Maintained! Yamaha's finest tuner with all its luxury. It was equipped with a 7-row vari-controller, which was the first in the world at the time. The reception sensitivity is high, and it has an honest natural sound typical of the company, and I feel the appeal of not getting tired of listening for a long time. Serial 1554 (Takasaki Atsushi)
