n Use original TPA3116
n The electrolytic capacitor signal main circuit adopts a patch electrolytic capacitor with a capacity of 4×470UF, which ensures strong and continuous power support.
n High-precision chip resistors are selected for the resistance to ensure a good signal-to-noise ratio of the whole machine.
n PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, full tin spraying process, guaranteed size
Good current passing performance. First-class PCB quality.
n Adopting fully enclosed dustproof potentiometer, the performance is more stable, and it is more durable than ordinary potentiometer!
n Fully shielded high-current inductors are used to ensure a clear and powerful sound.
