A couple of questions. Is it running at 70volts or 25 volts or both? When you say many speakers how many is that? The first thing I would do is check the total load the amp had on it. A C100 is 100 watts. I would make sure the total draw is less than that.
It was running on 70. I switched it to 25 just for hahas. Still did it, except it went from doing it constantly to the noise coming and going.
I'm not sure how many speakers are on it, didn't count. I just assumed it was going to be a bad amp, but where it doesn't do it on the bench, now I'm not too sure. Of course it loaded differently on the bench with only one horn instead of the many speakers.
I'm just looking for the most common cause of popping and crackling so I can start there.
