Inherited pair L100's, tweeters not working, but after testing using 1.5v battery I believe drivers work. Woofers/mids work fine. L Pad pots very stiff but I got them to move. After reading forum posts, I see labor involved removing L Pad from cabinet (taking off foil decal etc) Are L Pads incl. new capacitors available? Seems that buying old unit on EBay might short sighted, since labor is same.

Also, where to find foam grille inserts? Seems FoamTrends and Sculpted Foam Innovators are RIP Help?
