New item in high quality. 

Features
  • 6SN7+300B single-ended output form design, high signal to noise ratio, background is very quiet. The preamp gain is high and the sound field positioning is better. The circuit is debug-free and easy to assemble.
  • High-end and brand new components, such as French SCR coupling capacitors, 24K gold-plated diamond ceramics 300B sockets and so on to ensure the perfect performance of the circuit.
Notice:
 
1. This is DIY KIT, you need to solder it by yourself, if you want assembled board please click: LINK.  And because of the instability of some components, we will change to others of the same level, don'w worry. Not including vacuum tubes and transformer, if you want please contact us. 
 
2. Don't turn it on before the output transformer connected to the speaker, no-load will result in damage.
 
3. Input voltage to the terminal connection must be strictly in accordance with the circuit diagram.the other parameters pls according to the PCB. The 5U4 filament  is changed to 5V, and the 2 points that marked "L" are connected to the choke.
 
4. After the module is powered on and works normally, then install the vaccum tubes. Don't touch the tubes during its working.
