so I'm almost done with my Crack except for a weird doubled voltage from expected on 2 and 6 (if I'm remembering correctly), and the LED to A8 wasn't lit up, so I reflowed the solder on those joints and tried to jiggle the LED a bit, but then it came off the wire. I have a replacement coming, but as I was checking all my joints I noticed it looked like solder was connecting the RCA center pin on each jack to the screw part that connects to the ground. even though resistance measurements were fine, I tried reflowing solder and removing extra with solder wick and a solder pump, but now it's just even dirtier and I don't know if the center pin is connected to the ground still or not. where can I get replacement jacks that will fit in the chassis?
