Great work Jon. The quality of this sort of equipment is way above modern kit so well worth saving. I've worked on numerous old clocks, some of value, most of little value but all worth saving. Best wishes, Stephen.
Thanks Stephen, it certainly is good quality, and it still looks very smart too. Cheers, Jon
Absolutely brilliant.....can't wait for you to join the "Repair Shop" team. Hope Mrs J is enjoying it.
Thanks Philip, not sure I am good enough to make it onto that team yet lol. Cheers, Jon
Gday Jon, you can’t beat old technology, built to last a lifetime, you did a great job mate, cheers
Thanks Matty, much appreciated mate. Cheers, Jon
Nice job, Jon. I was 10 in 1972, we had the same radio and another red one from Telefunken. We took those to the swimming pool in the summertime. Nice memories. Thanks for showing.👍🎶
My sister had one of these for Christmas 1973. I was going to thank you for bringing back good memories of listening to radio Caroline and tuning into the police band to try and find car chases, but damn, that was 50 years ago and now I just feel old. So, thanks for that.😉
Hi, thanks for the comment lol. I too remember radio Caroline and Atlantic 252, also doing the police thing lol. Cheers, Jon
I love my old 70’s radio!
Thanks Jon 🧡🏴
Thanks Dawny😇❤️
Great restore Jon. Good to see you getting into more electrical/electronics. It is never too late to learn new things.
Nice restoration Jon. I had a similar Grundig radio in the seventies. Wish I still had it now. Well done. Cheers Nobby
great one John, i tinker in the winter with electronics when i can’t get out on the bike or in the garage. There’s a channel called my mate vince who tries to fix Ebay spares only or Amazon returns. he is learning as he goes.
Hi Bill, thanks for the comment, I really enjoyed something different. Yeah, I have been watching Vince for a bit, very watchable videos. Cheers, Jon
Nice job Jon, making me want to get a classic radio 👴🏻👍
Thanks Terry, I thoroughly enjoyed this, something totally different (and I got to sit down while I did it😉). Cheers, Jon
Great result . They don't make them like that any more . Lol , now i might have to have a look at my old shop radio . It's sitting on top of the bin , went to turn it one & it wont turn on ! Only about 10 years old . 👍
Thanks Max. I am bloody useless with electronics, hated it at school, never understood it, but I am really enjoying dipping my toes in the water, you never know, maybe you can teach an old dog new tricks. Cheers, Jon
Tengo una de ellas, y la restauré, estaba en la basura, hace unos 7 años. Excelente Video. Saludos desde Temuco, Chile
Jon's work shop you are good at restoring antique radios and alignment of antique radios my friend
Back from Snowball Engineering. I would use a spray contact cleaner for those switches etc. Its amazing how much crap it can clean out and it dries in seconds.
Hi Bill, thanks for coming back lol. I will get some cleaner, I need to kit myself out with a few bits really if I am going to attack anything more taxing, but I am enjoying my new venture (even though I don't really understand it lol). Cheers, Jon
Stannic oxide is used for optically polishing acrylics etc. Eithe pitch polishing or a cotton cloth can be used with an aqueous slurry of stannic oxide. Its usually availble from Jewellery supplies vendors.
Hi Bruce, thanks for the comment and tip, that's a new one, never heard of that before, I will look into it. Cheers, Jon
Well done and have inspired me to try the same thing!
Ha Haaa mchiodox69, thanks for the comment. If you electrocute yourself, don't blame me. Glad I have given you inspiration, there was one on Ebay last week for a few quid, same model but description said working but struggling to pick up channels, might be worth a punt. Cheers, Jon
Hi Jon. Dad used to sell these in his Electrical shop back then. Not many sold due to the price. He sold more Perdio etc radio's of which were mainly made in Taiwan.
Nice reno though, looks good.
Steve.
Hi Steve, thanks for the comment. Yeah, radio gear was very expensive back then, these sort of sets only found their way into the well off houses for sure, but I guess, all that quality costs money which is why they survive 50 years on. Cheers, Jon
That was very nice Jon. Beautiful radio. I used to do a lot of this stuff in my teens. Wipes are good for cleaning. A 2" paint brush and some spray foam cleaner is very good for grilles etc. Switch cleaning/lube spray also good. As is air duster, or you can just use your compressor and make sure you don't blast it too hard, so long as its dry air. I won't go into any technical stuff just now as you will get to that later on. The only thing I would say is if you ever get any valve based kit, don't be tempted to plug it in. They have big capacitors that degrade so it'll probably just go bang. Have fun mate, its such a joy to hear old radios etc working again.
Thanks Carl, yep, been studying a bit on old caps, I inspected the caps in this and they all looked and measured OK. It might seem bonkers doing all the work before you know if it even works but that makes sense to me. Cheers, Jon
@@jonsworkshop You can "reform" capacitors that have degraded over time. Often not worth it though. Really large ones, even modern ones need to be reformed if they are in storage for long periods. It's an interesting string to add to your bow, the electronics. It's helped me enormously over the years.
Rite Jon, Great repair. Another rabbit hole I fell into, the only advice I can give is never plug valve gear be it amps, radios or old test equipment into the mains to see if they work before giving them a good look over and then use a dim bulb tester or a variac! Micro mesh is a very good abrasive paper/cloth to use, used to use it to polish my corian pens, comes in stupidly fine grades! As always Dude stay safe n well. TFS, GB :)
Thanks Graeme, I will look up micro mesh, never heard of it before. Cheers, Jon
Sounds great well done
Thanks Steve
Hiya Jon maybe as a point of interest, the little stickers on the top were from the bbc sometime in the seventies, if memory serves me. they supplied them when they had a big change over of their frequencies. I was only a kid then, but I remember my dad put them on our stereogram, now there's a piece of equipment! still in their loft to this day😁
Hi Paul, thanks for the comment. Yup, you are similar age to me, I also remember them, don't think my parents had any but I remember seeing them on extended family's gear and feeling cheated we didn't have any lol. Cheers, Jon
@@jonsworkshopThe frequencies changed on the 23rd November 1978
So, now you have a "made in Germany" radio that speakes... English :)
And your point on restoration videos at 03:22 was spot on.
Thanks Rusti, I don't know if you spotted it, but the Autosol polish I used said 'Made in Germany' on the tube, I very nearly called it out for your benefit lol. Those fake Resto videos are just trash, the worrying thing is millions of people seem to like them...... what does that tell you? Cheers, Jon
good video Jon
Hi Jon. That brought back some memories. I spent a fair bit of my teens fixing things like that for my parents and grandparents. It was more running repairs than restoration, but I suppose it was nearly 30 years ago! I would suggest getting some solder wick (also called desolder braid) for tidying up after desoldering parts. It's very good to have on hand, and compliments a solder sucker. I have a few electronics beginners books if you're interested?
Sorry Jon, started watching and then got a notification that Snowball Engineerings new plasma table had arrived. I will come back to you later.
used to repair plenty of those as the teenager, was my hobby :D
I love the old radios have several of my own 1960's to 1970 and they play better then the Chinese crap. Great restore of a classic peace of history.
Thanks RB, something very satisfying about it all that is hard to put into words! Cheers, Jon
Interesting !
I agree with you. The older stuff is much better.
eyup Jon
well done, i'm a electronics dinosaur too!🤣🤣 i like anything retro, you can't beat it, when things were made with lasting and repairable qualities.
I thought i was going to learn something about changing transistors, 🤣🤣 or are you saving that till next time👍👍👍👍👍👍
keep up the good work.
Hi Kev, thanks for the comment. Lol, baby steps. It's funny, I used to hate electronics at school, never understood it. I am now really interested in it having dipped my toes in the water. Cheers, Jon
used isopropylene alcohol to remove the sticky surface on a camera body , removed the rubberized coating (thats the stuff that decomposes and get sticky over time) , so dont use that stuff too vigorously as it can melt some plastics
one trick for the see through plastics (and car lights too btw) is put them in the dishwasher , they come out like new , just dont tell the wife
Hi Watahyahknow, thanks for the comment. Yeah, IPA needs careful use but it is a great liquid to have around. Lol, dishwasher, what's one of them? 😂😂. Cheers, Jon
@@jonsworkshop you too huh , im my own dishwasher just push a brush in my hand and stand me in front of the sink
Another good job well done. Nice quality sound, unfortunately, most radio is moving to inferior (in some cases) DAB. A wee tip or finer polishing is toothpaste but finish would probably be limited but the type of cloth used (microfibre might be best)
Hi Pakrattuk, thanks for the comment and tip, yes, I need to get myself some microfiber cloths for the workshop. Cheers, Jon
Hey Jon, thanks for yet another informative vid!! Um, I've heard if you slightly heat the plastic, it re-releases oil in the plastic (plexiglass) and brings back the natural shine? Nonetheless, great work!! Hope your Wife loves it too!! Cheers, Mate.....
Hi Markus, thanks for the comment mate, I will remember this for future projects and give it a try. Hope you are well. Cheers, Jon
Grundig TV s were all the go in Australia in the 70s . That Autsol is as good as Vegemite, good luck with the Electronics i always have trouble with drawings that had Squiggily lines .
Kit from down under
Hi Kit, thanks for the comment, spot on. I might pass on the 'Autosol Sandwich' next time I am listening to Men at Work though😂😂😂. Cheers, Jon
GDR & FDR equipment were always well made, but the materials used differed considerably, i had both East and West German motorcycles.
Did you find any micro film or micro dots Jon.
I recommend Mr Carlsons Lab on YT, brilliant old electronic repairs.
Love the electro mechanical devices on this era of equipment.
Nice project.
Thanks John, I didn't see any but then again I don't know what I am looking for lol. I will check Mr Carson out. Cheers, Jon
Knit 2, purl 1, stitch, would you tune into the light programme please?
Lol Choroidal, I knew someone might pick up on the knitting reference. Hope you are well mate. Cheers, Jon
Dang it, now I know where to send dozens of my old radios and shot cars to get made over, hehe! Bear
Hi Bear, thanks for the comment. Lol, don't send anything electrical that you want to see working again 🤣🤣. Look after yourself buddy. Cheers, Jon
The thought was funny, but scary to think I still have things wasting space and collecting dust from the 1970's 😞
I have Grundig Melody Boy 1000, i love sound that FM radio
Cracker tray? Looks more like Chocolate Royals to me! 😉
Lol, thanks for the comment Phil. Cheers, Jon
Jon's work shop my hobbies are painting pictures 🖼 and listening to shortwave and ssb iam thinking about getting my Grms license
Jon's work shop i have a vintage zenith Trans oceanic transistor shortwave receiver I want to restore it let me no ware I can get Russian germanium transistors?😮😮
