Silver Wire Moving Coil Input Transformer LL1933Ag
LL1933Ag is a silver wire version of our high performance moving coil step-up transformer LL1933. The LL1931Ag combines our dual coil structure with high purity (99.99%) silver wire in an oversized design. The core is a mu metal lamination core for low distortion and for a linear magnetization curve. The dual-coil structure greatly improves immunity to external magnetic fields from power supplies, motors etc. The transformer is housed in a mu-metal housing.
