Need matched power tubes? Don't worry! Price includes matching in any quantity you need for no extra charge. Need a matched pair? Just order "2" tubes. For a matched quad order "4" tubes. Matched sextets and octets are available as well.The Chinese (Sino) made Shuguang 300BC vacuum tube has good clarity, impressive bass, and good dynamics. It’s a little to the warmer side of neutral, and has both a deep and wide soundstage.
The Shuguang 300BC power tube has a unique solid high-purity graphite anode not seen in any other 300B. The grid wires are gold-plated and it sports a ceramic base with gold pins.
Be sure to read the great 300B tube review and comparison from the Wall of Sound.
