Peter, is the noise reduction caused by your fingers conductively 
touching the caps, or by downward pressure? If the later, use an 
insulated alignment tool and press down on different areas of the MB. 
Maybe there is a shield that is loose, or a MB to ground screw. Tough to 
find, but see if it is you electrically touching the top of the caps, or 
physical pressure.
