My first post… It all started about three weeks ago when I hauled two sets of L100s out of the closet after about 20 years. I bought one set new in the mid seventies and the other set used in the mid eighties. I decided to refurbish them and found this site when I was looking for information on the L100s. The grill frames are warped, dinged, and need replacing so I decided to reproduce them with the help of a CNC router. I ended up using MDF for the base and they came out better that the factory originals. My first question is, does anyone have a source for the interior black grill fabric? I have been reading posts for weeks and have noticed suggestions to use fiberglass window screen as a replacement. That sounds like a great idea but was just wondering if anybody has ever found the fabric JBL used. I will offer these reproductions to Heritage members if anyone is interested.
