[MRCG] PA System Needed

[Craig VonIlten]

I am looking for a vintage LOUD surplus PA system for a riding arena (outdoors).  This would be "ground up" so I need the amp and the speakers.  I'd like some permanent 'horn' style speakers.  I plan to use this with a wireless mic from the back of a horse (consider it cavalry...OK?).  Coleman's Surplus has something with a turntable...not sure it would be loud enough, and I'd need to find old connectors to adapt mic and speakers.  Any and all suggestions appreciated.
