Description of 🔊 6J1 Valve Preamp Tube Amplifier with 8 470UF Capacitor Filter: Enhanced Sound Quality and Stereo Amplification

✔Connect the 6J1 tube pre-amp between sound source and amplifier, it will effectively filter digital flavor, the music and human voice will be relatively good. ✔Eight 470UF capacitor filter is very clean, excellent power system lead to no hum, filaments are powered with DC 12V and need to be connected in series in order to reduce noise. ✔Coupling capacitor is electrodeless electrolytic capacitor with high frequency and low resistance. ✔Using DC 5.5*2.1 socket and AC 12V transformer, you can also use AC 12V transformer without plug, just need to weld the power cord onto the circuit board. ✔This DIY amplifier kit comes in parts so you can assemble them together by yourself, enjoy the process of building your own tube amplifier.

Useless Filter, Ruined Sound Quality

This product did absolutely nothing for my home theater system besides ruining the sound quality. The only positive is that it was easy to install. However, the negative impact on my electronics made it a complete waste of money. Would not recommend.

Pros
  • Enhances the sound quality of audio systems by filtering out unwanted noise and distortion.
Cons
  • May cause a significant increase in the overall cost of an audio system due to the need for additional equipment and installation.

Higher quality than most other kits I've played with

The board has exceptionally good markings, assembly is almost complete and there was no problem with the documentation being there not included. with this kit. The only problem is that the values of all the large electrolytic capacitors do not match what is actually printed on the board. We'll find out soon if it makes a difference :/

Pros
  • ✔ The coupling capacitor is a high frequency, low resistance electrodeless electrolytic capacitor
Cons
  • Quality
