They are probably worth repair.  A good place to start is Norm's

Subject: [TowerTalk] Rotor questions

I purchased a box with some "radio junk" on a auction for a few $$ some  
time ago. It contained a bunch of CB radios but on the bottom I fount two  
antenna rotors with control boxes.
Today I decided to make the "keep-or-through" test of the units. One  
already had a cable between the box and the rotor which made things easier.
light under the control knob and a humming noise from the rotator was the
 result. Connecting the second unit like the first, 1 -> 1, 2 -> 2 etc gave 
 the same smoke test result.
The rotator is manufactured by CDE (Cornell Dubilier Electronics) according 
 to a label under one of the control boxes. The model number is XL-1 and 
there  are a number of rotators it can be used with such as AR-10-XL,
The rotators have bell shaped bodies and have a "TRA-4" marking underneath. 
Any advice? They had stickers with $100 written on them. Is it worth  
fixing? Where do I start? I remember vaguely reading something, a long time
about a capacitor that can have dried out.
