What step up transformer do I need for a 0.5mV cartridge?

With a 0.5 mV moving coil cartridge, you’re in the sweet spot where you need a step-up transformer (SUT) that provides enough gain without overloading your phono stage. Many cartridges at this level perform best with ratios around 1:10, however 1:8, 1:12 and 1:16, depending on the input sensitivity of your phono stage and the cartridge impedance. The MC1 moving coil step-up transformer preamp is ideal here, offering flexible loading options and premium Lundahl transformer choices to let you fine-tune the match. Our online SUT Load Calculator makes it easy to model the effect of ratio and loading before you listen, helping you get the most from your 0.5 mV cartridge.
