The Siemens ECC81 tube is also known as the 12AT7 tube in North America. This German-made ECC81 model is both rare and of vintage European quality. These were acquired still in their original bulk packaging dated 1961. The digit located in the glass at the base of the tube (a characteristic of Siemens) also verifies their origin.
