Shuguang Black Treasure KT88-Z Gold Grid - Matched Pair | Powertubes: Pentodes

SHUGUANG KT88-Z Black Treasure / gold grid / HPCC coating / Super Alloy

 

The KT88-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 KT88-Z tube is their premium export grade product. Purchased and shipped directly from Shuguang factory to  TAD, Germany..
