Electronic Vacuum Tube ShuGuang Treasure 6CA7-Z 6CA7 Vacuum Tube For Tube Amplifier Bakelite Base

Item specifics:

Type: Vacuum tube

Brand: ShuGuang

Model: 6CA7-Z

Country/Region of Manufacture: China

Description:

1.The Shuguang Treasure series 6CA7-Z tube sounds fantastic and looks great.

2. The 6CA7-Z tube's construction features gold grid wires and a new internally coated black glass bottle.

3. 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.

4. 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.
