Yeah sure. So be sure to check back in and let me know that this methodology worked for you. All these units are old, and will definitely need service or replacement at some point soon. I’ve brought back some pots from the dead that most people would have given up on by repeated sprayings and exercise of the knob (twirling it many times while wet to clean internal wiper contact). I recently brought a 37 year old guitar pot to non scratchy performance that sounded terrible by a few sprays. So good luck
