Key item features

AC 12V input: The DC3.5 / 5.5 x 2.1 socket, 12V AC power adapter, if you use non-plug AC 12V transformer, power cord need to solder on the circuit board. Remember: You can not use a DC power input, otherwise it does not work!
the left-channel input / right channel input: audio signal input, can be connected to mobile phones, computers, M3, the MP4, and other music players.
6J1 Tube Buffer 0.85 times magnification, connected between and before or after class, can effectively filter digital flavor.
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.
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 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.
