I have a pair of Stonehenge II's that I absolutely will never part with, but I am having a problem with one of the crossovers and I'm not sure what the options are. Obviously the chances of finding one for sale are about 0, so this one needs to be repaired. The problem is that one of the large caps on the main board has broken, and because it is so old the ID on it is not visible any more. Also, I am not an expert electronics specialist, but I believe that caps are "polarized", so even if I knew the value of the damaged one and could find a replacement, I wouldn't be sure about the polarization of it to replace it. Any suggestions would be appreciated because I would love to get this speaker operational again without having to do anything crazy to it. Thanks in advance.
