Yesterday something really weird happened. I was trying to solder a wire to a preamp tube socket lug, and I used a drop of liquid flux, like I usually do. However, it must have dripped down onto the socket itself (where the tube pins connect). When I soldered, much of the solder dripped down into the socket as well, basically ruining that socket pin-connector. I can no longer use it for a tube, and I can't figure out how to suck the solder out of the socket. I think this was caused by my use of liquid flux, and it has me asking myself if I actually should use it. After all, the solder I use has flux in it already. If liquid flux is going to cause the solder to flow unpredictably, maybe I'm better off without it.
