Ortofon Hi-Fi MC Transformer ST-80 SE Step-Up Transformer

The ST-80 Special Edition Moving coil transformer delivers a detailed reproduction with a touch of warmth accompanied by a full bodied sound quality. Compared with existing models, ST-80 SE has a larger bobbin, more layers in the permalloy core and more coil windings.

Lead time 41 -49 days. This is a special order product. Delivery timelines are an estimate only and will be confirmed after your order has been confirmed.

Manufacturers Details:

The transformer is magnetically shielded in a permalloy case, which in turn is inserted into a robust 10mm thick aluminum cylinder bored out of a solid aluminum block. Together with the heavy metal case the transformer effectively isolates against environmental noise.

Engineered With Care:

The stability of the transformer is superb thanks to its substantial weight of 1.5 kg, ensuring it stays in place even when cables are attached.

Key Features:

The ST-80 SE is built as a pure dual mono model, which ensures maximum channel separation. Internal point-to-point wiring is made by Teflon insulated, solid-core pure OFC copper-wire plated with gold. Together with high quality gold plated RCA jacks with Teflon insulation that ensures the optimum signal transmission and integrity.

The ST-80 SE will be a perfect match to most high quality MC cartridges, such as the Cadenza series, Xpression, MC Anna, MC A95, the historical MC A90 and MC Windfeld, as well as the SPU cartridges.
