The Shuguang WE 300B tube has exactly the same electronic and mechanical specification as the original Western Electric WE-300B tube.
Audiophiles have been waiting years for the Western Electric company to produce more of their great 300B tubes. In the meantime every 300B produced by other manufacturers attempts to meet or surpass the sound of the famed WE-300B. Thankfully Shuguang has arrived with a close replica of the original. It is copied from the plate, micas, base, and bottle.
Matched and tested by factory and one year warranty.
