Silver Wire Amorphous Core Moving Coil Input Transformer LL1931Ag
LL1931Ag is a silver wire version of our high performance moving coil step-up transformer LL1931. The LL1931Ag combines our unique uncut amorphous cobalt core and our dual coil structure with high purity (99.99%) silver wire in an oversized design. The objective is to provide the best possible MC transformer, cost-no-object. 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.
