Keep in mind, if using MuMetal sheet; If it has to be bent(to
any great degree), annealing in a hydrogen atmosphere is
recommended, to restore the grain structure/permeability.
MuMetal foil is also available, if you can arrange a way to
surround the transformer with it. The foil doesn't require
annealing, unless severely formed or heliarced. One source:
