Psvane Black Treasure CV181-Z, / gold Grid / HPCC coating / Super Alloy Matched PAIR

The 6SN7-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

PSVANE also uses its new "Super Alloy" technology. Originally applied to aviation, aerospace, and military applications, this technology has been successfully used by PSVANE to accomplish directional solidification and single crystallization. This greatly improves the ability of electron emission and electron current stability. The PSVANE Treasure series required additional parts selection quality control processes, improved vacuum techniques, and additional burn-in time and testing.
