Revision
SMD process design, all signal coupling capacitors are imported brand non-polarity, a 1000uf filter capacitor is added to the original 8200uf filter capacitor as the primary filter of the power input terminal, and the original 8200uf is used as the secondary filter. Filtering, so that the design can more effectively filter out the interference caused by the power supply. The input signal line is changed from the original 8P flat line to a shielded line with better anti-interference.
