Description

NOS NIB new matched pair Sylvania 6AZ8 vacuum tubes in crisp original boxes, test in the new range on our calibrated Jackson 648A tester, may have light shop use. They are marked Sylvania in Sylvania boxes, but the 6AZ8 is in a hexagon with RCA type "U.S.A." over the hexagon, so probably are made by RCA for Sylvnaia. May have light shop use.
