Boost transformer for 1990's Orthophone SPU. The core was carefully selected from the specially ordered Hi-Mew Super Permalloy with high magnetic strength for the first time and used. If the impedance is low, it is compatible with various cartridges. Dullness and a feeling of use can be seen. (FUJISAWA KOSHI)
