This is true for a transformer that is not or normally loaded. But when
it is overloaded, we can get a behaviour similar to a coil: the
saturation is fixed by the current, not by the voltage, due to the
knee of the hysteresis curve. That imply the voltage drop will not only
be a function of the resistive losses, but also of the saturation of
the flux in the iron.

The Mace have silicon rectifiers. And the supply voltage drop on the
output transformer was at least of 100V, that between the full volume
point (160 w with a clean sinus, I know its hard...), and the fully
saturated point, when at the same time, the output power was almost the
same. At the output, the voltage was dropping with the saturation.
I don't think resistive losses alone can explain such a huge voltage
drop on the supply voltage.
