Up for sale here is this recap kit for a pair of JBL L100, L100A, L100A Century, or 4311 speakers. This will let you completely recap a set of two (2) of any of those speakers.  This will NOT work for the L100 Century speakers, that kit is here.

These are brand new Supertech MPT (metallized polypropylene film) capacitors, which are super-high-quality and will sound nice and clear. There are two 8 uf capacitors and two 3 uf capacitors. The old caps are pretty bad by this point, but these new film caps will get your speakers singing again! 

These are fairly easy to install as long as you know what you're doing. You will need a decent soldering iron, solder, a Philips screwdriver, wire cutters, and a hot glue gun, rubber cement, and probably some zip-ties or clamps to aid in mounting the caps.

Please note that the new capacitors are much larger than the old ones, because they are so much higher-quality.  They will still fit just fine, since there's plenty of room inside the speaker cabinets.

US shipping and handling is $5, and international is $18. If you have any questions, please ask.
