OK using a bit of 'sideways logic' I see that the 12V 'adaptor' (E-DC-5B

Good afternoon, Brian.

The point of my question was, I want to fabricate a DC power cord for the
VXA-700 with a Powerpole connector on one end, and I need to know if I can
just feed 12 volts into the side of the VXA-700, or does their cigarette
lighter adapter have some kind of voltage reduction or current limiting
circuitry in there?


AFAIK noise suppression and spike removal is all thats in the box, and maybe
a fuse.

For current limiting, use a 2 amp fuse in the supply.

Also note that they sell a lead with no plug on the far end to connect the
radio to a shacks supply.
