Brand: Reland Sun

Maximum Power Per Channel: NO POWER<br> Model Number: 6J1 Preamp<br> Channels: 2 (2.0)<br> Note: DIY kits ! Not finished board. Need you DIY it .<br> Performance parameters:<br> Power supply voltage: Dual AC 18V (the max voltage Canrsquot exceed Dual AC 19V, no less than 18v, otherwise the tube not bright, the sound distortion. If you need to use AC 12v, need to modify the filament buck resistor 2.2 ohm, then output power will be slightly lower)<br> Headphones Amp/Pre-Amp output: magnification about 0.8times<br> LM1875T amplifier output power: typical 20W (Max 30W)<br> Speaker impedance: 4Omega-8Omega<br> Total harmonic distortion: Less than 0.04%<br> SNR: 105dB<br> Frequency response: 14Hz-100kHz<br> <br> Package Contents:<br> 1 x Audio Board<br> <br> Only the above package content, other products are not included.<br> Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.

• X-10D circuit principle design, and optimize reasonable on it, more stable than the machine performance, the tube to increased by 10%.
• 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, 12V power supply the filament, need the two tube filament is in series, the use of filament is also to reduce noise.
• This product uses 6j1 tube for pre-level lm1875 amplifier, with headphones function. the sound more sweet, soft. Better listen than lm3886, tda7294 .
• This machine uses Dual AC 18V input, enjoy yourself in the low power supply.
• Headphones amplifier/ Pre-amp output function: 6j1 tube pre output signal can also drive headphones, but slightly smaller than the digital audio sounds.
