Look, you little f*ck (and keep in mind that *you* were the first one in this thread to use profanity): let me explain my situation for your little pea-brain to understand.
I am not a professional electronics repairperson. I don't maintain a repair shop, nor solicit repairs. This is why I own no XLR connectors: normally I have absolutely no need for such things. I have no sound equipment, microphones, etc. This one just landed in my lap. I used to be in a band, the leader of which just recently died, and when we tried to use this amp at a gig, it failed. I offered to diagnose it and determine what was wrong with it.
I'm 99.99% sure that the problem is outboard of the jack connections on the amp simply by doing the "touch the input connection and listen for hum" test. The amp responded admirably well to this test, so I'm certain it works. The problem, then, is obviously either the jack on the amp or somewhere in the microphone cable being used. There wasn't enough time to get another cable and test it.
So if you want to continue to berate me for some perceived slight against the propriety of this newsgroup, which after all is supposed to be a source of information for people seeking such, well then, go right ahead and be my guest.
