A kit model of a power amplifier using a 50CA10 3-pole output tube and an OY15 type output transformer, composed of circuits and parts conforming to the MQ60 type, which has been evaluated by LUXMAN. The sound of a vacuum tube has a sense of volume that seems to meet expectations, and it gently envelops you. The sound, which doesn't require scale, is particularly unique, and the slight thickness that spreads from below the mid-range makes you feel comfortable. The exterior is dull, rust, abrasions, etc., and there is a feeling of use (Ryo Mizusaki)
