LL1678 is an input audio transformer for moving coil pickups. The transformer is built up from two coils, each coil with one secondary winding surrounded by two primary windings. This structure results in an excellent frequency response. All winding ends are available on the pins. Thus, the transformer can be used with a set of different turn’s ratios.

The LL1678 is made with amorphous core material. As this type of core does not store energy (unlike e.g. conventional mu-metal cores) the low frequency resonance with external series capacitors is practically eliminated.
