AC12V / 1000MA 6n3 Electron Tube Buffer board Biliary Front amplifier board
Tube buffer can be seen as a gall previous level, but it is slightly less than 1 magnification, the gain is approximately equal to 0dB.
It can play a role in better impedance matching (increase input impedance, lower output impedance and better after the driver stage)
Tube buffer can effectively filter out the remaining digital signal sources, so warm and mellow, soft Naiting!
You can replace yourself with the following more common type pipe also experience different styles tube: 6N3,5670,6H3, and so on.
6N3-Buffer Amp Specifications

Another feature of this buffer is the supply requirements are very simple, requires only a single 12V / 10W transformer, screen voltage, filament voltage all set. Followed by good audio input, and audio output cable can work! !
