High Impedance Line Input transformerfrom the renowned Lundahl Transformer company.
The LL1531 consists of two coils,each with one primary and one secondary winding separated by an electrostatic shield. 
The two secondary windings are internally connected in series.
The core is a high permeability mu-metal lamination core.
The transformer is magnetically shielded by a mu-metal housing.
Being a high impedance transformer, the LL1531 should normally be used with primaries connected in series
