POTENTIOMETER
The DIY500 mkII Minimal Kit includes a specialized, high quality potentiometer (pot) for gain adjustment. Designated “RV1″, it has 3 interior pins carrying the electrical connections, and 4 exterior solder tabs supporting a mechanical brace (standoff). Since this pot is just slightly taller than the front panel 1/4″ connector, we will now install it in a similar manner.
Fig. 39 Solder the pot from the bottom of the PCB, pushing down to hold it flush and steady in place. The solder joints will look like this when complete.
Fig. 40 Carefully trim the leads and solder tabs while holding the PCB outwards, with bottom layer facing away from you.
Fig. 41 This is what it looks like from the other side.
Fig. 42 Successfully trimmed leads.
Fig. 43 Make sure the pot is installed straight, with its standoffs flush against the PCB surface.
Fig. 44 Also make sure it is straight from the side view as well. We want our front panel to mount perfectly perpendicular.
