Ortofon ST-7 Step Up Transformer

The ST-7 marked the return of Ortofon producing more affordable step up devices. Housed in a small but beautifully made metal enclosure, the ST-7 features sandwich winding in the transformer which is claimed to significantly improve the high frequency response and provide a very clear and open sound over the whole frequency range.

High quality internal wiring is used to join the transformers to the gold plated sockets.

Permalloy shielding is used to reduce the chance of hum pickup from surrounding pieces of electronics equipment and also help to prevent interaction between the two channels, which helps improve stereo separation.

With gain of 24dB and suitable for cartridges with impedances spanning 2 Ω to 60 Ω, the ST-7 transformer is a perfect match for many cartridges, including the MC X, MC Quintet Series, SPU Classic models as well as many from other manufacturers.
