Improved X10-D audio fax 6DJ8 (6N11) version of the tube buffer board 4 tubes, stereo.
A stereo board, single-ended input, single-ended output, can also be customized according to requirements.
The British "X10-D" audio fax is a product launched in the mid-1990s. It has excellent sound effects and a unique appearance. It is also a sensation after being put on the market. Its function and advantages are: connecting it between digital audio sources such as VCD, CD, DVD, optical drive and power amplifier, can greatly reduce the "digital taste" and "transistor sound", so that the entire audio system brings a sweet Natural "guts".
"X10-D" audio fax index: distortion 0.008% (10Hz ~ 100KHz), frequency response: 10Hz ~ 100KHz (± 0.2db), output impedance: 200Ω, no gain, input and output signal 1: 1, use Holland 6922 (6DJ8 ) Electronic tube, the domestic model is 6N11.
Improvement of this line;
1: Use 4 imported 6DJ8 (6N11) electronic tubes, two for one channel to enhance the buffering effect.
2: The power supply adopts a series-type regulated power supply with adjustable power supply, and its dynamic internal resistance is basically unchanged. The technical indicators and effects of AC internal resistance, ripple factor, transient characteristics and so on are much better than the bootstrap circuit used in the original machine.
3: The filament is also changed from the original unregulated power supply to a three-terminal stabilized power supply.
4: Circuit boards, resistors, filter capacitors, coupling capacitors, tube sockets and other components are better than the original components, and the sound quality and effect are better than the original ones.
5: This circuit board considers layout layout in terms of anti-interference, reducing ripple, improving sound quality, etc. One point is grounded, the line is very quiet, and the signal-to-noise ratio is more than 100DB, as if it is not turned on.
This circuit board has an immediate effect on tens of thousands of high-end CD players and decoded sound sources, and is more effective on low-end machines, and is a powerful tool for improving sound quality and timbre.
LG220 finished board is equipped with imported second-hand 6DJ8 electronic tube.
LG220 finished board with domestic 6N11 tube.
LG220 finished board is not equipped with electronic tube.
