Stepper motor controlled balanced inductor antenna tuner - incomplete but good project start. Very good parts and worked last time I worked on it few years ago. Built on a 1/8" panel.
Can't remember the connections to the stepper motors but there should be lots of info on Internet. And you will need to buy or build a stepper motor controller - kits available from several suppliers. There are also two 10 turn pots in the gear box to monitor position of the inductor and tuning cap.
$100 plus shipping. Email for picture.
