Description
Microphone Input Transformer
LL1528
LL1528 is a Lundahl microphone input transformers built up from two coils, each with one primary and one secondary
section separated by a electrostatic shield. The core is a high permeability mu-metal core, and the transformer is
housed in a mu-metal can.
