Golden Voice 211+

GV 211+ is an enhanced version of the normal 211, the tube base and workmanship is better, improved graphite plate impurity treatment process to extend the product life, the structures of the mica plates is different older vserion. The performance can reach the mid-range product level of the current market, and the price is very competitive.

GV 211+ is direct-heated type thorium tungsten cathode triode, can be used as class A, B and C.
