Socobeta 6J-I Electron Valve Pre-amp DIY Tube Headphone Amp Stereo Bile Preamplifier Board Buffer Effector DIY Kit

CIRCUIT SCHEMATIC DESIGN：FE-6J1-2 fever tube pre-amp board is the circuit schematic design imitation crew Music fax X-10D, to be rational optimization, more stable performance than the original machine, tube play 10% increase. LOW SUPPLY VOLTAGE：FE-6J1-2 fever tube pre-amp board use a single 12V AC input, comes with boost function, low supply voltage to the effect of high-pressure tube. AC AC12V 0.8A / 5.5*2.5 plug power supply or transformer (DC is not supported). POWER SUPPLY SYSTEM：The excellent power supply system of preamplifier board is to ensure that the four 470UF capacitor filter clean, tube filament is connected in series, DC 12V power supply, reducing noise. UNIQUE DESIGN FOR YOU：The preamplifier board use MET series of non-polar capacitor, high-frequency low-resistance electrolytic capacitors, 1% precision metal film resistors, J-class military regulation tube 6J1. MODEL APPLICABLE：6jl electronic tube bile preamplifier can replace the tube type 6AK5, 5654, 6AU6, etc. And the capacitance filter of 8 470UFs is very clean. The 6jl electronic tube bile preamplifier is very easy to install.
