The EMT STX 5/10 is a Swiss-made, hand-built moving-coil (MC) phono step-up transformer. It uses toroidal transformer technology, 99.99% silver wire, and a very-low-loss magnetic core alloy. It provides two selectable transformation ratios: 1:5 for +14 dB gain and 1:10 for +20 dB gain. The EMT setting is intended for matching EMT cartridges, while the Open setting provides a higher effective input load for other low-output MC cartridges. Grounding can be configured as center-tap, floating, or input-cold. Available manufacturer and dealer information indicates that the STX 5/10 remains a current product rather than a discontinued model.
