Built-in substrate temperature detection capability. STK411-210E Pin Configuration
0.1µF film capacitors placed parallel to the large electrolytics to suppress high-frequency noise. 2. Input and Feedback Network
To prevent popping noises and radio-frequency interference (RFI), the input stage must be carefully filtered.

When sourcing a replacement IC, beware of counterfeit "STK" modules, which may be of lower quality and cause poor audio performance or premature failure. Buy from reputable electronic component distributors only.
The standard application circuit for the STK411-210E requires a split (dual) power supply ( ±VCCplus or minus cap V sub cap C cap C end-sub
Note: The functions of all 18 pins can vary. For accurate implementation, always consult the manufacturer's datasheet.
Original STK411-210E chips are becoming scarce. If a direct replacement is needed, here are viable options:
