in Vintage Speakers
If anyone remembers, (or Maybe there’s a post history function on here) I picked up a pair of monitor 10s at a thrift store a couple weeks ago. One tweeter was inoperable, but still functioned on the other speaker. I was told to reCAP and thats what I planned to do. So, today I did my first reCAP job (see pics below) and guess what! The tweeter still doesn’t work. ☹️ I need some help troubleshooting this thing please. I’m just not sure what to look for. 592e9md9j0yz.jpeg

    Did you check continuity across the fuses circuit? Also, it looks like the fuse is seeing all the signal, not just the HP for the tweeter. There should be a common ground, and the positive should split for the high and low pass circuits.

    I did my best to put it back as it came apart. Tested the fuse circuit and there is no continuity between the two sides. Maybe that’s part of the problem?

    Ok, so where do I search from here? Can I take the fuse terminals out and kind of dissect from there? Or?

    I have continuity between both fuse terminals and the crossover board, but no continuity between the terminals themselves. Much confusion...where to go from here?

    Welp, found the problem...fuse terminals were muffed up! Wires coming off were green and fuzzy with corrosion. Bypassed fuse and BOOM. Tweeter is workin. Thanks all for the help!

    That is very common.

    F1NUT has warned about this very scenario.
