as always. Keep 'Em Coming.

That's what I like about old radios, you look inside at a wonderland - unlike the single chip and one or two surface mount components I have seen on modern things, they have no soul. Most enjoyable, thanks for sharing.

Absolutely love watching your videos Mark! Skillset is off the scale and also learned a few tips and tricks!

What a cracking piece of audio furniture! Nice video, Mark. 👏👏👏

Watched this with fascination, because although I'm not technically minded, the assurance displayed here made compulsive viewing. I do like restorations, and this one fitted the bill perfectly. Thank you Mark.

love watching you work, and i am surprised how accurate the VFO was with all those old caps

Mark, what can I say? What a fantastic vlog, full of so much content and skill. We'll done, I always look forward to seeing your work. Wish you could be more frequent with more posts 👍👏👏👏👏

Greetings from Wombourne, I enjoy your work and have watched many of your videos, always a pleasure. I,m glad none of the caps exploded when you juiced it up.

Wow! What a stress buster to watch Mark fix things up. Highly optimistic. Thank you so much. 🎉😊 Good luck and best wishes to you and yours.

My Mrs recognises the opening music when I start a video she always makes me go back to the start so she can see you get a shock 🤣 great work as always Mark, keep it up 👌🏻

Very cool... I grew up with one of these as my introduction to music, in my parents house...early 60's.. that magic eye always fascinated me when it was on... it was like something from outer space.. It also had a peculiar, (to me) smell... Sounded pretty good too from what I can remember... & it's probably the main reason I got into music & became a bass player. Great job Mark... I enjoyed every minute..

Great to see you back - really enjoy your content👍🏻👍🏻👍🏻👍🏻👍🏻

That took me back a few years. I used to sit with my Grandad in the early 70's and watch him "repair" old broken radios and anything else he could get his hands on, he never had the electronics you have, just screwdrivers, soldering iron and a hammer 😀. Brilliant stuff, liked and subscribed.

Mark, lovely old radio! I've collected vintage valve radios for 14 years, and what I've found is that initially when a radio is turned on after many years of slumber, it'll work okay for a while, but then the old capacitors will short or go open, sometimes explode after an hour or two's usage, so that's why it's advisable to replace as many caps as possible, even the low voltage ones!

You are so cheerful even when faced with a mess of failing capacitors.

Fantastic sound quality in these sets. I have an old 1957-58 Philips that needs attention when the time comes, (and courage) to put my fingers in it as i have next to zero experience in tube/valve stuff. Excellent video as always, i just love to watch your work!

Bravo you have given the magnificent old radio a second life.

I learn quite a bit watching these. Thanks!

Great Mark, i follow many restorer but you're my favourite. Thumbs up

Most satisfying. I love those sound from those old radios.

Omg I just found your videos , my late father use to repair TVs radios ,all those names and the components you mention brought back so many memories of when I use to watch him as a child ,im now 59, btw your knowledge is amazing how did such a young guy learn all about these old period sets , thanks great watching on a Sunday afternoon

Superb video Mark, enjoyed immensely

Dude, your work on the jam box 📻 was amazing. The fact that you customize pieces - so cool!

Well done Mark saving something ending up on scrap heap I am a bit like you I try to repair them if can to much ending up on the dump good video great repair

This was a great video. I love how you got this old beast to play smooth music.

Beautiful work, Mark!

Flipping awesome! Thank you! A lot of fun watching.

Nearly choked when you put the neutral on the fuse until I remembered our British plugs are fused. Very nice work.

Enjoyed every second of that. Thank-you Mark.

I’m fascinated by this, there used to be a fantastic wood cased radio where I served my apprenticeship it had a round front with big wooden louvres and a vertical tuner array along with the magic eye. I used to think about replacing the internals with some modern hardware and have a radio with what looked like a 1940’s American car grille.

your restoration makes me happy

This is so awesome had one of these as a kid they are built amazingly

Bloody brilliant Mark!, great job. What a skill set you have!

I've got a Grundig looks just like this with a runaway volume problem. Looks and sounded great until that happened. Surprising how good it sounded for its age. Shocked it still worked. Good to see someone so skilled keeping these going.

Beautiful radio. Nice work mate.

That's my Friday night viewing all taken care of. This is a nice long one, roll on Friday.

lovely sets, i had one and i wish i'd never sold it, great work as always

Throughly enjoyed that, so have now subscribed, thank you, takes me back it!

That was amazing!! Thanks for Sharing Mark...

28:42 I was surprised the coupling capacitor for the bass speakers wasn't a non-polarized type. All-in-all a fantastic rebuild. It seems when you fix something, *it's fixed!*

@peterlarkin762

You can use non polar caps for small and large signal coupling with no issues, as long as the offset voltage across it is a good bit lower than the cap's voltage rating. Polar coupling caps will introduce a tiny amount of distortion... In this old radio it wouldn't be measurable compared the amp and speaker distortions.

Wish I had the electrical skills of this guy very few people any where have this talent.

Brilliant. An old Opus repaired and upgraded with Bluetooth! ❤

Glad to see that you’re doing another video Marc this device looks like my father‘s Grundig blue spot radio that I still have too this day

Hi Mark, I'm using the VHM-314 MP3 BT stereo BT module - it's in BT5.0 version and doesn't bother with any messages, but your solution is perfect 👍 Nice day 🙂Tom

Nicely done with the radio.

Your knowledge, skill and cheery banter make you one of my favourite you tube channels! Thanks Mark!

Greetings from the distant land of the left coast of the colonies. You have an incredible knack for troubleshooting followed by the ability to rectify those problems! That’s not even discussing your excellent video and sound quality of the videos.

Great job Mark. I restored an old Selmer amplifier recently and Watford valves had quite a few dual can electrolytics in their stocks.

My German friends sent me one bluetooth device that connects thru the bird’s eye and the plugs in back for the speakers. Genius! Works well. Have a hum on radio but i think some ground issue. Telefunken opus

I have one at home right now, better shape than the one of the video because it works when i turn it on but i'm going to give it a little clean up maybe change a tube or two and try to set up a bluetooth mod with this video as a guide :)

Brilliant work matey! Andrew Collins Melbourne Victoria Australia.

first class work Mark,well done..and a really nice piece of vintage radio..great video.

Amazing!!!! You almost did that radio again to bring it back to life!!! Now it is a Markefunken!!!

Absolutely wonderful and the icing on the cake was listening to Andrea at the end of the video.

Thanks for another great video Mark 😊

Top notch as always Mark

bonjour de la France mark ,je connaît strictement rien en électronique , quel patience ,et quel savoir faire ! vos vidéos sont excellente et passionnante a regarder ! tu a gagné un abonné.

Mark,you are simply the best.pleasure to observe

Cool old radio given another 66+ years of life and Bluetooth! Imagine what the Germans who build this would say about the BT tech. Nice work Mark!
