A Loewe Opta Meteor 1781W that has been dropped. I was asked by a friend if I could repair it. The case is broken after being dropped but he said it worked. When I try it I am disappointed to find not everything is working as it should. This is going to be a bigger job than I thought!

I like how nothing intimidates you David. Most people would never try to rebuild a transformer like that. You’ve taken Antique radio repair to the next level.

@antoniobarra2752 Год назад

Intimidazioni? Ma lei scherza,questi tipi di interventi sulle radio o sulle tv d'epoca vengono fatte con materiali d'epoca o sostituzioni che non intaccano l'estetica dell'oggetto.E ribadisco che come artigiani siamo i primi nel mondo, i trasformatori li realizziamo meglio di quello visionato nel filmato.Le auguro buona giornata.

Woohoo, another Dave Tipton video. I've been binge-watching your old videos lately to get my Dave fix. Luckily my memory is pretty shot these days so what was old is new again. Old age is great, you're always meeting new people and you get to hide your own Easter eggs. I told my son the other day to quit making fun of my memory otherwise he'll be sorry when there are no eggs under the tree this Christmas. Anyway, a superb job as always and I hope your eyesight remains good as well as your health in general.

Dave, I really enjoyed this one - it's great to see that new winder in operation... and I immediately went shopping on AliExpress afterwards to see what I could get one for... they're actually not too bad, although I would still be shot if I bought one at the moment 😂. And I'll echo others who say your videos are never too long... the only problem with them is they make me feel guilty for not getting one of my own out in far too long... although I have a three week deadline to get a couple of things done, so I will have to get back into the garage asap. Great work on this one though - and thanks for sharing it with us. Cheers, Steve

@DavidTipton101 Год назад

This was a great radio adventure, you outdid your self Dave, and what a great wife to let you spend your vacation money on a coil winery machine. Sorry to hear about your vision issues but sounds like you're going to be okay. Suggestion, use a magnet near were your drilling as well as your paper to prevent shavings from getting to the components.

@catey62 Год назад

A little tip that I dont know if you've heard of. but if you want an environmentally friendly way to remove rust, mix molasses with water in a 9-1 ratio. let the parts soak in it for about a week if you have the time, then just give them a good scrub and they'll come up nice and clean, especially if they only have minor rust.

@DavidTipton101 Год назад

I think I have heard of that before but forgotten about it. I usually don't have that much time but I will give it go if I can. Thanks @catey62 👍🙂

@bofor3948 Год назад

I haven't wound a transformer since my apprentice days back in the 70's. The machines we had were a lot slower than that chinese model. Really impressed that you have the patience and tenacity repairing these old vacuum models to rewind transformers and coils. I try to adapt similar transformers from basket cases before I shelve it (for Ron) or calling the radio i am working on a basket case. Nice work and looking forward to the next part of this restore.

@DavidTipton101 Год назад

That looks like my radio made by kapcsh in Austria. Same set up with push buttons and shows places like Luxemberg on the face and also has the magic eye tube it was made in 1957 and I bought it at a garage sale 2 yrs ago for $20. It needed a new ferrite core and some wires resoldered. Mine does work. You sure went the extra mile on this one David. Rewinding the entire transformer yikes. Love watching you work.

Another excellent repair, 150v mains tapping on the original transformer makes me wonder where in the world had 150v mains?

@DavidTipton101 Год назад

I was wondering the same thing Christopher 🤔🙂

@BobAndersson Год назад

Thank goodness the mains transformer on mine worked as that would have been a total show-stopper for me. I chose to restuff the rectifier (and dual electrolytic) so I needed a dropping resistor as well and also a mains dropping resistor to get the filament voltage right as it's 240V plus here. I had to totally strip and refinish my cabinet which was terribly faded but at least the veneer was in good condition. I also dyed the grill cloth in place (it was too well glued down to remove) using a Procion MX gold dye. Very scary to do but it came out well - if you're tempted then test first as it's very easy to overdo the colour. If you haven't spotted it already then there's a bandpass function built into the volume pot (push/pull) which you'll need account for during AM alignment. But it's great to see you've finally been able to tackle this radio and to hear that your health issues are behind you. I'm looking forward to Part 2. Thanks for sharing.

@DavidTipton101 Год назад

Hi Bob, a failed transformer is a show stopper for most repairers. It's good I now have a repair option available. Thanks for the grill cloth dying tip, interesting. Well... I know now there is a bandspread function, it caused me some grief in part 2. I will just say I wasn't aware it was there... 🙄

@sw6188 Год назад

Reading all the comments about starting your own transformer winding business, most of them are joking of course but the reality is that there are very few transformer winders around now who will deal with small units like these. Most of the companies that do transformers are more on the industrial side and charge quite a bit to do small transformers. Over this side of the ditch in NZ I know of only one chap who is still winding transformers and he's getting on a bit. Eventually he will pass on and there will be one less option for getting them done. I have encouraged a young chap who is surprisingly skilled in electronic repair (he's only 17) to look at learning the art of transformer winding as it will serve him well for the rest of his life and provide a little extra income on the side.

@DavidTipton101 Год назад

I don't want to be winding transformers all the time but very handy if I need to do one for myself or the occasional friend. If I had tried to get this rewound it would have cost hundreds of dollars and the guy that used to do them for me retired. I might as well put the money into a new winder. I hope your young friend can set himself up but I doubt there is much money to be made from the venture, at least from the hobby side of it 👍🙂

@donhall2759 Год назад

Great video! You wouldn't think something as electrically simple as a transformer could be such a complex nightmare, but here we are. Excellent tip on the hole saw, but I couldn't get that to work for me. But, the cheap tools emporium had some chassis punches that came to my rescue so that's an alternative. Looking forward to your next video as always.

@DavidTipton101 Год назад

Hi Stephen. They are a simple device but a bit of a learning curve to get a decent result. I have been looking for chassis punches, especially 'D' punches but they are many hundreds of dollars, even for one punch. A much neater and cleaner chassis hole making option. Thanks Stephen 👍🙂

Stay well David. It's always nice to see that the exceptional build quality of those 50's era German radios is still appreciated all over the globe. The transformer is faulty because of a wrong setting in the voltage selector, I guess (240V vs. 220V spec.). We can make do with the original transformer here in Europe without problems, even after all those years. Don't hesitate to ask European enthusiasts for more antiquities, we can still pull those old radios from the junkyard on a regular basis, if you can pay for shipment :)

Fantastic machine and what a wonderful understanding wife you have there, sacrificing the holiday money for the winder. Watching the machine spinning and the discrepancies in the winding, I wonder if it's just winding too fast and there's a bit of bounce in the wire especially since you're winding onto a square spool. I dunno, just a thought. Great to hear you're getting through your health issues, that's the most important thing of all.

Respect, good recovery from egg-on-face (desk, schematic). There looked to be a lot of vibration when winding (some to be expected, but the table looked to be joining in the fun). You can use a step drill instead of a hole saw, if you use it in a drill press you should end up not having to file, he says, confidently.

@SeekingTheLoveThatGodMeans7648 Год назад

The bouncy table might well be why gaps were developing in the windings. Something to add mass to the whole setup (like stone? cementing flagstones to the top of the table?) could get that issue sorted.

@DavidTipton101 Год назад

The table is quite solid, the camera was shaking a bit. The problem with drilling the hole was that it was off centre to the original hole. I used the piece of wood to create a new off centre pilot hole 🙂

The winding machine is just great and for somebody like you it's money well spent. I've seen a few other videos of guys working on similar German radios who were just as surprised to discover s selenium rectifier in a ''capacitor can'' format. One of them almost never figured it out in fact :-). Can't wait for part 2 to come out, i'm especially curious to see what you are going to do with the damaged corner.

@michvod Год назад

Few notes: leaky paper capacitors always read high on DMM or similar cap tester. Tester is measuring the time to charge the cap, and the time is now longer due to leakage. You should get a leakage tester (insulation tester) to be sure, good cap will read OL on such tester (more than 1000 gigaohms). I replace them on sight, except for really special cases (like a tone cap with shield that has 0V DC on both sides). Small value electrolytic caps: I usually put leave them in place, but disconnect the + side (the one that isn't grounded) and keep it for the looks. I install a new small capacitor underneath, so that some of the originality is preserved, and the capacitor body acts a bit as a grounding shield. Also the tolerance for those old ones were -20%/+50% or even +100% at some cases. But the main problem is leakage current. Those caps are usually in high impedance circuits and even 0.1-0.2 mA leakage current can be too much. So I do 3 tests on caps: 1. capacitance, 2. ESR, 3. leakage current at close to rated voltage. Just my 2 cents. Btw really liked your transformer winding :) I'm sure this radio will end up even better than it was from the factory

@DavidTipton101 Год назад

Thanks for the notes @michvod. I was aware of most of them. I have a megger and do use it to test caps, I don't usually bother as I replace them anyway. Interesting idea to hid smaller new cap under the old ones. The winding was interesting. I hope to get better as I do more 👍🙂

@michvod Год назад

@@DavidTipton101 Yeah, I love that winding machine, and your skills. Yeah burned transformers aren't fun. For the caps, I try to preserve as much of the originality, so leaving the old components in, of course disconnected is always a consideration. I also restuff paper capacitors sometimes, but only on rare radios.

@Donno308 Год назад

Hi David What a pleasure to have a nice long video from you. Very interesting! With that new winding machine it seems there will be nothing you can’t fix. I’m sure it was money well spent, especially as it seems your interests are going in that direction. Sorry to hear you’ve been having vision problems. That would be incredibly frustrating. Seems you’ve had one thing after another lately. Hopefully it’ll be plain sailing from here on. All the best.

@DavidTipton101 Год назад

Hi Don. Thank you. If you need a winding job done, I'm happy to help. My vision problem started quite suddenly and escalated quickly over a few months and a few months recovery. I had a fine surgeon and he fixed it up brilliantly. I'm back to nearly as good as before sight wise. Health issues seem to escalate with age... funny that 👍🙂

@martinoakley6651 Год назад

Another excellent video David and a new toy in the bargain. The Tipton Mk1, 2 and 3 coil winders were really good models - I think you should pick that one up again!! Anyway, really enjoyed seeing the start of the Loewe - hopefully you will be doing the cabinet resto as well!

@DavidTipton101 Год назад

Thanks Martin. I would have loved to have kept going on the mark 3 version but I was spending so much time on it I wasn't getting anything else done. The cabinet will be done 🙂

Great to hear that your okay! Very interesting your new transformer winder, great job. Also noted the 'Vegemite' product placement. Always enjoy watching your channel. Cheers for now!

@DavidTipton101 Год назад

Thanks Peter. The Vegemite jar is my alignment tools holder 🙂 The winder will be great for future projects 👍

@edwardhannigan6324 Год назад

Wow, what an episode..That transformer winding etc...Being a newbie I'm trying to follow the process and it's a work of art mate..! Still trying to get my head around it, but fab repair and technical info..Top job..Ed..uk.. 😃 ( happy to hear your vision is improving )

@DavidTipton101 Год назад

Hi Ed, thanks. Transformers are pretty basic, a bit of math and they will work. Trying to get a neat end product is a little tricky. Thanks Ed, my vision is pretty good again 👃🙂

@domtrimboli6238 Год назад

Very nice job on the transformer 👍 Most people would install a replacement. I like Loewe radios, worked on some lions (= Loewe 😉 ).

@DavidTipton101 Год назад

Thanks @rotwang83. A replacement wouldn't be as much fun 😀

@tomsing6384 Год назад

Holy Cow, and you said that you were not comfortable working on solid state devices, but you rewind transformers, Mr. Carson's Lab can't even do what you do with transformers, you are amazing, if you were 25 you could probably start a rewinding business that would make a million dollars (AUD) thanks for showing the world how at lest to do transformers.

@DavidTipton101 Год назад

Thanks Tom. I might have to start a transformer winding business to pay for the winder 😄😉

@wayneparris3439 Год назад

Dave, I just started watching this video, I'm looking forward to another outstanding adventure. Now that I am on the east coast of the US. I so seldom get to see a just released video from you. It is 3 46 am and I just woke up for no reason. I do watch and like all your videos though commenting on them is not as frequent. This looks to be a nice adventure so, back to the video. Rewinding a transformer is an adventure. Nice winding machine!

@DavidTipton101 Год назад

Hi Wayne. I hope you enjoy it

@wayneparris3439 Год назад

@DavidTipton101 very clean rewind. In 73 I studied rewinding motors, I wish we had equipment like that! Modern csps are so much smaller than back then, much better quality too. I would be happy to buy caps from Carl but shipping half-way around the world is not practical. It is a great detail that the transformer label was in such great and reusable condition. Still saying the occasional prayer for your past health issue. ❤

@DerekHerbst747 Год назад

Lovely stuff, Dave!! I could use that winder. You've gotten me thinking thinks I shouldn't think!!

@DavidTipton101 Год назад

Amazing job. Really cool to see you tackling a German set again. Here I am struggling to make up my mind about what to do with a bad field coil and you just rebuilt an entire transformer. Impressive. Looking forward to the next video.

@DavidTipton101 Год назад

Rewind the field coil. Mechanical hand widers are cheap and will do the job. Thanks @retro_tech 👍🙂

@tubeDude48 Год назад

It will be interesting what you will do with those buttons! WOW! That is one slick coil winder!! That transformer looks like it's been under water! --- At 36:30 I use a small butane torch to the wire; then some fine sand paper to remove the varnish.

@SeekingTheLoveThatGodMeans7648 Год назад

I'd always simply used fine sandpaper or emery boards; no need to burn the insulation which might also embrittle the copper wire.

@DavidTipton101 Год назад

The winder is very good , I have a number of projects to use it on. I have used a torch in the past, that works ok if the wire doesn't get too hot 🙂

@gregf9160 Год назад

@DavidTipton101 Год назад

@JerryEricsson Год назад

Great video, you were doing fantastic rewinds with the old system however the new one looks so much easier to use. I have watched a lot of videos on repairing the German made sets and it seems the transformer is usually a major set-back in these repairs. Doing a full rewind surely is the answer for those with the skill, work arounds abound and are interesting to watch but the skill that you have in these repairs is mesmerizing, Great to watch such video's early in the morning with my coffee and Danish!
