Ortofon St-7 Transformer

Compact and stylish, the ST-7 has a solid housing supported by four rubber feet, which helps to reduce unwanted vibrations in the unit.

High-quality internal wires together with high-quality gold-plated terminals provide the optimum signal transmission. The sandwich winding structure, used in the ST-7, significantly improves the high-frequency response and provides a very clear and open sound over the whole frequency range.
 
Additionally, the dual-mono design, including the individual shielding of the two channels, improves the imaging of the transformer and reduces the influence of environmental noise. The ST-7 transformer will be a perfect match for, among other MC cartridges, the MC Quintet Series, the SPU Classic models, and SPU #1 models.
