I would first try the transformer just connected to the input volts,
and with absolutely no connections to the secondary, and see if it on
its own produces smell/smoke. That should be a start to determine if
the problem is the transformer at fault, or the circuit it is
connected to.

I assume you have checked the transformer to see there are no
insulation problems to ground from either winding, or between windings
?
