What is a wire wound pot and where can I get one?

[signalpaths]

I need one of these to build a rig to test output trans formers.  I've heard of wire wound resistors but not pots.  If someone could enlighten me I would appreciate it.

Thanks

Sorry for the very big shot.

Ohmite is one ci I think,  I have an old one here.

Those are great for experiences on power transistors bias too, (and also for a radio controlled vehicles motor speed control  )
