Shuguang also uses their new "Super Alloy" technology. Originally applied to aviation, aerospace, and military applications, this technology has been successfully used by Shuguang to accomplish directional solidification and single crystallization. This greatly improves the ability of electron emission and electron current stability. The Shuguang Treasure tubes required additional parts selection quality control processes, improved vacuum techniques and additional burn-in time and testing. These Shuguang Treasure tubes are their premium export grade and purchased direct from Shuguang in China.
Some of these tubes are packaged in boxed sets of two (matched pair). You need to order "2" tubes to receive this boxed set. If you order "4" tubes we will send a Matched Quartet whenever possible.
If you need one tube select "Single - White Boxed". When this option is selected we will send an un-matched tube in the quantity ordered.
