This rare British DET25 / VT25 (Air Ministry designation 10E/7312) directly heated transmitting triode was manufactured by M.O.V. (Marconi-Osram Valve Co.) on May 7, 1936, for military and professional radio service, including communications equipment associated with the Royal Air Force. Developed as a rugged high-voltage member of the Type 10 triode family, the DET25 features heavier internal construction and wider electrode spacing than typical American VT25 variants. 

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.
