The PCB is designed to have the boost pot mounted
directly. You can use wire if you like - simply
connect the board pads to the corresponding pins
on the pot.
Wiring shown overleaf will disconnect the battery
when you remove the jack plug from the input, and
also when a DC plug is inserted.
Snap the little metal tag off the pot to mount it flush in the box.
You MUST use some kind of heat sink on the legs the transistor
when soldering. They aren’t keen on heat. Any more than 3-4
seconds of iron and its toast.
