I wonder if any of you can explain this.
I have had some long XLR mic cables laying around. The cables were made by a name brand---Kopul 3000 series with Neutrik connectors selling at B&H Photo.
Since I have not been using them for a long time, I decided to salvage the cables and connectors to make some short adapter cables.
After my soldering job, I found some pins that were not supposed to be connected had some level of resistance, like 10 to 20 kOhm. So, I tried to look for any bad soldering job. Couldn't find any. Puzzled, desoldered everything, checked on any defect of the connectors, and resoldered. Found the same problem.
After checking everything, I finally found that the PVC jackets of the microphone cable's inner cores became conductive after soldering! I did not apply unreasonably excessive heat extensively when soldering. Yet this happened to the inner core jackets. Is this possible? Have you ever experienced anything like this?
