This product uses 6j1 tube for pre-level lm1875 amplifier, with headphones function. the sound more sweet, soft. Better listen than lm3886, tda7294 .

music fax X-10D circuit principle design, and optimize reasonable on it, more stable than the original machine performance, the tube to play increased by 10%.

This machine uses Dual AC 18V input, enjoy yourself in the low power supply.

Power Working principle: turn on power supply, tube filament begin heat, then boost from the zero voltage begin to boost, when tube filament hot, the boost is just boost finished, so this is the same with the bile rectification, 4pcs 470UF capacitor filter is very clean, excellent power supply system wonrsquot noise, DC 12V power supply the filament, need the two tube filament is in series, the use of DC filament is also to reduce noise.

Headphones amplifier/ Pre-amp output function: 6j1 tube pre output signal can also drive headphones, but slightly smaller than the digital audio sounds.
