Like the 211 tube, the Shuguang 845 tube is a transmitting triode tube that combines wall shaking power and great sound reproduction.
The Shuguang 845 is fast and clean sounding, with good tonal balance with a slightly forward midrange. It has good detail and smoothness, but a little edge in the midrange. This tube is the choice of most OEM's requiring the 845 tube. Great amps such as the Cary CAD 805, Aries 845-G monoblocks, Unison S8, and many others use this 845 tube.
The Shuguang 845 tube has a thorium-tungsten filament.
