Yamamoto Sound Craft SUT-02 Low impedance specifications

The biggest feature of the SUT-02 is usually stereo 2ch. A fraction of the boost transformer is produced in one case, and the two transformers are completely separated and each is enclosed in a solid case. The aluminum alloy block is sharpened to make a solid case, and the trance unit is enclosed there and wired at the shortest distance. In this case, high-strength heating curing type high insulation, high-strength epoxy resin is impregnated. The transcase is beautiful and has a champagne gold color anodized finish with a high quality finish. This allows the transformer unit to be free from the effects of fine vibrations and to pick up the extremely small signal of the MC cartridge without excess.

The SUT-02 transformer unit adopts a 100 micron thick super permaloy core and is wrapped using Teflon insulated paper. In addition, the winding of the transformer does not tap, and the deterioration of the SN ratio by the play terminal is suppressed as only one input and output. A solid case was adopted so that the SUT-02 was hardly affected by vibration. On the back of this case, there is a screw of M2.6 in 4 corners, so you can stop the base of your choice in this part by yourself. You can also use this screw hole to stop embedding it in the amplifier. In addition, the impedance of the cartridge conforming to SUT-02 is 1-5 Ω, and its amplification rate is 20 times. This is because the recent low impedance type MC cartridge has a relatively large output, and the boost ratio is set slightly lower. This makes the volume level of the preamp relatively easy to use. The SUT-02 is not only the best match for the original cartridge YC-02, but also the Oltfon SPU. With the unique character of the cartridge as it is, the sound is more aesthetic and rich. Instrumental and female vocals are particularly impressive.
