It's almost a guarantee that he'll bring something new, never seen before, and forget whatever amp it was that he was supposed to deliver to the person who's been waiting for longer than most would deem reasonable.
I'd imagine that most LEO's would look at that and have no idea what they were looking at and probably not even want to get into it. And all of it is certainly no worse in my book than the Hog riders who have standard FM radios and speakers on their bikes.
If it were me I'd be requesting two new amps, ont this repair/upgrade nonsense that will have you without amps for yet another undetermined length of time.
