Text and image details
There is no schematic diagram provided for this board, and the color of the PCB in stock is yellow. The frequency division point is 30Hz, and the drumming is booming. Be careful of the horn shaking. The high-frequency division point is 10KHz, which is delicate.
Don't say our board is ineffective, first consider whether the Fo of your subwoofer can reach this point.
This board is not suitable for use with crystal pure rear stage amplifiers with a magnification of more than 20 times (without potentiometers), especially DIY rear stage amplifiers. Generally, there will be some background noise when installed. If installed in the same chassis as the rear stage amplifier board and the potentiometer is led out, the background noise may be even greater. Unless you are a DIY expert who knows how to adjust feedback, understand the rules of grounding and signal shielding, and know impedance matching, it is not recommended to purchase circuit board assembly. Our store does not have time to provide technical support. To achieve lower background noise, you can choose a finished machine.
[Material Description]
The standard Beijing 6N11 has a neutral sound quality, thick bass, delicate and clear treble, making it a well-balanced and good tube. Its direct replacement models are 6922, ECC88, and 6DJ8.
Standard configuration includes one Shuguang 6Z4 rectifier tube
PCB: 1.6mm thick double-sided board, fully processed with tin spraying to ensure good passing performance of both large and small currents. Designed with a single point grounding method and minimal noise floor. This board has very simple wiring and is very suitable for DIY audio enthusiasts to make and use.
The circuit board adopts a one point grounding method for grounding, which has good bottom noise suppression effect and a peak bottom
