※Maintenance has been carried out, but there is some residue left. The rare 70's Pioneer control amp has a slightly narrow range, but the glossy way it rides feels like a pioneer. It has few quirks and seems to be domestically produced, and I like the slightly serious sound construction. It's a must-see, especially for those with an SM-850 power amplifier of the same age. There are stains on the exterior as a whole (Murakoshi Yoichi)
