4. Bopfimer HiFi 6J1 Tube Amplifier Headphones Amplifiers LM1875T Power Amplifier Board 30W Preamp Bile Buffer DIY Kits



  • Before the output level automatically switch to promote the headset or push the rear lm1875 amplifier, that is, after inserting the headset, the amplifier without output, do not insert the headset, is to promote the amplifier output
  • This product uses 6j1 tube to do pre-level lm1875 amplifier, with amp function. After 6j1 tube buffer, can significantly reduce the “digital taste” and “transistor sound”, so that the whole sound system to bring a sweet natural “bile”, the sound is more sweet, soft. Than the average lm3886, tda7294 better listen.
  • The pre-level is the use of 6J1 fever tube gall bladder before the class: imitation machine music fax X-10D circuit principle design, to be reasonable to optimize, more stable than the original machine performance, the tube to increased by 10 percent. This machine uses dual AC 18v input, do not have to worry about looking for high voltage power supply The board comes with boost to enjoy you in the low power supply to enjoy the charm of high-voltage tube
  • Power works: a power supply, tube filament began to heat, then boost from the zero voltage began to boost, and other tube filament hot, the boost is just boost finished, so this is the same with the bile rectification, 4 470UF The capacitor filter is very clean, excellent power supply system will not have the exchange of sound, the filament is 12V power supply, the need for two tube filament is in series, the use of filament is also to reduce noise.
  • The output of the sound slightly smaller than the digital sound source, thrust in general, if the friends can accept this way, but also the output of the product, Then you can try, after this product sound source processing, headset sound there will be a kind of sweet and delicate “bile.” Headphone output function can also be used to do the output level, then the other after the amplifier.
