Archive Assessed, Apos Assured

All Archive tubes are thoroughly tested, inspected, photographed, and inventoried, guaranteeing the quality of each tube that's shipped to customers. All tubes carry an Apos 12-month warranty against manufacturing defects. 

Are the tubes...dusty...?

Because these are genuine New Old Stock tubes, small cosmetic irregularities may be present. These aren't defects but artifacts of vintage manufacturing and decades of storage. They have no impact on reliability or sonic performance.
