One Used Working Lundahl LL7903 Mic Input Transformer And One w/Broken Pin. 

Both of these transformers are used. The good unit has been fully tested and works properly. The other unit has a broken pin that I tried to repair, without success. Maybe you'll have better luck, or it could be used if you don't need the 1-2 coil section of the transformer. A copy of the data sheet will be included.

The LL7903 is a 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. The transformer is magnetically shielded by a mu metal case.
