 This is a high resolution plan view of the  assembled PCB.
RT1 can be a 100K trimmer, or a 9mm pot, as shown.
However, please note
  • If a pot is used, the PCB cannot be assembled or removed with the pot  in place.
  • The pot should used as secondary to the gain control as it reduces the audio dynamic range.
