The MC for Elgin's "Miss Hispanidad" pageant wanted a wireless lav. I've got wireless handhelds, but no lav of my own, so I rented one, a really nice UHF diversity unit. Tonight was dress rehearsal. I hooked it up and turned it on and got a few seconds of a really nasty hum before the receiver died. The rental outfit had packed a 14 volt AC wall-wart (plug-power supply) with a receiver designed for 12 volts DC. The moral of the story is always (especially with rental gear) make sure the rating on the wall-wart matches the rating on the gadget it's supposed to power. The brand doesn't tell the whole story: this wall-wart was from the same manufacturer as the receiver, but apparently for a different piece of equipment. The show will go on, but the MC will be using one of my handhelds.
