    @DerekHerbst747 4 роки тому +2

    These old Nordmendes are lovely and sound great. The Germans call those wax/tar capacitors "Teerbomben" (Tar bombs) and you should replace them on sight. I saw a few still in the chassis that I would replace, simply because they will become conductive sooner or later and that puts an extra load on the high voltage windings of the power transformer with ugly consequences. You'll see the difference in the watts drawn after the cap job.

    I think is is good for one to turn their hand to restoring foreign Vintage Radios once in a while ...a change is as good as a rest as they say LOL. One of a number of reasons why I’m turning my hand towards restoring American Vintage Radios. From where you are, it adds an Australian perspective to restoring a German radio. I suppose it’s like me, a Brit, who adds a British perspective to restoring American radios. It all adds to what is the colourful hobby of radio restoration and repair around the world.
    Each year a few Australian Vintage Radios crop up, here in England, at various amateur radio fests, swap meets, and Vintage Radio fairs -doubtless they will have been postponed, or cancelled due to Corvid-19. Normally, after buying British radios I then go on the lookout for American, and Canadian types, so, from now on, Australian, and New Zealand radios will be on my ‘look out for’ list ...they certainly look interesting. Having said that, I have recently acquired a French radio, Radialva (model: Super But) that will hopefully feature in a video sometime later this year.
    There is a fellow who appears to specialise in restoring German radios called M Caldeira, his channel is ‘Electronics Old and New’. Go check him out if you are not familiar, I’m sure you will be impressed.
    Best regards Dave, from Phil.

    • @DavidTipton101
      @DavidTipton101  4 роки тому

      HI again Phil. I do know Mr Caldeira and have been watching his videos for years, his explanations have been very helpful. I agree with you, a little radio diversity is good. Any Aussie radios in the UK would have been brought over by expats I would think, I can't see us exporting to the UK. All our club activities have been suspended until this virus is over. Thanks Phil and all the best 🙂

    Well done. The ERO (ROEDENSTEIN) capacitors are the troublemakers. All capacitors that are filled with yellowish wachs, Black terr, and white plaster typisch material are paper capacitors wich leak horrible. On the opposite you have in these 50-60s German sets a lots of very stable ceramic capacitors and high quality parts, wich makes the really dependable with a very nice sound.
    The stuck changing mechanism for AM FM can be lubricated with brake cleaner, at least that had worked on my sets. But you have to make sure that it completely dried before you put power back on, if not you risk to set the set own fire as break cleaner burns well.
    Note that the 6E5C has a smaller negative grid voltage then the EM34 so the show might behaving different.
    but the 6E5C still seem very dark, too dark for a new tube. The soviet tubes usually don^t last as long as a proper Telefunken, Siemens, or Valvo tube.

    I've got a Grundig Majestic 3165 , a five band radio , that I picked up in Nurnberg , when I worked at Grundig. The radio cost me $ 100 in the Grundig family store , at the factory. It's still in original condition. I have never recapped it or repaired it other than a few tubes and pilot lamps. In the meantime I did fuse the line cord and the B+ lines. The receiver works perfectly on long wire AM and outside FM dipole. I did check the alignment and it was spot on. I have tested the filter caps and they look good. The piano key switches did need cleaning and lubricating. I'm hesitant to do anything to it. The radio keeps me company in my radio shop. I can play phono or tape through the rear 5 pin Din jack. The Audio is only monaural, but there is a three speaker sound system inside the cabinet with an external T jack on the back panel. When I bought this audio was only Hi-Fi. Stereo came along later in the mid 1960's. I bought it in 1964 , however I think it was NOS then. That's why I got a good price on it. Looks like yours is coming along nicely. Perhaps I'll be inspired by your success to recap the chassis.

    • @DavidTipton101
      @DavidTipton101  4 роки тому

      $100 for a radio was pretty expensive in 1964 I would have thought Cosimo but there is so much work in these European sets. That works out to about $1.80 a year so far so still good value. I hope all is well with you virus wise 🙂

    I enjoyed the restoration of the Normende radio. This week for me was a crossover point for more modern vintage radio receivers. Finding exact fit parts for a thirty year old solid state receiver is a challenge too. A scope is a necessary tool for solid state as there is no device pulling to test. Transistors can simply test in circuit with two to three voltage readings. Working on a solid state receiver offers several challenges from radio, phono to tape devices, its more like a system of sets. I'll still dabble in tube circuits, but have discovered a new affinity for transistor circuitry.

    It would seem that radio might have made its way from the UK to AU. Radiospares in the UK was a huge supplier to the radio and TV trade back in the day, and I still use them for components myself.
    Those RS smoothing cans are actually not too bad! I have some NOS ones and they have responded well to reforming. I’d say that can was made in the very late 1950’s, so the original Elko or Siemens smoothing can must have had a short life!
    I mainly collect these German sets, and the Nordmende FM tuners in them are a real pain to work on sometimes. I recently did the later 1958 version of the Elektra, that had an open oscillator trimmer capacitor in the FM front end. That was a pain to replace!!
    Those ERO capacitors (toffee caps as we call them) are just awful! They don’t even taste like toffee either!

    One tip: I saw you working on the large capacitor on the lathe. To prevent the machine to be filled with dirty stuff, place a large sheet of paper over it, underneath the capacitor. It's easy to remove afterwards and your machine will nog get all the chemicals from the capacitor which might cause rust.

    Hello Mr. Dave, finally I decided no work more in the Nordmende Elektra d12 radio repair, after a lot of man hours, money and patience I can't got the radio repair. I must tell you this is the first time this happen to me, I have repair a lot of tube radios from my own collection such as a Transoceanic Zenith G500, several tube radios GE 1949-1960, PHILCO tube radios 1960, ZENITH TUBE RADIO J508B, PACKARD BELL 5R1, MOTOROLA 55C1, RCA 6X5A, and more. I have an oppinion about the electronics design of german tube radios they work with a power supply of 220 vca and a rectifier to 220 vcd, this is dangerous in many ways, it is very difficult to find shortted circuits, the schematics from the manufacturer have conffused information. Thanks for all your support help, best regards.

    • @DavidTipton101
      @DavidTipton101  Рік тому

      That's unfortunate Rodolfo, I wouldn't worry so much about the high voltage, 120 will kill you as well as 220. Be very careful and don't touch anything when the set is powered. You need to break the set into pieces to determine where the fault is. Does it work on any of the bands, AM, LW and FM. Does the phono input produce a sound when you touch it, is there any hum from the speaker... things like that. Take a break and have another go next week. Good luck 🙂

    Great job so far - these old German sets are some of my favorites and really they are hard to beat when going well. I am fairly sure yours was intended for the German market. Funnily enough, the first one I had (Grundig), someone had nicked the speaker out of it too. On older German home market sets, the FM band only goes up to 100 MHz.

    Whilst I do like the NordMende radio sets, especially the transistor portables et most of the earlier 'German' valve sets have some (Grundig was NO exception later on either.) real issues for wear and tear that can be seriously problematic to fix. 👀 The push button selector system is one example. The slider pins and contacts can wear to a point you have to strip out the entire unit and laboriously attempt to salvage it et 👀Getting at some parts, means stripping out and down (my partners fav occupation) 😁 Not forgetting of course, as per the Siemens radio gram that I am currently working on (1948) that has that SELENIUM rectifier, which I seldom have found other radios of the same era. where they have not failed. 👀 The FM or VHF system can be testing on the patience (if not the soul ). Seem to slip out of alignment AND the two valve system, EF41s re VHF have posed problems. We have to remember that the Germans et were very much in the early days of UHF / VHF (A lot of their communication field devices worked on UHF)👀 The power transformer was also destroyed probably by that selenium rectifier failing. 😒They also liked using the radio system et built in given sections. 👀Alright if you bear that in mind when working on them. Most of the circuit diagrams (my Siemens in particular) has set colour coding abbrev letters, values AND voltages (20,000 ohms per volt). I had the original power transformer rewound. Used new bridge rectifier / ballast resistor AND 4 main power electrolytics et Overall on the Siemens the voltages run to over 300v. 👀It also has five speakers. 2 mid, 1 low and two voltage powered tweeters. 2 LS output transformers. 3x15ohm, plus the tweeters. Cross over networks. The entire audio output stage is quite complex. 👀 9 valves. Power via the transformer gives 2 x 6.3 volt (2Amp) 240v (UK) primary with 300v x 2 secondaries (750mA). A second power transformer for the turntable unit et 55v x 2.👀 Internals now working and alignment OK. Switching trouble free. (finally 😒). Overall whilst I have THREE sets in my collection that are German sets I'm NOT crazy enough to desire adding any more thankyou! 😁NEWBIES! Many of the so called SYLVANIA valves are RUSSIAN made and even listed as direct equivalents they quite often are NOT! The QUALITY of the valves also is questionable. If you can source brand name western valves ? Do so. Ex military types can also be OK for replacements. I HAVE on occasion swapped out the valve bases and changed valve types/equivalents et The UKs Valve museum website and or the Radio museum website are superb for valve information, radio / electrical devices et NOT forgetting Ray's 'Radio workshop' (UK) website for a lot of really good info on radio and more. 👀 Thanks for the vid David. 👍 It is always good for others to appreciate someone's hard work, patience and achievements.

    I've restored many German sets in the past. You did well to restore the PSU cap (I wish I had a lathe)
    I usually either reform that cap or replace with a modern 50+50uF. I'm not a big fan of those small electrolytics you have fitted, as I've had bad experiences with them.
    Any ERO cap should be replaced on sight. Some of the silver coloured caps are not that bad and hold out quite well.
    Selenium rectifiers have got to go and replaced with a silicon bridge + ballast.
    EM34 tubes are ridiculously expensive so I use a Russian 6E5C tube re wired accordingly.

    Excellent video Mr Tipton, thanks for uploading!! I am currently restoring EXACTLY the same Nordmende Elektra and have filmed it to upload on YT in a week or so. This is such an amazing coincidence! Imagine 2 people restoring a 1958 radio, same make and type in the same month of 2020. I was gobsmacked when I saw your video just now :-)
    Just some quick info if i may: @ 15:40 you fell for the same thing as i did initially, that cap is not shielded, its a 0,01 cap plus 10 meg resistor combo, visible on the schematic as R57 and C97 in that square dotted outline, I just soldered a resistor between pin 8 of the EABC80 and chassis, its the grid pullup for the triode section. I didnt see you replace the electrolytic C87 , you point at it @15:27. This one is FM ratio cap, veery important to replace, even if the old one tests good it is not.
    The ECC85 often goes duff and also the ECH81. Although the ECH may work fine as the converter on AM, it may perform weak on FM where it doubles up as the 1st IF amp. I always swap those 2 valves against known good ones from another radio before attempting to alter the tuning of any coils, especially those in the FM tuner, the factory settings are almost always the best.
    For the magic eye I went a totally different route using a cheap 6AL7GT with a small tweak, will dedicate a separate video for that.
    The labeled terminal strip on the rear of the chassis is a row of test terminals Nordmende used to access all relevant test points in the schematic without removing the chassis, quite a useful aid when repairing...
    Cheers from Germany, Ralph

    • @DavidTipton101
      @DavidTipton101  4 роки тому

      Hi Ralph, that is quite a coincidence. The cap and resistor was shielded, I just missed that it had a resistor in it as well as the capacitor. I didn't replace that C87 cap, it was the only one I didn't do, as you say, it tested perfectly. I will change it when I fit the new grill cloth, thanks.
      I didn't have any spare tubes to swap in for comparison, I was lucky to have the two missing tubes. The AM and FM coils had been fiddled with at a previous time so I needed to align them.
      I looked at the 6AL7GT but the exchange rate and postage makes them too expensive here. I assume it works OK.
      Good luck with your project 👍

    Nice radio, love the Nord Mendes, but you managed to a waste a perfectly good crossword puzzle, mate. These days they're practically legal tender ;). I enjoyed the magic eye swap-out. I plan to do the same with a 1950s Japanese radio that didn't come with one, but I found a nearly identical schematic that does show one. So, my radio will get an upgrade.

    Interesting project. I never found magic eyes of any practical use for tuning in a receiver, where my ears are better, but they are useful for recording levels on tape recorders and also on capacitor testers. BTW: The German word Mende is pronounced like 'mender' (with a soft r).

    German paper capacitors sometimes look different, those white ones are surely fine? I bought a small HV insulation tester from China a few years ago that can test up to 1000V and it runs off one 9V battery. If I am not sure about the capacitor (perhaps it is a type that I never saw before), it will tell you instantly if it is good or bad (or if it is about to fail).
    For the FM, test all the valves first (especially the ECC85 and EABC80, if the set has one). There could also be a dried up 5uF stabilising capacitor in the ratio detector circuit that sometimes causes distortion. And check if the IF cores are still untouched, as there might have been someone in before with the screwdriver there. FM alignment is a bit tricky, the best way is to use a sweep generator (wobbulator) and a scope.

      Hi michvod, I have replaced the wax caps and the white ones now as well, I thought the white ones tested ok but I tested them again and they were suspect so out they went. I have a Chinese tester, might be the same as yours. I will check the caps in the ratio detector section but I think I got them all, thanks for the heads up. The IFcans have definitely been 'touched', I will sort that in the next video. I don't have a sweep generator so I will do it as the service sheets suggest. It is my first FM alignment, wish me luck 👍😀

    Nice to see a Magic Eye again ! Looking forward to part 2.
    I've been working through your vids this week here in shutdown UK - you certainly are good at fixing the appearance of these radios, as well as the electronics. I grew up with valves in the late 60s/70s, and although the electronics hold no fears for me, case repairs do :o) When you print onto wet transfer sheets, is your printer an inkjet or a laser ?
    I enjoyed watching you making new acrylic windows for dials in two vids by different methods.
    Now you've prompted me to go and look for a small isolation transformer like your Aussie one - I've never owned one and I think I should. I do have a dim bulb tester though, built to test a friend's Pye 15A. It does't look as good as your latest dim bulb tester version though - what a great front panel !
    Is the Pye 19A (I think) on your shelving due for a repair, or is that already done ?
    I had never seen an Aussie AM bc band dial before - with the states and two-letter idents all marked - new knowledge for me.
    Request - when you repair a radio with SW, could you whizz the dial through that band just for those of us that like to hear that, as well as the AM bc band ? Ta !

    • @DavidTipton101
      @DavidTipton101  4 роки тому

      Hi Dave, thank you. I use a laser printer, the transfer sheets are different for both types of printer. The isolation transformer is a good safety device for all repairs but essential for hot chassis sets. The Pye set has been done, it is an Australian model APM I think. It was in bad shape and I had to re-veneer it, I did it before UA-cam. It had an intermittent fault where it would work all day and the next day there was no sound, turn it off and on and it was ok again, it was a head scratcher. It turned out to be a bad connection in an IF transformer. Aussie dials pretty much all had that layout. I can't get much in the way of SW reception due to my location and limitations for a decent antenna. I can get some of the islands north of us and sometimes NZ stations. There is at least one SW Aussie station but they operate at a higher frequency than most radios I have. I only have two radios with that frequency range and one is the Pye set. I might dust it off one day 🙂 ATB

      @DavidTipton101  8 місяців тому

      Hi muxxor. I don't have anything specific on that but it sounds like the lock plate on the switch pack is slow to move to the latch position. The latch plate is a thin strip of metal that transverses the width of the switch pack. When you press a key the lightly sprung plate slips behind a slot on each key mechanism. Yours may have a broken or weak spring or the latch plate is gummed up making it slow to react when you press a key. When the 'Off" key is pressed it pushes the latch plate away to unlatch any latched keys. Check and clean the the latch plate and make sure it moves freely and the spring is still doing it's job. There may be another cause of course but that seems to be what you are experiencing Good Luck 🙂

    Hello Mr. Dave, I will appreciate your valious help, I got a Nordmende Elektra d12 German radio, after a full restore including a new diode full wave rectifier, the outlet voltage from the rectifier is 375 VCD and the transformer voltage in to the rectifier is 257 VCA; the radio schematics show a voltage maximum of 257/262 VCD, my question is how make a voltage drop from 375 VCD to 257 VCD?? It also the two light bulb terminals are shorted when one of the termimals is grounded, this is detected with a bulb dim protecction. I know ohms law, but please give your opinnion; thanks a lot.

    • @DavidTipton101
      @DavidTipton101  Рік тому +1

      Hi Rodolfo, is the radio working? Do you have the magic eye fitted and working? If so, there is something wrong either with your measurements or maybe the primary transformer tapping is set to the wrong voltage. Test the filament voltage is 6.3volts AC. The voltage rise from replacing the rectifier should be in the order of 20 to 30 Volts. 120 Volts is way too much. German radios operate on 220 Volts usually if not an export model, your local voltage may be higher than that 🙂

  • @hestheMaster
    @hestheMaster 4 роки тому

    Excellent job so far. Think the Russian magic eye 6E5C isn't getting enough voltage. Maybe the resistor drifted or your not getting 220V.
    There are some switch contacts that may need cleaning. May need to replace capacitor C80 in circuit too. Seen a video of one in action on UA-cam.
    It should be very bright!

    • @DavidTipton101
      @DavidTipton101  4 роки тому +1

      Hi HTM, thank you. Yes, I agree the eye is underpowered I think it requires 250V but the supply is 210V or 225V depending on the wave selection, the supply voltages are correct per the schematic. The eye is dimmer than it should be but quite bright enough when in the cabinet. I replaced all the white caps including C80 and the replacement is mentioned in part 2. The few I measured originally came up spot on so I left the rest but a check later on revealed they were all out of tolerance so out they went 🙂

      The anode voltage is a little low (230V not 250V) but boosting it made no difference, the cathode is at ground potential. When the eye is fitted in the radio it looks ok, not great but ok.

    Not a good idea to have the capacitor residue dripping on the lathe ways.
