Soundcraft SM-20 knob and other large modern Soundcraft mixers

These knobs are common on the larger desk mixers and have come from an SM-20,

They are designed to be used with the Green volume controls with a sort of rectangular top not a D shaft, they all have an extra plastic screw washer so that goes on first to hold the metal panel in then the knobs go on top.

As Soundcraft moved to these pots in all their last big desks they will be common if that shaft is used.

I have just listed these first as they was on an input channel I had to hand

As I can see there are two sizes of the single knob,

Small single knob 14.87mm high 11mm wide

Big single knob 17.55mm high 13.96mm wide

Double knob , top 10.5mm high 9.67mm wide, lower bottom 14mm high 14.26mm wide (these double knobs are sold as a pair top and bottom)

The base is the same on all of these as same pots were used.
