[sdiy] Volume control with LDR´s ?

EMI mixing desks from the 1960s, and various early BBC desks too I
believe.

E.g. EMI REDD:

As I recall, they had a fixed lamp and LDR, and the fader moved a smoked
glass or shutter between the two gradually cutting off the light to the
sensor.  No scratchy contacts to worry about.

Ask Steve Ridley, I'm sure he's met similar beasties.
