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 AC power supply,need two filament tube is connected in series with a DC filament also in order to reduce the noise.
