I successfully took apart an Atari 2600 paddle controller, then cleaned and appropriately lubricated the contacts. However, the volume knob does not have the same smoothness as it does on the other paddle controller that I have.
I read online that using a damping grease inside the base of the potentiometer gives it glide and smooth action during rotation of the knob, and I believe that was what was in there when it was new.
A lot of people online recommend Nye damping lubricants but they are in excess of $40 for a 50g tube.
Has anyone found a cheaper alternative? I can't really justify paying forty dollars on damping grease to use on a three dollar controller. Every paddle controller I've used has this issue so it's not like I can go out and replace my set with a guaranteed good pair.
