boomerang power supply

[Paul Sullivan <paulsull@gis.net>]

My Boomerang power supply quit on me recently, and since I've received
no reply from Mike Nelson, I'm wondering if anyone here knows of a
source for an AC adapter that puts out 9 volts AC (not DC), 300-500 ma
(power supply says 500 ma, unit says 300 ma). Ideally with the same size
barrel as the rang, and hopefully reasonably priced. Any help much
appreciated.

Thanks,

Paul
