can you use wd 40 to lubricate ?


I recently bought a nak ca7 preamp, everyting works fine but i found the volume knob too tight to turn.

Asked a similar question a bit ago under the heading "Source Selector Fix-It Tips" and got some excellent replies. I think it's here http://forum.audiogon.com/cgi-bin/fr.pl?htech&1014251672&read&keyw&zzselector. It did me right.
Radio Shack sells some sort of tuner cleaner that's made for this kind of application. WD40 may contaminate the pot.
