6z4 tube rectifier + 6N3-J tube cathode output tube preamp amplifier board
Brand: Electronics BoardJINGLUYAO

Specification:
Tube rectifier can better protect 6N3, let tubes last longer, warmer tone.
Dual 180V high voltage power supply, 6z4 filament with 6.3V AC power supply, 6n3 filament choose to use 7.5-8V rectified AC to DC power supply or communicate directly with the 6.3V power supply, are not noise and current sound.
Double-sided PCB labeling, both positive and negative elements can be installed, the installation is to make the picture tube protruding into the chassis, two kinds of assembly methods as you like.
6.3V filament rectification using 7806 three-terminal regulator, some experts say is the best filament voltage 5.9V 6N3, you can try to compare.
