02 Place and solder the trimmer
Place the trimmer on the back side of the
PCB and solder it from the front side of
the PCB.
Due to component
shortages we are
occasionally forced to
change the reference of
the trimmer. If you have
received a trimmer with a
footprint that does not
match the footprint on the
PCB, please scan the QR
code to access the
instructions for retrofitting
the trimmer with the
footprint.

contemporary filter. We hope you'll like as much as we are !
