New Yamamoto

I still enjoy the english descriptions, especially the Siemens C3m valve ” various kinds of electrical properties are excellent, and it is the feature that sound quality is very beautiful.” We all knew the 300B sounded good, this is the first time I’ve come across the C3m driving a 300B.
