Fader anatomy, DUNCAN electronics Slideline 200-560
Luckily this fader will snap back together with ease. I need to mock up some sort of rail to support the slider as there is only one right now.
When that is complete the unit will only require one more. Electrical resistance on this is around 11k [10.8] audio taper.
Mounting is by the center holes only, 4 inches apart. Inside the shell along the left hand side you can see the white plastic rail I need to duplicate.
I think that part was cannibalized, since the unit was missing an entire fader, some knobs and this fader was broken open [without much indication of impact].


Measuring from the outside points of the slider, throw looks to be a hair over 3 1/4".

Measuring from center to center comes closer to 2 3/4" which is a documented size of the present line of Duncan controls, which unfortunately do not include the cast metal shell of the 200-560.
