X-Y applications

I pulled apart the 'bad' NOS eBay yoke.. It was not hard to take apart but I cracked a ferrite a bit. I don't think it will harm anything if I super glue it back with no voids.

I'm looking at the windings and can see how a pinboard template could be made up using the original windings, flattening them out as they might have been during some manufacturing stage, but they are made with a lacquer so they might not want to flatten easily.

Once a pinboard template is made that defines the inner and outer size of a particular winding (H or V), then a few more pins can be added so that I could wind a few turns of heavier wire on the board for the new coil. The method is shown in MIT volume 22, p. 717 and described in the text. It looks easy but probably won't be.
