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.
