Ortofon ST-70 Transformer

Starting with high quality Lundahl™ transformers, surrounded by a specialized mu-metal shielding, the ST-70 is engineered from the ground-up to ensure that every detail in a complex array of notes is reproduced with utter purity, with freedom from internal and external sources of interference. Elsewhere inside the box, the dual-mono design provides discrete circuitry for each channel, resulting in the elimination of crosstalk and possible distortions.  This results in cleaner, clearer reproduction with substantially increased stereo imaging.  Regardless of the composition being played, the ST-70's expansive stereo separation provides lifelike realism, and accurate tonal balance devoid of coloration.

To further minimize signal degradation and maximize signal flow, the ST-70 has been engineered using a high-quality, industrial-grade PCB.  Additionally, gold plated RCA jacks with Teflon insulation provide optimal conductivity for use with high quality interconnects.

The ST-70 is compatible with a wide range of higher-end Moving Coil cartridges thanks to its two Gain/Impedance options, set using internal jumpers. But for those already using Ortofon Cadenza cartridges, the ST-70 provides the perfect technical and sonic match to the range.

We endeavour to despatch same day for orders placed up to 1pm on available stock items (items with stock message "Usually dispatched within 24 hours"). Please remember to check with us first for a physical stock check if next day delivery is important to you. Any items with stock message "Usually dispatched within 72 hours" are items that we do not hold in stock but order in from the importer or manufacturer as soon as a customer order is received. Occasionally these may be delayed beyond 72 hours due to importer/manufacturer stock levels but we will inform you as soon as we can if this is the case.
