Pete & All,

Another item to consider is the trimmer cap or caps. Thru the years some
metal will have smeared from the metallic section to the ceramic surface.
Remove the offending RF can. The cover has two tabs which can be depressed
in order to remove the cover. The bottom shaft of the trimmer is held in
place with a keeper. Use a small screw driver to push the keeper off of the
shaft. I've used a cotton swab with a few drops of Deoxit to remove the
metal deposits. 

YMMV

Craig,
