845 SE tube amplifier pure class A output 20W/channel No Negative Feedback
Our target is not to chase arbitrary bench measurements for the sake of specifications alone, even though our amplifier comfortably outperforms most standard products on the market. While we possess the engineering capability to force even lower distortion figures on paper, we deliberately choose a different path.
Our true focus is the emotional energy and vitality that music conveys, which can not be calculated by any machine, rather than achieving the lower possible THD or the wider frequency response. To capture the true soul of the music, we willingly accept trade-offs in conventional technical data when it serves the ultimate listening experience

845 SE tube amplifier pure class A output 20W/channel.
This amplifier use 6J7 ( you can use 6J7G, EF-37 or WE348A also) in prestage. Driver stage use 6SN7 to drive 845 tube.
Input is RCA, XLR is option, you can choose input transformer for your balanced input XLR.
This use fixed bias. There is current meter for monitoring plate current on 845 tube real time. You can also change bias current on 845 by bias volume adjuster.
No NFB was adopted, the hum level is only 0.3mV. Sound is powerful, clear, sweet and detail with all characteristic of 845 tube.
With 20W per channel, it can drive almost speakers without problem.
Previous stage is 6J7G, driver tube is 6SN7, 845 current is about 70-80mA.
Response frequency : 16Hz - 30KHz
Hum level : 0.3mV
THD: 5% @ 20W/channel
