I would not invest in anything at the moment. You should ask for another replacemnt amp that is quality control inspected and tested before it is shipped to you. If another replacment hums, then surely there is somethng more devious going on and time to look at other fixes.
He did and they did, now he is looking for other answers.
Hi JohnK, so that means I would have to try yet another AMP? Axiom sent a letter with the replacement saying it had been tested in a enclosure and was working with no problems.
