I (didn't) Smell a Rat!

Working on a couple PA issues at the Congregation Beth Jacob Community Center, in the old Methodist Church across from the Old Courthouse here in Plymouth, we had a couple interesting findings

Their Microphone input module blew out and disabled the pulpit mic.   Now their TOA brand amp is a real battleship of reliability.  So I'm guessing a lightning strike; not uncommon in a tall church reaching up into the sky.

And the left speaker died.   HMMMMmmm?   I climbed up and tested it; the speaker was fine and the wiring was tight.   So today, my helper Owen climbed into the catacombs and we pulled thru new cabling, a nice double - jacketed 16-2 heavy pro cable and as we pulled out 45' of old "thermostat" cable (solid-core) we found mouse or other rodent damage.

It isn't common, but then again its not really rare either!    Seen it before and will see it again.

I'll mention that thru the line break, plus the short for the missing insulation that had been eaten away, that TOA amp worked like a champ right thru, on the remaining speaker!


here ya go!
