Description

  • Fever gall preamp circuit board is a principle of imitation crew Musical Fidelity X-10D design, to be rational optimization, performance is more stable than the original machine, tube play to improve ten percent. This machine uses a single 12V AC input by circuit processing provides 6J1 tubes needed positive and negative voltage and filament supply voltage. Power works: a turn on the power tube filament heating is started, when the boost voltage starts from zero boost, and other hot filament tube, and also happens to boost boost finished, so this is the same with bile rectifier, 8 470UF capacitor filter is very clean, good power supply system will not have a hum, the filament is 12V DC power supply requires two filament tube is connected in series with a DC filament also to reduce noise.

    Channel: 2.0 / stereo

    Power input:AC 12V 0.8 A / 5.5 * 2.5 plug

    Weight: 82 g

    Switch function: the power switch/volume

    Size:77 x 75 x 52 mm

    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.

    4, 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 minimal, then continue clockwise rotation is to increase the volume.

    other seller board）

    2: PreAmplifier Board : finished product with tube

    3：PreAmplifier Board + Acrylic shell ： include 1 +2

    Package Included:

    1 x AC 12V 6J1 Valve Pre-amp Tube PreAmplifier Board Headphone Amplifier Buffer case
