ZAIKA 300B single mono power amplifier. While increasing bandwidth, it has musical distortion characteristics centered around 300B's unique secondary distortion, and can be enjoyed regardless of genre with tuning that maximizes 300B likeness. The vocals are particularly good. The appearance is fine, with no noticeable scratches, etc. (Kobayashi Hitoshi)
