The inductive ballasting effect of the magnetic shunts is eliminated.

The core either has a magnetic shunt, or a gap in the iron core, both of which serve to current-limit the output, allowing them to run indefinitely in short-circuit conditions.

MAGNETIC SHUNT: Outcome of meeting between rival and highly competitive British amplifier designers when both parties simultaneously misplace their bifocals.

The standard traditional neon transformer, a magnetic shunt transformer, is a special non-linear type designed to keep the voltage across the tube raised to whatever level is necessary to produce the fixed current needed.
