Description

In 2020, Mr. Sugano Jr. resumed the production of the acclaimed Koetsu step-up transformer due to repeated requests from customers. If you hear it matched with the Koetsu range of cartridges, it is easy to understand why there was so much demand for this hand-made supremely crafted transformer. Explore the full sonic potential of your Koetsu MC Phono Cartridge with this high-quality Japanese made transformer which delivers gain with high-efficiency energy, naturalism and purity. By reducing signal loss with low internal resistance, this transformer supplies the gain to the preamplifier that MC cartridges need to produce clear, open, airy, nuanced, and detailed sonics all the while lessening noise and grain.
