Ratings & Reviews
Physical characteristics unacceptable
I purchased one of these Chinese 12AT7's and found that although the tube tests OK, It is physically taller and a larger diameter than a comparable USA 12AT7 tube. This made it unusable in a shielded socket...the diameter was larger than the metal shield wall.
