I don't know if I'd consider all these same issues a fluke. I'm sure there are plenty more non issues than issues but that doesn't mean it's a random fluke. There are enough cases of the exact same problem that would constitute it being something more. If a person has to cross fingers hoping that they don't get one with a problem then to me that's more than a fluke. That's a problem. The one guy even went through 3 separate brand new 800 amps and they all had the same issue. But I guess anyone can chalk it up to whatever they feel comfortable chalking it up to. For me, after the 350 cutting out, and then a year later a brand new 800 doing the exact same thing, and multiple people coming forward with the same problem, and consider the people that have the problem but don't speak up. How many does it take to be considered more than a fluke.
Well, I'd actually say that to be more than a fluke it wouldn't be a raw, objective number, it would be a number compared to a population. We'd probably have to look at the population of these amps made, then comsider those that don't pass inspections, then look into those returned for warranty or other service. Subtract those sent in for issues from user error, and compare to the population at large IOT determine potential issues in production, inspection, and design. Even then, we'd have to operationalize how much we're willing to say can be a fluke incident.
Is it enough to happen twenty five times to say that there's a problem in the amps? I mean, maybe if the production is limited to a few hundred or thousand units. Without knowing how many are made and shipped out, we can't say how many instances is "just a fluke". If you make a million of something, no matter how consistently, at least a few of those things will be crap, potentially enough that even a few replacements sent will be crap. On a large enough scale, the unlikely becomes not simply likely, but inevitable.
I'm not saying you're wrong at all, just some food for thought.
Also, JimmyM likes his ampeg, but he does mention when ampeg gear sucks or is sub-par in some way. He's pretty honest about what he has, likes, and uses.
But hey, if you're frustrated enough, there are plenty of other manufacturers making great gear without a similar reputation, and even with my gear and playing situation as it is, I still look at non-ampeg gear all the time.
