I don't but curious as to why you ask

I got one from a flea market the other day, but it has no power supply. I need to know if it requires a negative or positive tip power supply.

99.9% of devices have negative-shell on the DC barrel jacks.

Ok, from my google image searches, they all appear to show a symbol like this:
(-)--(o --(+)

Meaning that it takes a positive tipped power supply.

id guess it was a positive tip/centre. could open it easy enough and see whats going where, one will be to the ground plane of the pcb, and the other will be to some components etc
