Description:

The original dark words LM3886 and LM833 are used.
Pre-input capacitor and inter-stage coupling capacitor use top-level SPIRIT capacitor 2.2UF, electrolytic capacitor signal main circuit adopts Taiwan famous brand, main filter capacitor adopts
Gold NOVER Audio Dedicated Capacitance
Capacity 2 × 10000UF, using domestic 8A and above rectifying flat bridge to ensure a steady stream of powerful power support.
The resistor uses a five-ring metal resistor, and the main loop adopts a five-ring metal film resistor with an accuracy of ±1%, which ensures a good signal-to-noise ratio of the whole machine.
The PCB adopts 1.6mm thick double-sided plate, 2.0oz thick copper, and spray tin process to ensure good current performance. First-class PCB quality.
The special design of this board is the use of jumpers between the front and rear stages, so that the volume potentiometer can be placed before the front input can also be placed after the pre-amplification, so that noise, distortion is smaller, better dynamic
