I can't give a definite answer to that... different properties of the core material perhaps, other transformer rated for 50/60hz and replacement 60hz. Dunno

Thanks for your input!!

Looking back at the pictures at the start, the windings are series connected to derive the split (-/+) rails. You have to stick with that arrangement.
