I'm looking for some replacement knobs for a Keithley 225 current source. I need one of the numbered knobs & a range knob (the knob on the far right). Please see attached picture for the type of knobs. The picture is for reference only.

The range knob will probably be hard to find but I have seen the clear numbered knobs on various vintage test equipment like on some older fluke stuff. The center of the knob can be any color.

Thanks!

After looking around for a week, these are harder to find than I thought. :shock:
