I guess that was my original question- before I open up the tweeters (which definitely comes with some risk) I was hoping someone could confirm if they D2008-8513 OEM ones did in fact have ferrofluid in them. It would explain my issue if they did, but Ive never seen it mentioned scouring the internet. While 80% of the time Ive been successful changing it out during restorations, I did destroy a KEF 104.2 tweeter one time so I prefer to know if its even neccessary before opening one up. Thanks for all the help.
Interesting about fuse oxidation. Thats one thing I havent checked but will now. Caps definitely good-- I recapped the crossovers when I got them (even the big 68uF shunt to ground electrolytic for the woofer got a film cap). Nice Clarity Caps for the tweeters.
