Product Description

Aoshike 6J1 valve tube amplifier kit 6J1 tube preamp amplifier board Pre-amp Headphone amp Preamplifier Aoshike


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.
1, AC 12V Input:
Need to use AC 12V power adapter. If using a plugless AC 12V transformer, need to solder the connect line to the board. Remember: Can not use the DC power input, otherwise it does not work!
2, L / R channel input:
Audio signal input, can be connected to the phone, computer, M3, MP4, and other music players.
3, L / R channel output:
Audio signal output, can be connected to the audio signal input of amplifier, amplifier board,Provide full music enjoyment to the post-amplifier!
4, the power switch / volume knob:
Turn the knob counterclockwise just start to reduce the volume, when the volume off to the minimum, if you continue to rotate until the "tick" sound, then the power is off, the light goes out; In the closed state, turn the knob clockwise, hear the "click", the indicator light is on, that power is turned on, the volume is the smallest, and then continue to clockwise rotation is to increase the volume.
