FE-6J1-2 tube -amp board is the circuit schematic design imitation crew Music fax X-10D,to be 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 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 boosting hot filament tube,etc.,also happens to boost boosting finish,so this is the same with the rectification,8*470UF the capacitor filter 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.
6J1 Tube Buffer 0.85 magnification, connected between and or after class, can effectively filter digital flavor.
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. : 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, , the MP4, and other music players. the left channel output / right channel output: an audio signal output terminal can be connected to the audio signal input amplifier, power amplifier board.
the power switch / volume knob: turn the knob counter-clockwise to decrease the volume beginning, when the volume down to the minimum, if it continues to rotate until the "ticking" sound, then the power off, the light goes off; in the closed state, Turn the knob clockwise to hear "tick" sound, light is on, the power is turned on, then the volume is , then continue clockwise rotation is to increase the volume.
