In any case its academic. In either case its enough to fry a Nikon

It isn't. Nikon DSLR's, D7000 included, use a 250V OC transistor for flash trigger. Most DSLR's use a separate high voltage trigger output.

All this business about flashguns frying cameras is the result of a few cameras (most notable being the Canon digital rebels) which used the output direct from an LSI IC to drive the trigger and hence save money on the output transistor. This was fine with modern flashes, but effectively being rated for just 5V, many old flashguns would literally fry the whole camera.
