Murasakino MT510 low impedance MC step up transformer

Here is the latest, and just updated Murasakino MT510 product info. This new MC transformer is designed for low impedance MC cartridges, that have an impedance of 12 ohms or lower and can be combined with most low-impedance MC cartridges. The first shipment is scheduled for summer (around June) due to the waiting for the production of special parts.

The Nobala MC transformer is already commercially available. Nobala uses the most ideal structures and materials and compromises nothing. We have the utmost confidence in this product. Specifically, when Nobala is combined with our MC cartridge, Sumile, they become most effective. Of course, Nobala is highly effective with cartridges other than just our MC cartridges.

However, much time and effort were spent on multiple tests to perfect the Nobala and Sumile combination.

Taking design into account, we developed the MT510 so that it can be combined with as many cartridges as possible.


This is an important part used to protect weak signals from a cartridge. The MT510 protects signals in a three-layer structure (as it does in Nobala). The transformer is covered with an aluminum plate. This in turn is covered by a 1.6-mm-thick iron enclosure (though the base is 2.3 mm thick). Furthermore, this is all protected by an aluminum panel with a thickness of 8 mm.

Parts used

Terminals for signal input and output were NEUTRIK RCA connectors. The grounding terminal is the same as those in Nobala. The transformer is different from that of Nobala and was newly designed for the MT510. Manufacturing of the transformer and processing and assembling of the MT510 are all performed in Japan.

Controlling sound with damping material

The transformer within the enclosure is fixed with damping materials. This suppresses the sound of metal (squeaking).

The MT510 is designed to be highly resistant to external noises. This would be useful, for example, when the power supply unit of a turntable is nearby.
