I’m pretty much done the board however I have come to the Trimpot on the following filter board. I’ve put the 3 pins in but when I come to the fitting the trimpot it seems so loose am I missing anything? Do I need to apply force to fit the trimpot?? I stuck as when I turn the device upside down it falls off.
That part is the jumper to select 4pole or 2pole modus. If it falls off you can try to bend the legs where it fits on a little bit outward. Just a litlle bit so it will go on easy but won’t fall of.
