HP 9845B Power Supply Unit

Hi, a recently acquired HP 9845B desktop computer came with a literally broken power supply unit. One of the ferrite core transformers has a broken core. The lower, U-shaped core part is broken in the middle into two parts. Both parts are still there, rattling around in the coil part / transformer fixture. I do not think that I could find a new matching core. I am not sure of the magneto-electrical requirements and would like to hear about your experience or opinions: - should I glue the broken ferrite core with e.g. super-glue or epoxy (of course with ideally zero or minimum gap between the halves) ? - would it work or are there better ways to fix broken ferrite cores (e.g. adding a steel wire insert or something like that?) Thanks, Martin Hepperle
