Product Description
DC12V Car 6N8P (6H8C 6SN7) Tube Pre-stage Finished Board
Parameter:

6N8P (6H8C 6SN7) is the best sound. Single tube, horizontal version of the tube front stage. The horizontal mounting of the tube greatly reduces the height of the case. The circuit is simple and the sound is good. High playability
Voltage requirement DC DC12V 1A
Contains a high-voltage booster circuit. The flavor of the tube under high voltage is incomparable with low voltage. 6N8P anode voltage is 250V
PCB specifications: 135MM*92MM
The height of the tube is about 40mm
Contains a 6N8P Shuguang tube
Note: Please fix LM7806 on the radiator before powering on, or use the chassis for heat dissipation. (The second edition uses a 3A high-power voltage regulator chip, no need for a radiator. Improved filtering.)
