Any Hardware store or big Box store should have lamp kits with everything you need or I mean Gotfingnut needs to repair the lamp.
(from the plug in to the light bulb and all the wiring switch in between)
I bet Utube probably has some instructional repair video's also.
I made several lamp on lathe's. Lamp kits are available and lots of options (styles and colors). You know all lamps kits are made in china. I think Some the threads on the bulb socket are made to the wrong pitch makes the bulbs hard to screw in and out sometimes.
