Manuel, I've said it before but I'll say it again: Thank you for showing us what is possible. We can fabricate parts and accessories for this restorative work. Bring it on!
I like the idea of a separate blue tooth module. Great idea solve all interference and heat issues as well as preserving the authenticity of the radio. Excellent.
If changing the functionality of a connector i try and change the number of pins or use a different locating index if there is one. With din sockets changing the pin count is quite easy. Just a thought and a great project
I looked into that. I tried to leave the “mono” pins the same and used the record out pin as the supply. Hopefully that reduces the risk of any damage to connected equipment.
I agree with @TheEmbeddedHobbyist - I think it would be safer to fit a 7 pin DIN socket (and matching plug) and use the extra pins for your 6.3V supply and ground. A 5 pin standard plug would fit for anyone who wanted to use it for its original purpose and with no risk to their equipment.
Great video of a great restoration! Very cute little radio, Braun deserves props for making this tube set so small. The bluetooth solution also makes sense here.
Hi Manuel, nice job! Just in case you’re not familiar with it, you can use spot putty to finish the filling and smoothing of those small imperfections. You might also see it called glazing putty. It goes on like body filler but sands like primer. It’s effectively a thick primer putty.
Great job on the back cover (and everything else).Those LASER cutters really are good if you spend the time adjusting them initially. Likewise with surface mount soldering, it gets easier if you invest the time. But then it depends what you want to prioritize your time on.
It looks fantastic. The dark gray is really nice with the off-white. It would look great in my kitchen, are you sure you want it 😉Only kidding, nice job, best wishes to you.
In the classroom where I work we have a Glowforge Laser engraver ! I have a Philco flying wedge that is missing it's back that I plan to make a new one .
Nice work!! Those are great little radios!! I was thinking you were going to make your BT module to hang from the slot at the top of the back, with two nubs that sit into the holes on the back making it attached, but still modular. Very nice though. 🙂👍🏻
Excellent restoration, as usual! While I admire your resistance to making visible modifications, I must admit that I probably would have made an exception with that crazy halfway switch thing Braun used. Was it an afterthought on Braun's part, did they just have 2-pos switches in stock or what is now anyone's guess. A 3-pos switch would not have detracted from the look of the radio and would have been less confusing to the user, IMO. Great job on the BT module, BTW. With a bit of stick-on velcro you could put it anywhere on the cabinet and then remove it when its no longer needed.
I think the reason was that they had lots of these switches in stock 😊 I just cannot understand the logic, and am hoping that someone will actually have the answer for us and add it to the comments.
That looks absolutely fabulous Manuel. Very professionally restored and at first I thought: where the h*ck did you get that back panel from? It looked really gorgeous and that's a first attempt? Congratulations my friend! Looking forward to that video. Cheers from the Netherlands.
😊 the first attempt resulted in a cloud of smoke that took a day to air out, because I set the power too high and the speed to slow 😊 This took quite a few tries 😞
@@electronicsoldandnew That's unfortunate but can happen. The nice back panel can still count as first attempt (product) imho and it looks really nice 👍🏻
Hi Manuel, as usual a nice job on that compact radio. I wondered, if you were to 3D print a thicker box for the BT board could you place a 5 pin plug (similar to the cardas M tone arm plugs) at the bottom adjacent to the board audio o/p point and create a couple of nodules at the top edge to coincide with the holes and their size in the back you made. With some earthed foil sreening in or on the back of the BT unit. You could then plug the box into the phono socket and back panel and not require the cable and also hide the unit on the back? It would cover some of the air holes and the Braun model label but shouldn't cause overheating. Btw just had my first go at smd construction and think I need to get a bench mounted magnifying aid to help my ageing eyes, if I am to continue with it. Struggled on with two pairs of glasses. Now making a filter trap for a hand held vacuum to find all the dropped components.😀
I guess that would work out quite well. However, the inside of these radios usually show signs of heat, so I’m a little reluctant to close off any holes. I’ve got one of those display microscopes, and that’s the only way I can actually do smd work at all.
Manuel back cove shows your great attention to detail, "bloody marvelous". With all the new toys you're acquiring how much space is left in the joint office/lab or for your wife hobbies? P.S. Amazon carries a right angle Din plug cable in case there is a clearance issue for your Bluetooth adapter.
Space is getting tight 😊 will have to consider buying the next door apartment to extent the “office” 😊 I saw that DIN plug, but I don’t think it’s going to be needed as I purposely want the BT module away from the radio itself.
Very nice. A very good idea to use the phono jack for Bluetooth. In my opinion the sound of this radio isn't that good. The amplifier is very simple and the speaker more on the cheap side. A Philetta sounds way better. This was typical for Braun products. An outstanding design paired with mediocror technic. I have a SK 2 so I can compare it to other old small radios of this time.
@@electronicsoldandnew Thx for your offer, Manuel! I’ll bring my Grundig 2001 with me. It has an issue with the dial cord, but for the rest it is in pristine condition, even after more than 50 years.
Some of the loveliest tea available in Europe is grown in the Azores. For over 200 years, cultivation has been undertaken. Gorreana Tea Company produces over 40 tonnes of Organic green and black teas per year on San Miguel, continuously since 1883. 🇵🇹
👍 I know ….. still can’t seem to take to it 😊 In fact. We (the Portuguese) were the ones who introduced it to English society, through Catherine of Bragança, so she was probably looking for another market to export to, rather than convert her own countrymen to enjoy it themselves 😊
@@electronicsoldandnew I myself take coffee. I drink a spearmint tea that my parents brought back from Portugal in the late 60s that grew in a small river near Beja, and that grows nicely here in Saskatchewan Canada. I did not that part about Queen Catherine..thanks for that!
You should read the book, “Portugal, the first global village”. It was written by a retired Times Reporter who moved to Portugal in the 70s, and lists numerous facts about our ancestors that most of us have no idea about. By the way, I believe an old Varsity (University of Natal, Durban - Electronics Engineering) friend of mine, Luis Rocha, lives (or lived) where you are. Now that would be a coincidence if it was someone you know or knew 😊

Hi Manuel, what a beautiful job. The dyeing trick with tea is really a great idea. Thank you very much for this beautiful video series about the SK25.
My pleasure
Beautiful! The pinnacle of industrial design! Timeless!
👍
Excellent!! Fantastic result!!!! That back panel is great and really nice work on the dial scale. Love the use of tea as an aging agent! 🙂
It’s a only good use for tea 😊 Sorry, couldn’t resist
I'm British and now I have been shown what has been causing my ageing all these years😉
😂 from the inside …
@@electronicsoldandnew Well, Manuel, I guess tea is, to use a British phrase, 'not your cup of tea'!! 😂(well, except when it comes to dial scales!)
😊
Loved the series. thanks for taking us along. That was bonkers brilliant. All the best mate.
Thank you 😊

The laser does need some practise 😊 You should have seen the first attempts 😊
Really nice restoration work
Thanks 👍
Excelente trabajo. Felicitaciones.
Gracias

😊 actually, the kitchen is where my wife has claimed it for 😊
Like the color👍
😊
In the classroom where I work we have a Glowforge Laser engraver ! I have a Philco flying wedge that is missing it's back that I plan to make a new one .
Should be easy … after a few attempts to get power/speed right. Good luck.

Definitely want to avoid impeding airflow
for doing fine body work and fill in the used to make a very fine filler called Nitrostan which might help out to make the cabinet work look smoother

I agree with you about the sound. I noticed that the speaker in this one is actually smaller than the sk2, so it’s even worse. Pity.
Nicely done, Manuel! BTW, how’s the weather in Madeira in september? We’d like to spend a vacation on your island.
At the moment it’s really great - about 24 degrees. And if you do get here, let me know. It would be a pleasure to have a coffee and chat with you.
