A step-up transformer made by Western Sound Ink using a VIEWLEX transformer. It seems to be for high impedance such as the DENON DL-103. I auditioned it with ortofon SPU-GE, but it was a fine and thick sound (Yoichi Murakoshi)
Maintenance information: 2022.5.6 sound confirmed
Accessories: None
Main specifications: primary side 50Ω, secondary side 75KΩ
