(luxury board) 6H3N Matisse tube preAmplifier Amplifier Board (including transformer)

Introduction:

1. Using  Russian 6H3N tubes

2. The main filter capacitor usingJapanese original Pan asonic gold letter capacitor and Ruby capacitor

3. resistor selection of rings metal resistance , the main circuit employs a precision 1%,The rings of metal film resistors, to ensure that the

Overall good SNR.

4.PCB Using 1.6mm Thick Duplex Plate, 2.0 oz copper thickness , HASL whole process to ensure that the size of the current through the good performance . PCB -class quality .

5.With regular factory transformer , first-class quality !

6. The amplifier board layout is reasonable , beautiful, current sound small

The volume of the finished board : Board length: 123cm , width: 8cm ,height: 7cm

Magnification: about 4 times

It can provide two types of transformers with primary voltage of 110V or 220V ，make order pls pay attention，thanks（The transformer must be connected to the right line. The wrong connection will damage the transformer (the appearance may not be visible). If the transformer is damaged, it will not be reissued. Please pay attention!）
