The whole body has been fully maintained! A power amplifier with a die-cast chassis that performs all stages of Class A operation. Contrary to what it looks like, rugged sounds are fine and stretchy. It achieves both the delicate reproduction and thick sound quality typical of Class A amplifiers, and plays vocals and classical music smoothly. There is a crack in the speaker terminal cover. There is a lot of feeling of use such as rust and dirt on the exterior (Murakoshi Yoichi)
