Feature

●6J1 Tube Buffer 0.85x magnification allows you to effectively filter digital flavors when connected between sauces and class
●FE-6J1-2 Heating Tube Preamp Board is an imitation crew musical fax X-10D circuit design with reasonable optimization, more stable performance than machine and 10% increase in tube playback. This board uses a single 12V AC input, circuit processing provides the positive and negative voltage and filament power voltage required for 6J1 tubes
●Powerwork: The filament heating of the open power tube begins and when the boost starts from zero voltage, the boost of the hot filament tube also ends the boost boost, which is the same as Gutz Rectifier, 8*470UF Capacitor Filter is very clean and there is no ham in good power system. Filament is 12V DC power supply. Two filament tubes should be connected in line with DC filament to reduce noise
●AC 12V Input: DC3.5 / 5.5 x 2.1 socket, 12V AC power adapter, non-plug AC 12V transformer, the power cord should be soldered to the circuit board. Note: DC power input cannot be used. Otherwise, it will not work
●Left channel input/right channel input: audio signal input, can connect to mobile phone, computer, M3, MP4 and other music players


Description

ROLE LEFT CHANNEL OUTPUT/RIGHT CHANNEL OUTPUT: Audio signal input amplifier, audio signal output terminal can be connected to power amplifier board.
Power Switch/Volume Knob: Turn the knob counterclockwise to start lowering the volume, lower the volume to the minimum and rotate until you hear a "clicking", the power is off and the light turns on. OFF; When closed, turn the knob clockwise to hear a "click" sound, the light is on, the power is on, the volume is minimum, and the volume is turned clockwise to increase the volume.
