Maintained! This is a heavyweight premain amplifier manufactured by PIONEER. Since they are only from the bubble period, large quantities of material were used, and they are highly cost-effective amplifiers. Even the smallest sounds are clearly reproduced, and the sound quality, which is both thick, shows how well crafted it was unique to that time. There is a feeling of use on the exterior, such as dullness and small scratches. Serial HH1004535 (Hiroki Aso)
