the an1x has unusual Dshaft knobs in the sense that the arrow points in
the opposite direction of the D shaft so a "common" knob (arrow-same-direction)
will not work, if u try a knob type with fixing on the top then u will be sure it works
like this one :

or else make sure u get knobs with the correct Dshaft orientation
