I spun up a small LED board for my amp and am posting it in case anyone wants to use it. It can be mounted to the 10mmX10mm grid and also the front panel with POT and LED through the panel. The POT should fit through a hole beside the LED if PCB standoffs are used and the headers are mounted on the back of the PCB. I have a footprint for both throughhole and surface mount LEDs ( using light tube for smt ). I used 2 resistors before the POT so a photoresistor can be used too. ( not using it on mine yet but left the footprint in case ) Resistors are 460 and POT is 5k. You can only use 1 resistor if you want, by crossing the 2 resistor footprints with 1 resistor where the white dots show.
I also added an LED output header in case the LED needs to run to the front panel. ( no need to populate the LEDs on the board )
The center of the POT is 15mm from the center of the THT LED, and 20mm from the center of the SMT LED.
I used POTS from tayda: A-597 or mouser: 652-3296W-1-502LF
