Grundig Yacht Boy 210 - 1970s Radio - Repair, Clean & Demo

- I found this early 1970s Grundig Yacht-Boy 210 radio at a flea market, the price was good, and I do like a good old Grundig radio, so I bought it. Unlike the other two Grundig radios I've featured on the channel, this one didn't need that much doing to it - the top of the ariel had been broken off so I've made a replacement top section, albeit still quite a bit shorter than it would have been originally, and the foam voice coil cover on the loudspeaker had perished so that was also replaced along with the foam gasket round the speaker. Other than that, it just needed a good clean and then it was ready to demonstrate. Although there's not so much repair work to do in this video, it is fairly representative of the condition in which many of these old radios will be found, just needing a little bit of TLC to get them back into action.

Great video, Tim.
As a child of the 80's and 90's radios were very much a part of my childhood and early work life before mp3 came around, so I've always loved these kinds of radios.
My grandad always had his 'wireless' in his shed and while I'm not sure if it was a Grundig, it was very much this style of radio.
I just noticed i hadn't watched your Concert Boy video from a few years ago so i checked that one out too🖖
Yeah, radio was very much a part of my life as a kid and at work, but then CDs and later iPods came along and somehow I stopped listening to the radio that much. It was only in the last few years that I rediscovered my love for the radio - not that I listen to it all the time like I used to, but it's kind of fun just twiddling the dial until I find something I like. Cheers for watching this one, and the old Concert Boy video - I cringe when I watch some of my earlier videos - they're still valid videos but I hadn't perfected my style back then - not that I've perfected it now, but hopefully it's slightly more relaxed!!!!
Great work. I used to love tuning around the short wave bands at night, that sound! Not the same now with 22 local wifi networks spewing interference at your radio!
Hi John, for me it's not just the local wifi, every single LED bulb with it's switch mode power supply is a nightmare for short wave - I have to resort to old filament bulbs!!! Short wave is such good fun
That's a great clean-up job! Also interesting to see all the countries/cities on the MW band
Yeah, radios from that time were fun, with lots of stuff on the dial that I never understood - even now I don't really pay attention to where the dial is, I just tune the radio until I find something I like. I stopped listening to the radio for many years, preferring to listen to CDs and the like that I'd bought, so it's been quite fun over the last few years re discovering radio - plus I've ended up with some cool old radios!!!
I'm sure they used to advertise these in Practical Wireless or Practical Electronics, back in the day. I certainly remember drooling over them. I think it was because they looked so neat and complicated, especially compared to the cheap rubbish that was otherwise advertised then. Whatever it was, I couldn't afford them.
I'd quite like to find an old advert for one of these, maybe I'll keep my eye open for old magazines like that. I couldn't believe it when I saw this radio for five pounds on a stall - I don't usually get lucky like that. Cheers for watching and pointing me towards possibly finding an old advert Simon.

New friend here. Wow, excellent radio repair tutorial video.
Cheers Juanita, glad you enjoyed the video - fixing old stuff like this is a very satisfying occupation.
Nice work mate... I am on the lookout for one of these at a decent price. I remember this radio, one of my friend's father had one of these and it sounded so good back then. Hence the thought of picking one up at a decent price. Awesome work on the restoration mate! W8BFO.
Cheers Will, they are rather lovely old items. I'd bet that if I went searching for one I'd only find bad examples for lots of money, I just got lucky, saw it, liked it, bought it. I tend to visit the odd flea market and that kind of thing - occasionally there are little gems like this. Hope you find a really cracking example just when you're not expecting it.
@@GrumpyTim Thanks mate, ex-pat here and as luck would have it, I found a pretty rough cosmetically challenged model on ebay but totally untouched internally this week, from a guy in Gloucester UK. Its making it way as we speak on a fast boat :) Its the 210N model. I was also able to pick up a copy of the service manual which is coming in from Germany so that's on its way also. Finding 210s here in the US is kind of like finding hens teeth in an archeological dig, if you know what I mean. I will take my time since I am in no rush to get it up and running and refurbished. Keep up the great work on the video's mate, they are both educational as well as entertaining. Just to add finally before jumping off here and on a conference call for work, (reminisce with me) I heard one of these sets back in the early 80s at a friends fathers garage just outside of York, his father built hot rods and dragsters, on the shelve in the garage was this Grundig playing music. I was so mesmerized as to the quality and how it looked I was kinda open mouthed when my friends father said "So you like my Grundig do you" I said it sounds amazing, he said yeah they are not cheap but made in Germany and built like a brick ****house. I swore that day I would own one. Well its been a long time coming but I loved the design of the radio not just the sound it was very unique for its time. Okay that was a bit of a trip down memory lane but I wanted to share why I wanted this specific radio. I even wrote down the name of the radio that day on my hand in pen and committed it to memory. The things that make us go bump.. take care mate and stay healthy and safe. Will check in from time to time as I have you subscribed now. Will in Sunny West Virginia.
Hi Will, that's a really nice story, I can see why you want that specific model, and great that you've got a service manual making it's way to you, that's always useful to have. Don't be surprised if it sounds a little fluffy/distorted when there's a lot of bass, I suspect the speakers get a bit floppy with age, but if you trim the bass back a bit or lower the volume they seem to clean up again. The sound of the old Grundig radios is really nice and not at all like that of a modern radio, it's somehow more mellow. Sometimes the majority of the music that's being played on the radio stations isn't exactly to my taste, but then I'll find a station playing something like Blondie (or whatever floats your boat) and I'm transported right back to a very happy time.......
I only get FM if I use that internal P3 battery connection on mine, but my speaker has gone now so not sure what to replace it with
Hi Monty, it could be that the AM tuner section is ker-put on your radio, or at least not working as it should. I guess if you can raid something else for a suitable speaker that you could transplant, I can't remember if it's an 8 ohm or 4 ohm speaker (or even something other than that). When I was a kid I used to just try whatever speaker I could find and if it worked, then I used it - I didn't get bogged down with things like the correct resistance and so on.
Good work. Also looks very good now.
Cheers Ben - it wasn't exactly a difficult fix on this one, but it's lovely to have it working. I wish I could travel back in time and give it to young GrumpyTim - I'd have been very excited to own a radio like this when I was a kid.
@@GrumpyTim Yes, I had valve radios with a wire hooked up to a washing line which had fantastic reception on short wave. I bet you would have loved it.
That sounds awesome Ben - perhaps I should rig myself up a better ariel for short wave - it wouldn't exactly be difficult - lots of fun to be had.
@@GrumpyTim I'd be interested to know.
I'll give it a go when I get a chance and report back to you Ben.
Muito boa tarde distinto amigo, tenho acompanhado seus vídeos, os quais trazem sempre belos rádios, como esses agora apresentados, que me candidato a compra de qualquer um deles, parabenizo-o por este vídeo, fico no aguardo aguardo de sua resposta, saudações.
Oi Decastrosilva, que bom que gostou desses rádios antigos, são muito divertidos. No momento não tenho nenhum à venda, estou me divertindo muito brincando com eles. Espero que você possa encontrar rádios semelhantes em lojas de segunda mão locais ou mercados de pulgas. Obrigado por assistir e comentar.
Hi Decastrosilva, glad you like these old radios, they're lots of fun. I haven't got any for sale at the moment, I'm having too much fun playing with them. Hope you can find similar radios in local second hand shops or flea markets. Thanks for watching and commenting.
I had one of these radios, long ago, in terrible condition. The only bit I've still got is the speaker. Could you (please) expand a bit on the voice coil cover? - the foam on mine is long gone too, so it appears I need a cover of some kind.
Hi Paul, I don't really have anything particularly scientific to say - I'm not sure if the original foam voice coil cover was a closed cell foam, in other words, sealing the area completely, or an open cell foam that could breath as the speaker moves - I suspect the former. I've noticed the speakers sounding more flabby when there is no voice coil cover in place, so my hunch is that the cover not only reduces dust ingress into the small gap between the magnet and the voice coil, but it also acts as a slight damper to excessive movement - after all, you have a small chamber which is sealed by the flexible foam, the only way for air to get in and out is through the small gap between the magnet and the voice coil, in other words, it will act like a very inefficient piston, giving a very slight damping effect. That could all be a load of rubbish, but replacing the voice coil with neoprene foam has made the speaker sound better each time I've done it. The neoprene foam I had been using was the backing from a very thin mouse mat that had delaminated itself, probably about 4mm thick, but I how keep neoprene foam in stock in various thicknesses (ebay) so I'll just use some of that next time. I glue it in carefully with EvoStick, applied carefully using the tip of a screwdriver rather than getting the tube anywhere near the speaker in case of major splodges.
