Specification:
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 finish,so this is the same with the guts rectification,8*470UF the capacitor filter very clean,good power supply system will not have a hum,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.
Instructions:
6J1 Tube Buffer 0.85 times magnification, connected between the source and before or after class, can effectively filter digital flavor.
1. AC 12V input: The DC3.5 / 5.5 * 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!
2. the left-channel input / right channel input: audio signal input, can be connected to mobile phones, computers, M3, the MP4, and other music players.
3. the left channel output / right channel output: an audio signal output terminal can be connected to the audio signal input amplifier, power amplifier board.
