HIFI 6J1 Tube Amplifier Board Preamp Bile Buffer Preamplifier Audio Board

Description: This product uses 6j1 tube to do lm1875 , with amp function. After 6j1 tube buffer, can significantly reduce the \"digital taste\" and \"quot;, so that the whole sound system to bring a \"bile\", the sound is more sweet, soft. Than the average lm3886, tda7294 better listen.The is the use of 6J1 fever tube gall bladder before the class: machine music 10D circuit principle design, to be reasonable to , more stable than the machine performance, the tube to play increased by 10 percent.This machine uses 18v input, do not have to worry about looking for high voltage The board comes with boost to in the low to enjoy the charm of tube.Power works: a , tube filament heat, then boost from the zero , and other tube filament hot, the boost is just boost finished, so this is the same with the bile rectification, 4 470UF The filter is very clean, excellent system will not have the exchange of sound, the filament is DC 12V , the need for two tube filament is in series, the use of DC filament is also to reduce noise.Before the output level automatically switch to promote the headset or push the rear lm1875 , that is, after inserting the headset, the without output, do not insert the headset, is to promote the output. Specification: voltage: the default 18v / current 3A, power 60w or more front output: magnification about 0.8 timesLm1875t output power: typical 20WSpeaker impedance: 4Ω-8ΩTotal Harmonic Distortion:<0.04%Signal to noise ratio: 105dBFrequency response: 14Hz-100kHz Package Includes: 1x Diy Kit Giá sản phẩm trên Tiki đã bao gồm thuế theo luật hiện hành.
