Is that DIP-SOIC adapter original?
Can you read the numbers off of that adjacent DIP IC?
Are there any SMD parts on the bottom of the board?

You didn't provide the model, but assuming that it's a class D amplifier, the missing IC could be something like an IR2184. If the diode next to the IC is a high-speed rectifier, find which terminals of the IC the diode connects to and see if that corresponds to the correct terminals of a 2184.
