It appears that the E's and I's of the core are not = interleaved so all I need to do is cut the weld holding the core together a= nd it should fall apart. Hopefully in just two pieces. Then I can strip out= the windings, put my own winding on, and, most importantly, sandwich a spa= cer so I have a gap (I said this was a DC choke). Anyone here ever play with microwave oven transformers at this level and le= arned any hard lessons?
