Come on people! Become a subscriber! David Tipron is one of the BEST in restoration!!! He's so thorough in his work, and a nice guy.
Haha.. thanks pi-duino 😄
My sentiments exactly!!
You forgot to mention how entertaining he is as well. Although this video is sadly lacking in Dad or Grandpa jokes this week
I am already subbed to Dave and I agree he is both methodical as well as adopting practical approaches to all repairs/restores in his videos. He doesn't give up when something goes a bit wrong.
People don't care about old radios, they want to watch car crashing, hot knifes burning watermelon, etc...😁
Yup, he deserves more than 11K subscribers! Come on folks!! Well done, as usual, David!
Thanks Dave, 11k might be about the limit, although I said that at 1k 😄
@@DavidTipton101 Well, from the point of view of the electronics repair you may be right. But your ingenuity and attention to detail in approaching the repair of plastics, wood, rubbers, brackets, perishing insulation and anything else you lay your hands on, is worth watching just for those aspects too! Your videos are incredibly satisfying. I will say, though, that I am the kind of guy who hates to throw things away that could be refurbished. I don't belong to this throw-away world! Neither do you, clearly!
Terrific! I love old consoles. Really fun to watch you perform your magic. Thanks Sir David!
Thanks for watching John 😀
Amazing. Its like a foreign language but I can't stop watching 😎👍
It's foreign to me too sometimes Ashley 😀 Thanks.
What a quality unit, looks and sounds great! well done! Cheers
Thanks Bruce 😀
That "quality unit" as you call it was not cheap in those days. Germany was just barely recovering from WWII and the Wirtschaftswunder had brought prosperity to a great deal of Germans. The better off could afford to buy such cabinets while common people bought a small transistor radio. Considering its age this combination is in a really good state also because it was Made in Germany.
i really like the effect of the new scale background, so fresh/bright looking :-D
i don't think it would look as good as that from new.
It's nice to see you have an easyer time fixing a radio, not a pain in the bum in comparison to some of the others you have restored.
You and your neat bracket making, so many times you have made them look original.
I appreciate nicely hand made parts, it's a skill that less and less people have :-(.
If the radio was case less, i bet that chassis would look nice in a normal tabletop radio case.
Imagination working for no reason :-D
Thanks zx8401ztv. This was an easy fix, almost disappointing to some degree. I wonder if they used this chassis in a table top version 🙂
Thanks for posting this repair was fun , The fiddling was what I do , when the project doesn’t run !
Thanks Keith 😀
That’s a good looking cabinet and looking forward to the rest of the videos.
Looking forward to this one, David! A small note to all viewers, when handling a Grundig chasis, be careful of the selenium rectifier on the side of it. I got my first good B Plus jolt grabbing one and learned the hard way! The most fascinating thing for me, David is how you rarely run into an issue you can't find a work around for. Hats off!
Thanks John. There seemed to be little concern about hanging high voltage connections on the outside of these early radios, grabbing the live chasses would have been a bit of a wake up 😮
Your right John! David will either find or make a way to make it work. He will 3D print it, manufacture it, or scare it into working. ;-)
The solutions he comes up with are so artistic, creative, and downright genius!
Another lovely job, as always.
Thank you robbyxp1 🙂
I love these Grundigs. Wonderful workmanship, elegant design, beautiful sound quality. Thank you for sharing this.
Thanks 1967, I can't wait to hear it either. My pleasure 😊
Great series on the Grundig Torento! this helped me immensely when I needed to fix my 1964 Grundig Mandello b/u, especially the 1025 Philips record changer. Thank You,
David!
That's good to hear Kevin, glad to have helped, cheers 👍🙂
Really enjoyed it David, and looking forward to the next part!
Thanks Bob 🙂
Good do, always a great watch good start to the weekend, you have befuddled my brain and put a smile on my face, looking forward to the next episode, big love, and a big thanks
Thanks Martin. my pleasure 🙂
You know it's going to be a good day when you start it bright and early with one of Dave's amazing videos while having breakfast. Great great work as usual my friend, can't wait to see part 2. Have a great day mate :-)
Hi Sarge, thanks mate 👍😄
Your approach to repairs is absolutely outstanding David. Fun to watch your work. After doing a lot of repairs and restores , you really have got the hang of it!
Thank you Steve. I'm getting better and I keep learning, that's the fun part 😀
I love these Gundig radios and to still be working after all this time is a credit to the manufacture. Great work Dave and look forward to part two.
Thanks Stephen 🙂
It's your attention to detail that makes your restorations a pleasure to watch. Even though your attempt at creating a new litz coil wasn't needed, the fact that you even thought about leaves the rest of us in the shade! Awesome!
Thank you SoRTs6233, it pays to be resourceful even if it is a failure 😄
Very nice sleuthing and cleanup. Thanks for the look.
Thanks John 🙂
I am loving this restoration. Creating your own Litz wire - man you are a genius. Keep up the good work!
Thanks Martin, my Litz wire technique needs more work 😄
Always nice to hear to hear your accent Dave makes a pleasant change from humourless American ramble......
Hi Philip, I don't have an accent, everybody else has 😉 Thanks Philip.
David you've done a great job as usual ,and I enjoy your restorations
Sheldon , Los Angeles
Thank you Sheldon in the City of Angles 😀
Looking good David. Can't wait to see it finished. Joe
Hi Joe thanks. It will be a good piece when it finished 😀
Nice job. Thanks David! John
Thank you John 🙂
Excellent as always Dave! Whether you needed it or not it was very cool watching you make that multi-strand wire. Nice playing Gift sir!
Hi Gregg, thank you. The Litz wire was a failure, it has to be laid in a particular way for it to work but a bit of fun. Thanks for having a look Gregg 👍😀
I'm always impressed with your work keep it up 💯
Hi خالد عطايا thank you 👍🙂
Metal rescue sounds cool. Many thanks for the trick. New to find this and send it to France 😊👍👍👍
Thanks cfpradio creations fred et pierre, I hope you can get something similar in France 🙂
Excellent going there, David, that was a fast and efficient, no frills resto. Impressive..
Thanks Blitz 😀
A perfectionist at work! 👍
Thank you Harry 😃
Greetings from England! Nice restoration as usual. I had a radigram with a similar chassis but with FM and multiplex facilities - yours looks like the same chassis pressing but without the "FM" bits. They sound very good indeed when restored. Always a pleasure to watch your videos.
Hi Robert, thank you. The chassis has all the facilities for the FM module but not fitted when it was exported to Australia, we didn't get FM for another 10 years after this was built. I hope it sounds good, the speakers are big enough 😀
Just great to watch and learn.
Thank you Herman 😀
Another great video David. Looking forward to part 2. That is a good looking radiogram. When they are working well they sound good .Best wishes Terry uk 🇬🇧 👍.
Hi Terry, thanks. I'm looking forward to hearing it when I get it assembled 👍😀
Great job, as always, Dave! DIY Litz wire! Even your failures are educational and fun. It’s always good to have a “parts set!”
Thanks Super Het. It's even better when you know you have it 😄
Thanks David! Great job and really inspiring.
Thank you Leif 😀
Thank you David! Loved how you made a new coil, even though it didn't work as planned don't know if I would have had the courage to try. Good job.
Excellent video well done Mr Tipton very informative article thanks 🇬🇧🇬🇧🇬🇧🇬🇧🇬🇧🇬🇧🇬🇧
Thank you Phil 🦘🦘🦘🙂
Excellent. Till next week! 😊👍
Next week I hope, thanks Pauline 🙂
Back in the late 60s I built a stereo amplifier from a circuit in Practical Wireless which used the ECLL800 output valve (two push-pull output valves in one bottle, a little like 2 x EL84s). I remember when I went to my local electronics shop the guy refused to believe there was such a valve and insisted I needed an ECL80. Only when I went back and showed him the article did he do some research and grudgingly admit he was wrong. It continued to be a bit of an obscurity and I'm delighted to see it again in this Grundig set.
Haha... I can imagine him not knowing about it, I think they had a limited application life and were soon to be replaced by transistors. Two push-pull and the phase inverter as well, very neat 🙂
Great to see this - a Grundig has been on my workbench for weeks and I'm down to the last couple of problems... I think. I didn't leave any of those pink paper "ERO" caps in mine, I'm a worry wart! Your videos are excellent, I've learned a lot and gained confidence. Rectifier is next so your info is timely. Best to you
Hi Mark, I hope your Grundig works well when you finish it. I left the ERO caps in after I declared they were going but I tested them and they were spot on, they are only a few hundred pF. I may still change them due to public pressure 😄 Cheers!
Hi David another good video, the experiment with the LITZ wire was well worth the doing, it's given me some headaches in the past, looking forward the the next episode thanks again David.
Thank you Lee 😀
Hi David Just found your new video. Once again great work, Looking forward to part 2.
Had the Covid jab and went down like a bag of spuds to keep it clean.
Had a real bad reaction but it seems to be getting better.
I'm well enough to get on RUclips and look at great videos from you.
Keep up the good work, enjoy the coffee.
Regards
Ernie
Hi Ernie, thank you. I also had the jab and like you went down like a bag of spuds. In the video I put out before this one in the first half you could tell I wasn't well, I could do a bit of work then go to bed for an hour and do some more later. A small price to pay if it works. Thanks for the coffee ☕👍🙂
Amazing, I've never known anyone to create their own Litz wire. Marvelous job my friend.
Its probably how it was done in the factory.
Hi Johnny, I got the Litz wire all wrong, maybe next time 🙂
Lovely job David, so interesting and tech explanations and information..Fab, and I'm learning all the time. Thank you for sharing..Ed..uk..😀
Thank you Ed, my pleasure 👍😀

Ha ha the lipstick antenna sarger Reminds me of the old pantomime" Ten thousand people" saying ITS BEHIND YOU .first class post David 👍👍
I could hear them yelling too but took no notice, thanks Shaun 😄
Hi Dave. Great job. A couple of things I'd like to mention. You can't simply determine the dissipation of that resistor by measuring the average D.C. voltage across it, as the current waveform is in the form of pulses. To do that correctly, you need a true RMS meter that also takes into account any D.C. component. The actual dissipation will be considerably more that an average D.C. voltage would suggest. Also, I can suggest why your home made "litz" wire didn't work too well. In actual litz wire, the strands are arranged such that each one is in places running along the surface of the bundle, and in other places more towards the centre. It is to minimize the "skin" effect, of a wire carrying RF current. I hope that helps. 😊
does that explain the sensititivity (or lack of?) , so factory would have woven with some kind of moving shuttle
Hi Stuart, thank you. Good point, I have a true RMS meter but whether it takes into account the DC component I don't know. I can still touch the resistor without the heatsink so it's running cool enough.
My faux Litz wire was a hasty decision and I later realised that is isn't twisted and as you say it's laid in a specific way. There is a Wikipedia article on it which I will read at some point. Thanks again Stuart 👍🙂
You are more creative with each new video David. Walt in Miami
Hi Walt, thank you 🙂
That looks like a great piece of furniture for your house - wife willing :-)))) Have you ask Manuel Caldeira if he has a schematic or knows a source ? Manuel lives and breathes Sabas and Grundigs on his channel.
Hi Paul, I have a spot for it... wife conceding. I now have the schematic for the radio, a bit late though 😄
Looking forward to the turntable and cabinet resto. In your hands I'm sure it will come up better than new.
Thanks Ian, fingers crossed 🤞🙂
Great radio you've got David!
The amp is stereo for the turntable and (probably) the tape recorder.
One tip: sometimes the polystyrene capacitors can fail, the failure is that they get intermittent (the leads will lose the contact with the foil).
I had one capacitor like that that was intermittently killing one of the shortwave bands, moving it slightly would bring the band back.
It is always great to see how you come up with solutions to make things look neat, Love your videos!
Best Regards,
Moshe.
Thanks Moshe. Yes, the tape input is stereo too. Thanks for the tip with the capacitors, I'll be weary 🙂
Funny what flashes through one's mind when you see a video such as this posted. First, of course is joy at a new video, it always seems as though your video's are almost like having coffee with a friend, then there is the familiarity with the name, David, ("David and Goliath" cartoons on Sunday Morning here in the US sponsored by the Lutheran Church - A boy and his dog story in puppet form teaching not just religion, but living the just and good life,) Davy Jones (Singer in the 60's) Dave Nelson, a buddy of mine in Vietnam (wonder what ever became of him?) and many other David's that I got to know in my 70 years haunting this old earth of ours. Thanks a million for giving me something to eat up some of the uncountable hours that God keeps piling on my plate to be spent trying to make the world a bit better place.
I'm glad you get so much from my videos Jerry and these comments help me keep in touch with the folks that watch them, therapy in both directions. David is a common name, where I used to work there were about 100 engineers in four crews, there were almost enough Davids to make up a crew, just short of 25 if I remember. Thanks Jerry 🙂
I watched "Davy and Goliath." I am Lutheran, but it wasn't until much later that I learned that the church sponsored it.
Hi David. That is a really nice project you have there probably from around 1962/65. In the UK we got the FM version and my late uncle had one, and the sound was superb. The auto record deck was rubbish when playing recordings with plenty of bass in the music. I put a Garrard sp25 into my uncle's radiogram and it performed very well. My school never did work out where their turntable went, that was back in the 70s. Look forward to seeing the next episode. Cheers Chris.
Hi Chris, thank you. I haven't tried the turntable for sound but it is a very basic unit made by Philips so it wouldn't supprise me if the reproduction was also basic. I wonder if the school is still looking for their turntable 🤔🙂
@@DavidTipton101 Hello again. I forgot to say that the old turntable on my uncles gram used to skip badly when playing recordings with a lot of bass or drums. I can't remember who made the actual turntable, but it wasn't very good. My old school was demolished about 20 years ago so I think that I'm safe now ha ha. Hopefully yours will turn out OK. Cheers Chris.
@@chrisclark6192 I hope mine doesn't do that 😮
Another nice radio adventure Dave! I might have to try some of that Metal Rescue that doesn't effect the paint that isn't there!! 😉🤣 Nah, seriously, it does look a good product! 👍🙂
Hi Chris, haha... it looked like paint till I cleaned it, oh well. Thanks 👍😀
Good morning David. I think with all of these radios you may need a bigger house. 😆 great show.
Hi Terry, yep it's just about full. Thanks 😀
Well done! Interesting!
Thank you Michael 😀
Sad to say :-/, but.... a wonderful video as "usual" ;-) . I like the way you approach things .

Gracias por excelente video.
Un Cordial Saludo.
Gracias por ver a Juan 🙂
It's been an extremely busy few weeks. Time for me to binge watch me some Dave's Radio Adventures!
Haha... thanks Rick E 🙂
Huh, the Germans would have us think that they're always "alles in ordnung" But Fritz und Hans must have assembled that set on a Monday morning or a Friday evening and been dreaming of the bier hall to have missed soldering the speaker contacts and let that giant solder blob short get by QC. It's a lovely console set, even before your repairs. I'm looking forward to seeing it all done!
There were inspection paint marks all over the set, it got through somehow and no one ever noticed. I'll be happy when it's done too. Thanks Dennis 🙂
What a beautiful, It is really cool .. 😊 ..
Thanks Mohammad 🙂
I keep a bad 7 and 9 pin tube that i have added some file marks to. I spray the tube pins with DeOxit and work that around in the dirty tune socket to clean it. Works really well cleaning stubborn tube sockets.
Hi Glen, good idea. I have been using dental picks which work well too. Thanks 👍🙂
David, that kind of a chassis surface gave me a problem with a tube socket. The sockets metal rings are also connecting ground to different connections. The FM first stage/oscillator tube had an intermittent problem with shifting frequency 1 MHz. ALTHOUGH the tube socket connection had also its own ground with a firm wire to the tuning capacitor ground, the chassis or its layer was oxidated (not visible) between the chassis and the socket (connected with the hollow rivets). Somehow a ground loop was made by that, and disturbed the FM oscillator. I had to drill it out, put in a screw and nut, and after that SOLDER it all solid to the chassis before I got the FM stable. When I heard your intermittent pre-amp problem I thought of that first.
Hi Erik, that's good point. Thank you for taking the time to highlight it, it's now in my non volatile memory, cheers 👍😀
Very nice set! I do spot two paper caps, or maybe three - the two red ERO 100 next to the electrolytic you replaced and possibly one in the switch enclosure (far right).
I'm really looking forward to the next part!
Thanks Ragnar8504. The two ERO caps aren't paper as far as I can tell but I might change them, it's been playing on my mind. I'll have a look for the third one you mentioned, thanks 🙂
@@DavidTipton101 ERO100 are paper caps that had the ends dipped in some kind of epoxy, which is quite deceiving but doesn't improve matters much. Kondur (a manufacturer I know absolutely nothing about, except that Philips Austria used their products in many of their radios) did the same thing.
ERO100, Eroid (both manufactured by Roederstein), brown WIMA Tropydur "cough drops", colourful Kondur rolls and blocks and the even brighter, resin-coated Czeija & Niessl capacitors are the ones I throw out immediately in European radios, similar to red and orange Roederstein and yellow or orange Frako electrolytics in newer equipment (70s through early 90s). Blue Philips electrolytics don't have the best reputation either but at least they don't usually short out. Those smaller than 220 µF do tend to drift a lot.
I don't have a lot of experience with British radios but the few Hunts and Dubillier capacitors I've had were just as bad as the list above, although they were completely encapsulated in some kind of black (Hunts) or blue (Dubillier) plastic.
@@Ragnar8504 Ok, thanks Ragnar8504. I will revisit the caps in question 🙂
You could have just remade that coil with... Oh never mind. 😆
Great video as usual. Thanks for posting!
Haha... thanks Jac 👍😀
David her zaman ki gibi muhteşem devamını bekliyorum
teşekkür ederim Mutlu 😀
I owned that Grundig! It was my Ukrainian Grandfathers, many beautiful memories to listening records on a Sunday afternoon.
Hello Yngve, yours might have FM if it's the European version. Thanks Yngve 🙂
It must have been back in 1972, my Army Unit had just been ordered to transfer from our mountain/forest training area around Fort Lewis in Washington State to Desert warfare training at a base called Fort Bliss Texas. My wonderful wife was pregnant with our daughter at the time, when I notified my commander, he gave me the choice. I could transfer to another unit in Fort Lewis, some artillery outfit I believe it was, or go with the Advanced Party for our Unit moving out in just 2 weeks. A brief conversating with my wonderful wife and we decided to go to Fort Bliss. That was a move that I indeed never regretted as we fell in love with the Desert Southwest of these United States! When I got there, the base had been pretty empty for several years. The buildings had suffered for their lack of maintance, so first off we became a cleaning crew. When off duty, my wife and I began exploring the pawn shops that surrounded the Fort. They too had suffered with the movement of troops so their prices were quite low for a hawk shop. That was when I first found Grundig. I purchased a Grundig Reel to Reel recorder/player. It was very high quality but didn't much look like the Teac that I had over in Vietnam. The sound it put out though was fabulous, and I fell in love with that brand name. All while I served in the Army, Grundig was on my shopping list in every pawn shop and thrift store I could find. Over the years many units passed through my hands but at the end of my career, which came while I was out Recruiting in Minnesota I had resold every Grundig unit I ever had. It wasn't until a few years back, perhaps 5 or 6, I don't recall the exact date that Ebay had a nice little Grundig AM/FM/SW travelers radio. It had suffered puppy damage to the back, so the battery cover was gone and a pop out lean support was also filled with puppy teeth marks. I bid on it, and my opening bid brought it home. I found the necessary parts to bring her back into shape and she has served me well. I guess I should say she served my wonderful will well for many years, as once I had it put together, she saw it and instantly fell for it. She had it in her computer desk and used it every day to keep up with the local news on our local AM Station. Now that she has passed on, I retrieved it and cleaned all the grease from it's skin, as she did take it with her to the kitchen many days, it still works like new. The only thing that has failed is the bulb for the dial light. I removed the back cover but could not get to it, and not wanting to do more damage, I simply put it back together and now it rests on my desk, I keep it in the nylon case that it came in, it too has the Grundig label so I am quite sure it is proper for that set. My biggest disappointment, however on receiving it was the label: DESIGNED IN USA> ASSEMBLED IN CHINA! It is still a great little radio and I would not give it up but I miss that MADE IN GERMANY that used to adorn such sets.
A wonderful living with Grundig story Jerry. It's a pity it's only a brand name for Chinese goods but maybe some of the Grundig quality rubbed off on your set. Thanks Jerry 🙂
Hard to imagine that the Grundig company, " the largest radio factory in Europe" it says on the back, is nothing but a brand name today. Superb radio. Making the Linz wire may have been an unnecessary task, but as always a joy to see your problem solving skills at work. Oh and a try from the NRL 👍😁
Hi Ken, the drop in quality is evident in this set as Grundig tried to keep ahead, not so much in the user experience but the cabinet and record player are poor as is the finish on the chassis, the componentry is still good and I bet it will sound good too. It wasn't a good game, my team got a hiding 😄
@@DavidTipton101 looking forward to seeing video 2. We get some of the NRL live here and I watch what I can, makes up for Leeds Rhino's, not having the success we once enjoyed 😂

@@kensherwood4866 My Broncos team and cellar dwellers at the moment 😀
That's a lovely bit of gear, I was suprised by how few replacement parts you had to fit on the chassis. It's a Grundig though, it wasn't cheap and they didn't use rubbish parts.
HI Paul, yep, it worked pretty much out of the box, the components seemed to be of good quality 🙂
Strange how the cabinet looks realy nice shape , but the radio chassis is all corroded, I know you will make the cabinet look better than new great job as always ..
Hi Paul, that crossed my mind too, the cabinet is chipboard but it seems to be still solid, it has been stored somewhere damp. Thanks Paul 🙂
Love Grundig radios. piano keys and all. If I were closer I'd ship you the Satellit 2000 that's gathering dust upstairs, including the sideband oscillator. Sadly, it'd cost a mint. That Mr Clean jingle was quite a touch. Another Tipton Triumph! (When I had the 2000 restored around 15 years ago it cost me £300> And now it's gone wonky on me again.)
I have a soft spot for European radios especially German ones, they are so thoroughly designed. Shipping is prohibitive especially large items unfortunately. Sorry your 2000 is wonky, it's hard to find people to fix them these days 🤔
@@DavidTipton101 I took it to a guy in far West London trading as London Sounds. He did a good job but I think that, since I didn't use it regularly, it fell into disrepair again. I bought it from a German guy who swore that it was in working order, but the SW "cylinder" was out of place and didn't turn, and the meter had been almost ruined. Oh well, there's hardly anything left to listen to on shortwave that isn't available on the internet.
@@chrishansen724 That's true but it's not the same as tuning a SW radio 🙂
You Beauty! Friday night Dave. Bit of a German theme tonight Dave's doing a Grundig and just sold 2 NOS Telefunken EL34s on the Bay.
Thanks A Last, that is a German theme 😀
5:50 Those tubes look so unassuming for $100, I'd never have guessed that each contained a whole push-pull stage, complete with inverter. Good thing they were OK. I'm surprised they'd bother deleting FM from a set this nice; it must have been on the way over there by the mid 1960s. Nice work; I hope the turntable goes as well.
Yeah, they are getting hard to get is the problem. We didn't get FM until 1975 in Oz, they probably hadn't even settled on a system when this radio was built 🙄
Hi. Great work! Very nice radio. Those chassis used to be made of zinc plated steel, so after 50 + years, moisture and acidity have wiped that coating off on many of them. It would have been interesting to measure the inductance of your home-made antenna coil against the original Grundig one. Good luck.
P.S.: Polka animé? That’s a new one, I guess...
Hi John, thanks. I don't know what was on this chassis, it had been removed so thoroughly I couldn't believe it ever had a coating on it except for traces on the sides and around some components. I should have measured the inductance when I found the second coil, I don't think it would have been close. Haha... that was the closest I could get to a German polka dancer 😄
also since it doesnt have FM you should add a input for a bluetooth dongle or whatever you want to plug into it.
Yep, I could, I'll think about it 👍😀
A Grundig without FM! For me as a German unbelievable. The chassis looks like it's also used with the FM-part in Germany,
I've also wondered about the versions that didn't have the whole 88-108 band; maybe the local regulations prohibited sets that went beyond what was authorized for broadcasting at the time.
It was an export model to Australia, we didn't have FM till1975 so there was no need to fit it. It would be the same chassis as the FM model 🙂
@@pcno2832 That was in Germany the case, in the 1950s it was only 87.5-100, later to 104 and only around 1980 up to 108. But the first stations in these frequencies started in the late 1980s.
Old dirty switches seem to cause about 90 percent of the crackling noise on a radio. But tis always best to check everything and leave nothing to chance like you do David.
The switches on these sets should be the first thing I attend too LUCKYLARRY, although I didn't expect the symptom I had from them. Thanks 😊
Very nice console. (To answer the lady's question, no I can't picture James Bond driving an electric car with an automatic transmission.)
Hi Wayne, he might have to if he wants to remain carbon neutral, I can see him in a Tesla 😀
@@DavidTipton101 Most electric transmissions on power to weight far surpass petrol for acceleration. strictly the motors dont need a geared transmission, but fit or keep one in and its even more fun(basically saves the back axle, unless you fit individual motors to each wheel and have more fun. The modern multi pole , wound and high magnetic metals are an improvement on the milk float era. Even the steam wagons (and cars from the 1900s) could run along at 60mph+ which is scary for their weight distribution. What is needed on the electric cars are additional speakers and tone generators to overcome the whine of electrics and replace with an audio of the petrol / turbo roar as the accelerator pedal is moved.
It's not about efficiency. If it were, 007 wouldn't drink a Martini, "shaken, not stirred" He'd chug grain alcohol.
@@highpath4776 Maybe James could make car noises with his mouth while he chases SMERSH 😉
Dave thought I'd pass on to you a neat little way I've just found ( about 10 minutes ago) of bring up bakerlite .Its Kiwi ( no pun intended) shine and protect shoe dye .the one with the liquid inside and the soft foam applicator. I used very fine wire wool to remove the grime .l applied the shoe dye .let it dry then buff it out .I got a really nice shine. Allso tryed the black dye on the vinyl on my (yacht boy) radio I've just finished I used a cloth to work it in Works a treat Regards shaun
Hi Shaun, Thank you for the tip. Some folks in the group have been experimenting with shoe polish but I don't think it was the liquid type. I assume you are using brown? 👍🙂
@@DavidTipton101 yes brown I found it actually soaks in to the bakerlite
I dont know as yet but it seems to react with the bakerlite because you can smell that pungent odour but it disappears after awhile. Allso there are range of colours and I found you can blend them as well .but how about this David .I have an old signal generator I am restoring and the front panel is aluminium and has a sort of mottled effect and its black . I normally would re spray it . But I thought I would experiment with the dye .I scuffed it with scotch bright used the dye .let it dry then sprayed it with lacquer left it until next morning went to have a look thinking its probably a right mess . It looks bl##dy brilliant. And it retained its mottled look . But if i I had re sprayed it it you would lose the effect iam now experimenting on different things . Early days yet. I've had a few disasters. But all in all I think for our passion for vintage Equipment it could be just what we are looking for .and its ready available in super markets. Ps dont buy the cheap stuff it doesn't work as well . I will let you know how things progress. " Umm I wonder if it will work on my grey hair " All the best mate regards from over the pond.
@@shaunsiz.itsbetterbytube2858 Thanks for letting me know Shaun, any info is appreciated.
@@DavidTipton101 try it on a scrap bit of bakerlite first .I have only just started experimenting with the dye so early days
Hi Dave,
Lovely radiogram you got there! Grundig manufactured some superb radios, televisions, and tape recorders in their day. I’m not surprised most, if not all the resistors measure within spec’. It’s quite possible the West German component manufacturers, as well as the radio and television producers, used the finest of materials. My guess is, when comparing West German manufactured stuff of the 1950s, and 60s with GDR manufactured stuff of that same period, there was barely no contest - West German stuff was always far superior. I remember a few GDR manufactured radios and televisions of the late 1960s: despite being reasonably well built, they generally looked as atrocious as they were reliable - probably the reason they were, along with virtually all Soviet manufactured stuff, “Cheep ‘n’ nasty”.
What is that signal, or functions generator you use for realignment purposes? It looks to be small but it appears to do a brilliant job!
Looking forward to Part 2 my friend.
All the best from Phil.
Hi Phil, thank you. They all tested very close to spec, within a few percent. I was desperate to find a crook one but no luck. Even the ERO caps were perfect. The generator is a kit from Silicon Chip magazine, I believe there is a sister magazine in the UK with the same project. It's made specifically for AM radio alignment and also features a built it mini oscilloscope to show the curve and readout the frequencies but I rarely use that. Cheers Phil, take care. Here is the link to the first page of the kit article: www.siliconchip.com.au/Issue/2017/September
Good to see you restoring a Grundig. It's a pity that one has no FM. I have noticed that you guys over there seem to have a very active AM band, contrary to us here, so it should become quite useful.
PS. I would like to discuss something with you, but don't have your email. Could you email me? My address is on the 'about' page of my channel. Thanks.
Thanks Manuel, the lack of FM is not a big deal for us as we listen to AM anyway but I was disappointed when it didn't have it. I will flash off an email, I hope I'm not in trouble 🙂
buen desafío, saludos
Gracias Eduardo 😀
David, true Litz is not just parallel strands. It is formed like a rope, eg bundles of multiple strands, then each bundle in turn twisted together. The idea is that each strand spends an equal amount of time in the center and in the outside of the rope, which reduces capacitance between adjacent turns. Bottom line: it's difficult to make you own Litz without the special winding machine.
Hi Graeme, yes, I see that now, I was a bit hasty there 🙂
A nice easy one this week Dave.
Grinding certainly made some great looking and sounding units.
Those bench speakers didn't do it any justice but I know they were just for testing purposes
It's nice to get an easy one for a change 1974UTuber. My shop speaker is mono so I had to improvise 😀
@@DavidTipton101 works fine for testing purposes.
You need an old set of those 70s HMV bookshelf size speakers in the wooden boxes with the black grill cloth with gold fleck through them. I always remember them sounding fantastic.
Haven't seen a pair of those in at least 20 years
David, would it be a good idea for you to show people the effect a speaker board has on the sound ? So just a large piece of triplex (or even paper board) with a hole for the speaker, and first show how the sound is without board, and then slowly move the speaker behind the board and stick it on the hole, to 'prevent the acoustic short' trough the air. I miss that sort of examples, only a few people know this effect.
@@erikdenhouter Good idea Erik, thanks.
@@erikdenhouter Even those PC speakers sounded decent when he ran the test in the second video with their plastic cases. I'm trying to remember what they call it when they hang a small speaker on a large piece of board. It's got a name but I can't remember what it is.
Basically you take a good quality 4" driver and mount it in the centre of a piece of high quality ply then hang it from chains at head height. There is a whole mathematical formula for working out the thickness and size of the ply sheet.
And it sounds completely different if you use a Triangle piece of ply to if you use a square. The best shape is an octagon
Dave that's certainly a nice-looking counsel it's too bad it doesn't have FM perhaps you could add Bluetooth as our Caldeira friend does and that way you could feed whatever audio you wanted into the set. For what German raters are going for however you could also probably treated for new car.
Hi Mack, The missing FM isn't a problem as we listen to AM radio anyway but I will consider Bluetooth, it would be easy to incorporate and I have the modules here 😀
I am russian . i use Grundig evry day ., I Like him nice sound ., I feel spirit of history and goodness of Germany ...
Thank you Alexander 😀
David another nice job and Grundig made some really nice Radios ! Far as your signal generator is that a new addition to the shop ?
Hi Richard, thank you. Grundig made some very nice equipment back in the day. The generator is a kit for Silicon Chip magazine, I have had it for a few years 🙂
These old beauties take me back to my childhood. My parents didn’t have one but I hoped that one day we could afford one every time I visited my grandparents and heard this magical sound radiating from this piece of furniture. The quality of sound wasn't a patch on what I have today but back then it was all relative to what we had. A nice project Dave and an awesome job as usual. P.S. Question: What video editing software do you use? I have been learning to edit with “Shotcut” and have transformed my son’s wedding video. I still have much to learn but it’s become my new obsession whilst we are confined to our prison cells in the state of Victoria.
Thanks Graham. It should sound good when I get it going but probably not as good as my LG sound bar but as you say it's all relative. I am using Pinnacle Studio but I am in the process of switching to DaVinci Resolve. I redid our Super 8 wedding video and added sound as well. They came up well, I added a bit of comedy in there of course 🙄🙂
@@DavidTipton101 Thanks Dave. I actually downloaded DaVinci Resolve first up and I believe it's probably rated the best free version. For some reason I couldn't get it to open and the second best option according to many was Shotcut. It's also much easier for beginners so I ran with that. I think now with a better understanding of what's required that I'm ready to try DaVinci developed by our neighbours across the ditch. Looking forward to next week, you really are doing a magnificent job with restorations. Cheers.
@@grahamserle7930 Thanks Graham, DaVinci is a steep learning curve and the free version works well. I will start producing with it in a month or so when I get comfortable with it.
Nice bending tool
Thanks Latürnich, I got it at the electronics shop 🙂
Another great and informative video. I see someone disliked it. To each his own, but really?
Thank Happy Hippo, I always get a few dislikes, must be a RUclips thing 🙂
What a beautiful radio! It's interesting to see something so different.
I was wondering if you thought you could "reinstate" the FM section (even though it was never added)?
Hi Brian, it's pretty unusual in Oz, although I have seen a few since I got mine, that's always the way. It would be much to difficult to refit the FM, certainly more than I could be bothered with. I could fit Bluetooth 🙂
welp i now got something to watch at 2am =D
Haha... thanks 1964corvan 😀
I waited specifically until after dinner so I could legitimately sit down with a bowl of ice cream and enjoy this vid as a part of my evening. As ever, I am *NOT* disappointed. As for twisting the wire - It's not pointless if you learned something, even if that something was that your action was pointless because you already had what you needed.
My brain went there after your beginning description, so just out of dumb curiosity: Could you add FM to that radio? Would it be AT ALL reasonable to do so? Would you need extra tubes and tuning... bits? Is there room on the chassis? Would you need to make an all new dial, or just a retrofit? I think I know most of the answers already. But, you know....
A bowl of ice cream and a video, what more could you want 😀 The chassis is made for FM but not fitted so it would be possible to do but would require a lot of parts. I can fit Bluetooth which has none of the problems you mentioned and I can stream FM or streaming music, that might be an option 🙂
@@DavidTipton101 Nah. No Bluetooth for the Grundig. No one sane would want that for that particular radio. I've been toying with designing and building a new entertainment console with all the mod cons (and some older ones). Bluetooth would work there. But a classic like yours only deserves tubes and string dials and such.
Thanks.
@@stevensansone7502 Haha... maybe 😉
Hey,Dave. Great work. When you said that something was left out thus no FM I was hoping you would be able to get the FM circuit in.
Thank clasicradiolover, we did not have FM when this was imported so no FM is fitted, I was hoping it had been brought over by an individual from Europe and may have FM. If you mean you expected me to fit FM, it did cross my mind but there are no dial markings and it would be a big job, it would be easier to fit Bluetooth 🙂
@@DavidTipton101 I suppose so. I've always been interested in boards and chassis that had the space for an alternative circuit some that seemed as if one or two components added would add a feature to the system. In some Citizen Band radios there are simple modifications to add channels or increase power output.
@@clasicradiolover There are FM boards available that can feed the signal in. I have seen an Aussie radio restoring company videos and they demoed one and it was able to be tuned using the original tuner, I don't know how they did it though. I think it was FM, may have been digital 🤔
@@DavidTipton101 No. I just thought it would have part of it there I'm sorry for being totally out of the park
@@clasicradiolover Yeah, no... nothing in there FM at all, pity 🙂
well done job David.I wonder how is it stereo,if there is no FM
Hi Ivan, thank you. The stereo is for the phono and the tape inputs 🙂
My goodness, ECLL800?! I never knew it ever existed. That's some tube perversion.
same here
There are some of the last tubes they have used in radio's & are rare now, a NIB one will cost you 100 euro !
I was lucky I didn't have to buy one or two Veljko, would have cost more that the radio is worth 🙂
@@DavidTipton101 Would the radio function if you liquidated the output valves and replaced with equivalents or newer generic valves or are they specifically matched to the input circuit / output t/f / speaker stages ? Presumably for Stereo the Phono Input splits through two pre-amp stages or are the ECLL800s doing both the pre-amp and final outputs in one unit ?
@@highpath4776 The ECLL800 is a push-pull output valve and a triode preamp as well. There is also ECC83 dual triode before the two ECLL800 acting as a preamp. So the signal goes through one half the ECC 83 then to the ECLL800 preamp into the push-pull output per channel. I don't know if there is a similar valve that could be engineered to replace the ECLL800.
I love 10cc!
Great Band PauSto Sto 👍

Mapleshade's SILCLEAR Silver Contact Enhancer works wonders in situations such as this; one jar lasts three or four lifetimes...
Hi Tim, looks like SILCLEAR isn't available in Australia. If you mean to use it for cleaning the switch contacts it would be difficult to apply, I can hardly see the contacts so applying it would be hit and miss 🤔🙂
