JSDZ DIY Kit 6N3 Tube Buffer Amp Audio PreAmp Amplifier Board

Product Description The buffer will 6N11 tube horizontal mounting, especially for low chassis installation, power requirements are very simple and requires only a single 12V / 10W transformer, rose through the onboard screen very needed boost line voltage. Followed by good audio input , and an audio output cable can work! ! The buffer sophisticated materials, PCB solder black using advanced dual-panel, input and output coupling capacitors chosen selection of original Philips BC400V2U2 boost capacitor units produced LELON Lvpao 220UF / 50V electrolytic, input and output terminals using strong solid metal RCA, this buffer layout is reasonable, nice shape, is your upgrade. installed the best choice! Feature Kit Installation Note: Resistance PCB board is not marked, please install the following: 12k R1,R2 470R R3,R4 470K R5,R6 Usage: audio source -> The buffer -> PA Buffer tube preamp is actually a gall bladder, but it's slightly less than one magnification, which is not Amplification, the gain is approximately equal to 0dB. It can act as a better impedance matching (to improve the input impedance and reduce the output impedance of the driver stage the better) Tube buffer can effectively filter out the residual digital audio signal, so warm and mellow, soft Naiting! You can also replace their more common following the same model tube: 6DJ8,6922, ECC88,6H23 so on. Input impedance: 500K Ohm Output impedance:> 10K Ohm Input Sensitivity: 200mV Gain: 0dB Frequency response: 10Hz-40KHz +/- 0.5dB Total Harmonic Distortion:> 0.005% Signal to noise ratio:> 100dB Input: RCA × 1 group Output: RCA × 1 group Dimension: 134mm × 89mm × 35mm high Weight: 180g Other substitution of the same model can pipe: 6922 / 6DJ8 / ECC88 / E88CC / ​​6H23 ...
