TIDA-00978: I want to confirm that If the pin_1 and pin_2 of D1 has been assembly reversed ?

Hello,

  The diode is not populated on the board. There is a trace connecting pin 1 to pin 15 of the amplifier, pin 2 to a banana jack connector, and pin 3 to ground. But, there is no diode used for the assembly process.

Thank you,
Sima
