Yamamoto Acoustic Crafts SUT-03 High impedance specification step-up transformer

The main feature of the SUT-03 is that the two transformers are completely separated from each other and sealed in a solid case, whereas a step-up transformer for two stereo channels is usually manufactured in a single case. The solid case is made by machining a block of aluminum alloy, enclosing the transformer unit in it and wiring it over the shortest possible distance. This case is impregnated with a high-strength, heat-cured, highly insulating, high-strength epoxy resin. The transformer case is anodized in a beautiful and age-resistant champagne gold color for a high quality finish. This ensures that the transformer unit is virtually unaffected by vibration and is free from the effects of minute vibrations, allowing even the smallest signals from MC cartridges to be picked up without loss.
The SUT-03 has a more aesthetic and richer sound while maintaining the cartridge's character. Instrumental performances and female vocals are particularly impressive.

The transformer unit of the SUT-03 uses a 100 micron thick Super Permalloy core, wound with Teflon insulation paper. The SUT-03 has a solid case that is virtually unaffected by vibration. On the back of the case, M2.6 screws are cut in the four corners, so you can use your own favorite base or other device to fasten it to these parts. The case can also be used to fasten a base of your choice, etc., to these screw holes when installing it inside an amplifier. The impedance of cartridges compatible with the SUT-03 is 5~40 ohms, and its amplification factor is designed to be 10 times.

How to wire the SUT-03
The ground terminal must be wired separately for left and right, so at least two ground wires are required. The ground wire coming from the player may or may not be connected to the transformer case ground terminal. Please choose the best one according to the system you are using.
