ZEROZONE 6N3(5670) Tube Buffer Preamplifier Bare PCB

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 +/- 1dBTotal harmonic distortion THD:> 0.005%Signal to noise ratio S / N: 95dBGain: ≈0dBBrand newinput voltage: AC 0--12V/1000mAReference tube model: 6N3 or 5670Size:113mm*65mm*63mm

NOTE: This is the Bare PCB. All parts need to be matched by yourself.
