Tubes (Matched Pair)
The CV181-Z tube construction features gold grid wires and an internally coated black glass bulb. This HPCC (High Polymer Compound Carbon) coating is unique for its ability to reduce stray electron emission. Shuguang also uses its Super Alloy technology to achieve better current stability.
This tube can be used to replace 6SN7 tubes.
