** Please note, many tubes will test NOS but will actually have a few hours of use on them. A truly NOS tube will have excellent getter flashing condition, no dirt/grime, usually in the original box, and no filament deposits. If a tube is listed as "tests NOS" but is listed as "not True NOS" please expect the tube to have a small amount of use *
All tubes have been tested using only the best tube testers. We have a large fleet of tube testers, and every single one of them has been calibrated within the last year by industry experts. We mainly use the Hickok TV-7D/U, but occasionally we may use a Hickok 539, 533A, or 600A.

INTERNATIONAL CUSTOMERS - READ
ALL international orders will be shipped by USPS First Class Mail International by default, which is the cheapest method at $9.99. This shipping service is very cost-effective, but you will not be able to track your package. It usually takes 3-6 weeks for a First Class Mail International package to arrive, but can take UP TO 3 MONTHS FOR DELIVERY.
We guarantee all of our shipments, but we do ask that our customers wait 3 months before we grant a full refund due to a lost package. We have shipped thousands of items internationally using First Class Mail and while we have had plenty take months to arrive, we have almost zero packages ever go missing.
