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.
Using a single 12V AC input, comes with boost function, low supply voltage to the effect of high-pressure tube.
The capacitance filter of 8 470UFs is very clean.
Excellent power supply system to ensure that the four 470UF capacitor filter clean, tube filament is connected in series, DC 12V power supply, reducing noise.
Using MET series of non-polar capacitor, high-frequency low-resistance electrolytic capacitors, 1% precision metal film resistors, J-class military regulation tube 6J1.
