Are you looking for a premium KT66 tube for your vintage Quad II mono blocks? Consider the Shuguang Treasure series KT66-Z tube. This KT66 sounds fantastic and looks great too.



The KT66-Z tube's construction features gold grid wires and a new internally coated black glass bottle. This unique HPCC coating is known as High Polymer Carbon Compound glass coating and is unique for its ability to reduce stray electron emission that can otherwise reflect off the glass. 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. This new Shuguang Treasure series required additional parts selection quality control processes, improved vacuum techniques and additional burn-in time and testing. This Shuguang Treasure KT66-Z tube is their premium export grade and purchased direct from Shuguang in China.
