Specification
Brand : Jolooyo
BulletPoint1 : The standard Beijing 6N11 has neutral sound quality, thick bass, delicate and clear treble, and is relatively balanced. Its direct replacement models are 6922, ECC88 and 6DJ8.
BulletPoint2 : PCB:1.6mm thick double-sided plate, the whole process of tin spraying ensures the good passing performance of large and small current. The design adopts one-point grounding mode and the bottom noise is very low. This board wiring is very simple, very suitable for audio DIY lovers to make and use.
BulletPoint3 : PCB specification: 205MM*120MM.
BulletPoint4 : The electronic tubes are placed horizontally, so it is easier to find a suitable chassis. The height of copper column is not higher than that of 5CM.
BulletPoint5 : This board has its own volume / bass / treble / balance adjustment.

Specifications:
This board is not suitable for the sound of full-frequency loudspeakers.
The board is not suitable for crystal pure post-stage (without potentiometer) with more than 20 times amplification, especially the post-stage power amplifier of DIY, which is generally installed with the same chassis as the later stage power amplifier board and leads to the potentiometer, which may have a greater bottom noise. Before you buy a circuit board for assembly, make sure you know how to adjust the amount of feedback, understand the specifications of grounding and signal shielding, and understand impedance matching.
