New Old Stock in original box. Very rare Valvo Labeled (Siemens made) vintage German made tube, these are similar to the Telefunken Cca. The Cca is one of the "Holy Grail" tubes in the 6922/7308 family, and probably the best audiophile 6DJ8 type ever made, at any time. Labels in very good condition, and these are all Siemens-Halske factory marked, hey have the wide getter support with the crease in the middle. These are VERY scarce in the USA, especially in matched pairs.
