Hello, I built a pair of GR-research AV-1s and it turned out that one of the tweeters wasn't working. I actually didn't notice it for awhile because I had kind of funny speaker placement and the working tweeter was closer to me. This was the first time I'd tried building speakers, and the first time I'd even soldered. Anyway, I've figured it out now and I've gotten inside the speaker. I measured with a multimeter and started at the wire where the tweeter connects. It didn't register so my tweeter is alright (although I might have messed it up trying to get de-solder, more on that later). Then I worked backward until I got a reading. It turns out that on one lead of a capacitor a get a range of 50-200 mA, and on the other I get nothing. I assume this means that my capacitor is bad. Also, now I guess I have de-solder a little bit and get the capacitor out. How do you de-solder? I just tried heating the solder with a soldering iron, like when I put it together. That clearly didn't work because I didn't have a good way to remove the solder. Is my capacitor bad, and any tips on de-soldering? Thank you in advance for any and all replies.
