Quantity

The LL1681 is a large core moving coil input transformer with a mu-metal core.
The LL1681 consists of two coils, each with a two-sectioned primary winding and one high level secondary
winding (with paper insulation) separated by electrostatic shields.
The transformer is magnetically shielded by a mu metal housing.
