The LL7903 is a large, high level, high performance audio transformer, made for extraordinary requirements. The transformer combines high level capability (+28 dBU @ 50 Hz primary level) with low copper resistance and is designed for the most demanding applications. The LL7903 consists of two coils, each with two primary and two secondary windings separated by electrostatic shields. The core is a high permeability mu metal lamination core.

Turns ratio: 1 + 1 + 1 + 1 : 2 + 2 + 2 + 2

The transformer is magnetically shielded by a mu metal case.
