Lamination problem: I suspect that you're correct. But you said "didn't have time, etc." Presumably, that was because of the over-heating resistors on the secondary winding. However, what we (or certainly myself) would like to know is what is the primary current (at full input voltage to the primary) when there is
no load on the secondary.
Sometimes, loose lams. can be fixed by adjusting the bolts that hold the xformer together and similar mechanical considerations. Perhaps some additional clamps? May be worth spending some time investigating that line before condemning that xfromer permanently.
