LL7902 Lundahl trasformatore d'isolamento

LL7901 and LL7902 are large size, high level, high performance audio transformers, made for extraordinary requirements. The LL7901 has an extreme level capability ( + 34 dBU @ 50 Hz) while the LL7902 combines high level capability (+28 dBU @ 50 Hz) with low copper resistance. The transformer 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 transformers are magnetically shielded by a mu metal case.
