This is a Special Order item.

Due to circumstances relating to this product, it is only available in the UK to special order, which means it is not stocked as standard in our warehouse. A special order item will be placed on order with the relevant manufacturer during our next scheduled Purchase Order. As we forecast orders up to two months ahead of time with some suppliers, this does not mean the item will automatically be included on the next shipment we receive. It also does not mean that the item will immediately be placed on order with the supplier, as we group special orders together for logistical purposes. Therefore, we estimate lead times on most special order items of 8 – 12 weeks.

No other company has ever retained a phono cartridge model in their product range for so many years. The SPU was used by early broadcasting companies among whom the Ortofon brand name was already well known from the first moving coil system - the Ortofon mono system in the small black A-housing. The so-called “Ortofon sound“ became synonymous with the sound from the SPU, at an early stage.

The SPU #1 S is a Moving Coil cartridge with an 18 µm spherical stylus profile.

The SPU series embodies the essence of the original Moving Coils and are a perfect solution for the playback of both early and modern and contemporary stereo recordings.

For moderate and high mass tonearms with SME connections.

This item is available to Special Order.
