Each country of origin of manufacturing has different Tariff rate. For example. U.K origin will pay 10%. Please find out this rate yourself. Shipping to non-U.S. is tariff free. You do not pay anything. 
Most of my tubes were U.S. made. So, you are free of tariff if shipping to U.S. Thanks for the attention.
Due to the new 35% U.S. Tariff on all items shipped to the USA, Buyer will pay for this new burden. My prices have been lowered to the minimum, and cannot be jeopardized by this new tariff, hope buyers will understand, thank you.

One lot of 4 assorted 12AX7 tubes by GE, RCA and Signet. The Signet is of Japan origin. Some new and some used.

Test Ratings: 130/130, 100/105, 100/100 and 95/95 on my Jackson 648s tester, minimum is 70, new tubes at about 105-110.

SHIPPING: Shipping to USA and Canada with tracking. But shipping to International countries will be with no tracking, to save you about $20 and more, depending on the particular country.

Combined shipping saves money.

Please pay in 3 days. Combined shipping is welcome. If you have paid for individual items and have surplus shipping fee paid for, I will refund you immediately when I send out the combined parcel.
