About this tube
 
     The auction is for one tube.Frankly speaking,Shuguang Corporation doesn't have 12AU7 matched because they think they are small tubes and that products with the same batch will have similar data.We directly ship the tubes from SHuguang Corporation and we don't match them by ourselves which is not correct,of course.
