The Psvane WE845 is a hybrid creation by combining the characteristics of both RCA845 and WE284A tubes. The first Psvane WE845 prototype was sent to Japan in late 2012 for evaluation and the reviewer commented: ‘It’s an ultimate pleasure to re-live the RCA845 sound from Psvane WE845 and I hope you can improve the sound to the WE284A level.’. Psvane design team took another 8 months to improve on design then we come to have today’s final version of the WE845 Replica.
According to the manufacturer Psvane Audio, the Psvane WE845 can replace all current production 845 tubes in high end audio application.
We strongly recommend users to follow your amp manufacturer’s suggestion in tube substitution and bias adjustment to ensure safe use of high voltage 845 tubes.Measurement: (in mm)
Below is the size measurement of the Psvane WE845 tube – there is a glass tip on top of Psvane WE845 tube, so please take into account of the overall height if your amp has a tube cover. In terms of glass enclosure diameter, the Psvane WE845 is of same diameter as Shuguang 845B tubes (the most widelyused 845 tubes in new production 845 tube amplifiers) and it is slimmer than the Psvane 845-TII (which has a wider diameter glass enclosure).WE845 is direct-heated type thorium tungsten cathode triode, class A1 and AB1
