  • Steve asked me to help get his project radio working. It's an STC Console from 1938. I got the radio to work but the field coil in the speaker has shorted. I haven't rewound one before, "it can't be too hard" I told Steve.... "leave it with me". Can I do it?

    Hi Dave. I found myself holding my breath watching this. Winding 1.8km of fine wire and solving the breaking issue. Well done. I reckon refitting loudspeaker cones must be one of the most fiddle parts of radio repair. These speakers would have been expensive to make.

    Dave your skills never cease to amaze me. The description of how electrodynamic speakers work was very clear and understandable. I have restored a slightly newer STC model (536) which has the same setup but fortunately the electrodynamic coil was intact (but not the speaker transformer). A pleasure to watch your work as always.

    I got given a Rola version of this speaker at primary school Y6 of '83 by one of the kids, I took it home to plug into my 1w Audiosonic tape radio, I barely got sound with radio fullblast, I thought the voice coil was 2000 ohms, since that was stated on the speaker, What a feeling by Irene Cara was playing. the speaker had the tin cup cover and screen voice coil cover. I brought it back toschool telling the kids the speaker is too big for the taperecorder, they had a great time unravelling the field coil while wrecking the speaker

      My cousin Jim had a late 50's Hotpoint by AWA radio gram in his bedroom when he lived at his mum's back in the 80's, he told me about the gram at Joanne's wedding late 84, I asked many questions about it, he said the speaker is 4 ohms 4w. I imagined it might have a field coil Rola. I also imagined it would sound good with Durran Durran Wild Boys played full blast. When Jim's last CRT TV went, he had no room for the gram, a widescreen TV was coming in, he said I can have it and 2 dead CRT TV in 2010. I took the CDs and papers out of the record compartment when I collected it from verrandah while he not home, he rung up and said I told you to take everything out of it, demanding the records back, he wanted Rock around the Clock 78 and 2 Les Paul 78's back and Tom Jones Green Grass of Home album ( that song was used on his photo slides after his passing 2 yrs ago). A 6BV7 valve and MSP 12PW 6.5 ohm and 5" 3 ohm in Hotpoint radio gram. For some reason the record player sound extremely tinny, BSR with ACOs cartridge@@DavidTipton101

    As for the new wire you got, it's probably a more brittle alloy, or they didn't anneal it enough so it was brittle. Success in the end though! Fantastic.

    Great job (as usual) repairing this electromagnetic speaker.
    Another reason why the field coil is less thick could be because your winding machine winds the coil so neatly, which is not strictly necessary for a field coil. The original one was probably wound much more unevenly.

    Wow, nice job! I'm sure the owner will be happy. I've never seen a field coil rewound before and I'm sure you couldn't have done that with your old winding machine, even after you modified it! A bit strange, your wire having a different resistance per meter to the old stuff. Looks like matching the DC resistance was the right way to go. Trying to match the number of turns would probably end badly, especially with the length of wire required per turn increasing with the effective diameter.
    What a coincidence that we both released videos about 1930's STC radios at exactly the same time!

    • @DavidTipton101
      @DavidTipton101  Před 7 měsíci +1

      Hi Don. Thanks. I'm just watching your video now. I couldn't work out the resistance difference either. You would think it would be the same. I was originally going to match the turns but I couldn't get the old coil off in one piece and then I realised the resistance would be way out. The metre measuring wheel worked well to, a last minute purchase for China. I could believe it when your video popped up, people will think we are in cahoots 😄

    First off, I'd never have that kind of patience. It's amazing that you rewound that many turns of fine wire.
    As for matching the number of turns vs. resistance: Perhaps you could use thicker wire and match the number of turns. The resistance would come out low and if was more than, say, 10% low add a series resistor.

    I had to rewire a 1963 Sears electric guitar Hershey bar pickup. Nobody could rewind it for me since there were no holes in the bar. So, I used my Shopsmith and mounted the bar to a piece of wood that I turned smooth. I mounted have of a magnetic door switch to the back of the wood and fixed the other half so it would close by the magnetic. I wired the switch to the circuit board of an old desktop calculator at the + button. Those old calculators would work as 1+++++++++++=13. With the 42 awg wire, it was hard to do, because of instant start breaking the wire. Don’t remember how many thousand wraps it needed.

      I had to look up Hershey bar pickup and Shopsmith 😄 There is a lot of fine wire in there. That's thinking outside the box using the calculator, well done 👍👏🙂

    I had to recone several speakers over the decades. I never had to rewind a field coil though. The hardest part is getting the voice coil centered. I was able to order kits that came with the alignment shims and special glue for the cone to frame. Great job!

    • @DavidTipton101
      @DavidTipton101  Před 7 měsíci

      Getting the voice coil centred can be tricky, there is not a lot of tolerance there. We don't have access to recone kits as such here, at least not at a reasonable price. We can get speaker components from China but they seldom fit these old speakers. Thanks FK 🙂

    A decade or more ago my next door neighbour here in Kenmore lent me his Dremel which of course immediately burnt-out. I offered to buy another. He declined, and of course being an old-school pre-Telstra man, he rewound the motor. Why did I not know that he is capable of such things!? ps He has just celebrated his 97th, ppsThumbs up!

    Hi Dave. The difference in measured coil resistance on the original coil from the specified resistance can easily be accounted for by temperature. I believe the resistance was specified at 20 deg, and only about 5 degrees above that can add 50 ohms. It's worth considering that, when measuring copper wire. ☺

Yes, inductance would have been good but with no real reference I couldn't use it. I have a lot to think about for next time 🙂
