Guitar shops. Looks like Pianos N Stuff carries a 6 foot BNC cable, and I know they have potentiometers because that's all guitar knobs are. Waddell, Brighton, or any other store with electric musical equipment might have what you're looking for.

Hobby shops with electric trains might be an option too.
