I have a 20+ year old Velodyne servo subwoofer. A couple of years ago, the volume knob started acting up. The sub only works when the volume knob is in a few spots. I remember this happening a bunch of times with clock radios over the years. Is this something I should fix? If so, who should I bring it to (what kind of technician)? How much should it cost to fix?
Thanks
