What the evidence preview establishes

Mechanical shock fractured the transformer bobbin, while solder balls on exposed windings likely created shorts and reduced inductance.

Why this case matters

Check mechanical restraint, lead loading, and solder-splash control when transformer voltages and inductance are abnormal.
