Step-up transformer for monaural MC cartridge
Step-up transformer for low impedance monaural MC cartridges
Yamamoto Sound Craft SUT-02is a step-up transformer designed for low impedance monaural MC cartridges. With a design that completely separates the left and right transformer units and completely eliminates vibrations, it picks up even the smallest signals, creating a more aesthetically rich sound while preserving the individuality of the cartridge.
Complete isolation of transformer and optimization for low impedance
- Completely separate structure: The step-up transformer, which is normally housed in one case, is completely separated and enclosed in two aluminum alloy machined block cases. Interference between channels is completely eliminated, increasing the purity of the sound.
- Thorough elimination of micro vibrations: The inside of the case is impregnated with high-strength epoxy resin. The transformer unit is free from minute vibrations, making it possible to pick up even the smallest signals from the MC cartridge.
- Optimized for low impedance: Compatible impedance is**1Ω to 5Ω, amplification factor is 20 times (26dB)Set to **. This setting is ideal for modern high-output, low-impedance MC cartridges, and also has the advantage of making the preamplifier's volume level easier to use.
High-grade materials and excellent compatibility
- Core and insulation: The transformer unit uses a 100 micron thick super permalloy core and is wrapped using Teflon insulating paper.
- Simple winding: There are no taps in the winding, and there is only one wire for both input and output, thereby suppressing the deterioration of the SN ratio due to loose terminals, and pursuing high sound purity.
- Compatibility: Yamamoto Sound CraftNot only is it the best match for the original cartridge YC-02, but it also works great with low impedance masterpieces such as **Ortofon SPU**.

Optimized for overwhelming silence and low impedance
"Overwhelmingly quiet, picking up every minute signal."
The SUT-02's most distinctive feature is its design, in which the machined aluminum case is completely separated and impregnated with epoxy resin, completely freeing the transformer unit from minute vibrations and resulting in overwhelming silence. This makes it possible to pick up extremely small signals from MC cartridges without noise, and is said to dramatically improve resolution and sound field depth.
"The optimal solution for low impedance/high output MC cartridges."
The compatible impedance is 1Ω to 5Ω and the step-up ratio is set to 20 times (26dB), making it ideal for recent low-impedance/high-output MC cartridges. By suppressing the boost ratio, the volume on the preamplifier side is easier to use, making it easier to balance the sound.
"More aesthetic and rich sound. Great combination with SPU."
Like the SUT-03, it has been praised for its ability to create a more aesthetically rich sound while preserving the individuality of the cartridge. Especially**Yamamoto Sound CraftIt works wonderfully with not only the original cartridge YC-02**, but also with famous machines such as the Ortofon SPU, bringing out the lustrous expressiveness of musical instruments and female vocals to the fullest.
