Transformer is custom made, hand wound.

To start, you'll need:

  1. Ferrites: 2pcs of TDK B66305G0040X127 (E13/7/4 core halves, material N27, 0.04 mm gap)
  2. Coil Former: B66306C1010T001
  3. Primary: 0.3mm diameter enamel wire
  4. Secondary: 0.1mm diameter enamel wire

Instructions (warning: CRAPPY PICTURE QUALITY :( )

You're done with the primary winding. Now onto the secondary.


Again, sorry for  the eye-cancer-inducing photos, these will have to do the job. For any questions, please write!

oh sweet, gonna make myself some transformers now :D

if time permits maybe you can go a bit into details on how you come up with the number of turns for primary/secondary, how was the wire diameter calculated and so on.
