Audio Note AN-S3H Moving Coil Step Up Transformer
All Audio Note™ MC transformers are housed in solid copper chassis for best sound. Despite this, and like most SUTs they are quite sensitive to positioning, and hum will occur when they are too close to power cords, supplies or electric motors and their associated wiring (from a separate turntable power supply to the turntable itself for example), so careful positioning is mandatory. That said, I’ve found it easy to get hum-free operation with this SUT.
The transformers are wound on fully interleaved mu metal cores with very high quality copper wire. This H version has 22dB of gain (12.6 x voltage ) and 64 ohm input impedance, suitable for cartridges with coil impedance of 16-21 ohms.
