"I'm not sure what Turtlehead is talking about - all concentric plugs have a plastic insulator between the inner and outer conductors. "

The OEM has the plastic insulator extending into the opening of the positive conductor. This way if you insert the plug into the headphone jack it will not connect to any part of the headphone jack. The plugs that I have and I have five or six of the same size and maybe 50 of other sizes, have the inner conductor (Positive) extending out to the end of the plug. If you insert this type plug in the headphone jack then you have a good chance of putting 12 VDC into your head phone circuit.
