So with high B+ current, the xfmr is saturated, less bucking, lamp is
bright? That means the bulb dims when on station? Ken

Core saturates, and windings lose their inductance, basically becoming
purely resistive (only the wire winding DC resistance with no reactance),
the light would be brighter.

The problem with this explanation is that the two secondaries appear to
be connected so that they "buck" one another. If that is the actual
case then the reactance of the two series connected secondary windings
wouldn't change much with transformer saturation.
