Am looking to repair/upgrade the speaker wire terminals on my Jubals from the springloaded push button. Anyone know of a good "minimally invasive" way to do this, or does anyone know where I can get a pair of those buttons, as one of my speakers only has 2 posts at this point. If there are any neat tricks out there that don't involve major surgery on the speakers, I'd like to know about it ... I'd be surprised if this isn't addressed somewhere on this forum, but I can't find it ...
