    I took the cable apart so if anyone else with these headphones has this problem again here's the pinout:
  3. stormman34
    so do you have any more ideas or should I just start to check every little piece?
  4. stormman34
    I don't have neither of those things and I don't think I can buy the ptc
  5. stormman34
    it does indeed still blow, also, I'm running short on fuses
  6. stormman34
    C-D is 18V and both E-F and F-G are 23V so about right, this means the transformer is working correctly and I should look elsewhere, right?
  7. stormman34
    remind me, you measure voltage by putting one multimeter-thingy on A/B and the second on C/D/E/ F/G?
  8. stormman34
    so you guys are saying that the transformer isn't faulty, right?
  9. stormman34
    sorry, didn't see it under the photo, it's a 160mA 250V
  10. stormman34
    didn't work
  11. stormman34
    that probably wont work since the circuit looks like this: and if I turn on the switch it blows the fuse however I didn't know about this and for the entire time I was working on this I had removed a steel plate (around half a kilo) that was sitting on top of the motor (since it would fall down when I turned the player around while working in it). I'll try it again with the steel plate on and update you on how it went.

    yeah, I fixed that, I was just checking the giant capacitor (if it has 0 resistance) and forgot to solder it back for the photo
  13. stormman34
    no, I can see it, it's intact
  14. stormman34
    also, I looked a bit more closely and found this: it seems like pins 1,2,3 are the ones I called 3,4,5 and seeing as their current and voltage are the same it probably makes sense that they have low resistance to each other, right?
  15. stormman34
    approximately 79Ω

    I found a super old record player in our basement and I'm trying to fix it. Everytime I turn on the switch it spins a few millimeters and then stops, when I check the fuse it's blown. I've replaced some leaky caps but it still doesn't work, before I delve any deeper into the electronics I wanted to check if the transformer isn't faulty. The transformer is a 9WN 667 07. I live in Europe if that matters. Power goes (through a fuse and a switch) straight to the top. The resistance between the pins are as follows (I did scratch the surface of the solders so the resistance should be measured properly): 1 - 2 - 33Ω 1 - 3,4,5 - 100-200Ω flashes but then it shows infinite (making the tolerance higher on my multimeter didn't show anything at all) 2 - 3,4,5 - same thing 3 - 4 - 3Ω 3 - 5 - 4,6Ω 4 - 5 - 3Ω Are these numbers something that I could expect from a transformer?
