Brand New, MINT NOS BRIMAR ECC82 12AU7 1970s HALO-DISC Getter tubes with short plates. MAZDA LABEL Thortn-AEI production. Made in ENGLAND. Copper Grid Posts. Highly desirable Brimar 12AU7 type.
This is the first time we have seen Brimar Thorn-AEI 12AU7 tubes with halo getter with disc. Otherwise tubes are the same as Mazda or Ediswan label short plate tubes from Brimar Thorn-AEI.
Tubes are definitely British Thorn-AEI production but have Foreign BVA label on the back. Also the etched codes are wiped out. This could be intentional to meet some tender requirement or could be an error.
