It must be some sort of physical attribute. The way they are wound,
insulation, etc.
Is there a way to tell using just an oscilloscope? I'm just
curious. I am very happy with the way my tube amp sounds.
Thanks,

The capacitance of the windings will limit the high frequency response.
Perhaps the best will have the secondary wire in parallel with the
primary wire. Never had one to take apart.
