I have never known the two 'U' ferrite cores to be actually glued together. They are normally just clamped together with threaded rod. There are very small paper gaping paper discs between the core faces.

They are usually stuck very tight with hardened wax and heat from the transformer itself. Take great care, it is very easy to snap off one of the arms if handled with force.

When I was a young lad I used to make Ekco and many other line output transformers including rewinding during the period 1961-66. [D&B Television. Wimbledon] No adhesive was employed and the transformers used to fall to bits once unclamped. This was the best part of 60 years ago and they are all now seized solid!

I can only suggest warmth and general easing. Good luck with it. John.
