Where can I purchase bulk cable like that on the A96F transformer so I can make a longer cable to the camcorder?
The cable used on the A96F is generically called "microphone cable". It consists of two inner conductors, twisted together, and a braided shield surrounding the twisted pair. The inner conductors are typically 20, 22, or 24 gauge.
