2X(Newest 6J1 tube preamp amplifier board Pre- Headphone 6J1 preamp bile4112
2X(100%Brand New and High Quality
Power input: AC 12V 1A 5.5*2.5 PLUG
Channle: 2.0/ stereo
Potentiometer Role: Volume adjustment + Power Switch
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. This board uses a single 12V AC input,the circuit processing provides 6J1 tube needed positive and negative voltage and filament power supply voltage.
Power works: an open power tube filament heating is started,when the boost from the zero-voltage start boosting hot filament tube,etc.,also happens to boost boosting ,so this is the same with the rectification,8*470UF the capacitor filter very clean,good power supply system will not have a ,the filament is 12V DC power supply,need two filament tube is connected in series with a DC filament also in order to reduce the noise.
