Custom-made! A fully balanced preamplifier that uses 4 x 300B, is a rare item. Equipped with transformer type contact attenuator, no phono, line only. The freshness and goodness of sound is attractive. There is a slight increase in volume. The appearance is not particularly big noticeable scratches* Because it uses 4 300B, it generates heat, so please make enough space for heat dissipation and use it (Tetsuji Oikawa)
