Do you have a portable power supply for my Shure wireless receiver?
Shure does not offer a battery supply.
But one can be fabricated from Radio Shack parts. This concept works for Shure wireless receivers with a DC coax jack on the rear panel AND that use 12 volts DC for operation.
Radio Shack has a battery holder that holds 8 AA batteries in series. This provides a 12 volt voltage source.
The output terminal of the battery holder is a snap connector like used on a 9 volt battery. Purchase a mating snap connector and the proper DC coaxial connector to mate with the receiver power jack. The receiver should operate over 6 hours from the 8 AA batteries.
Parts Needed (from Radio Shack):
Battery holder for eight AA batteries - Part #270-407 or 270-387
Battery terminal snap connector - Part #270-325 or 270-324
DC Coaxial Plug - Part #274-1567
Extra wire may be needed to extend the wires coming from the snap connector to DC coaxial plug.
