Attenuators, insulation bushings, etc. have been replaced with new ones in 2018/11! The resistance value is lowered as much as possible by carefully polishing the terminals where the conduction is conducted. With a crossover of 7000Hz, it is ideal for tweeters such as 075 and 077. The appearance may be dull or deteriorated. Serial 19618/19692 (Satoshi Yonejima)
