LL1681 Trasformatore step up per testina MC (moving coil)

Rapporto: 1+1 : 13+13

Dimensioni: 48x29x20

- Mu-metal core

- Internal Faraday shield

Moving coil input 1:13 or 1:26 . Mu-metal core. Internal Faraday shield. For low and medium impedance cartridges.

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.
