To U.S. Buyers:
Due to recent changes in U.S. import tariff policies, we now include import duties and customs processing fees in the shipping cost.
The shipping fee consists of customs duty + customs clearance fee.
In some cases, we may be able to offer a discount on the above amount, so please feel free to contact us for details.
To Buyers Outside the U.S.:
Customs duties are the responsibility of the buyer.
If shipping costs apply, they cover regular transportation fees only.
In either case, please feel free to contact us with any questions about the item.
This is a set of four Toshiba 12AU7 Hi-S tubes for general testing. One tube has slightly brown lettering, possibly indicating a different production period. One tube comes in a white box. All four tubes have been measured with a vacuum tube tester for GM values. The standard reference is 2200, and all exceed this value. The measurement results are labeled on the tube caps with tape. Some amplifiers may produce a “pop” sound on power-up, depending on compatibility; please note this is normal.
