A transformer including a core; a concentric inner primary tube passing through the core and running up and over at least a portion of the core, the concentric inner primary tube defining a longitudinal axis within the core; and a concentric outer secondary tube passing through the core and running up and over the concentric inner primary tube, the concentric outer secondary tube defining a longitudinal axis within the core and being spaced apart from the concentric inner primary tube, the longitudinal axis of the concentric inner primary tube and the longitudinal axis of the concentric outer secondary tube being aligned with one another so as to be coaxial. The concentric outer secondary tube substantially encloses the concentric inner primary tube so as to provide a low impedance shield.
