Product description:
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.
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! !
Frequency response SFR: 10Hz-40KHz +/- 1dB
Total harmonic distortion THD:> 0.005%
Signal to noise ratio S / N: 95dB
Gain: ≈0dB
Brand new
input voltage: AC 0--12V/1000mA
Reference tube model: 6N3 or 5670
Size:113mm*65mm*63mm
NOTE: We have DIY kit or Finished board (Optional)
◆ DIY kit ---- All parts need you to solder and test it.
◆ Finished board ---- All parts have been welded and tested OK.
