** Please note, many tubes will test NOS but will actually have a few hours of use on them.

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. 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, less than 0.01% have gone missing.
