Due to improper encapsulation, heat death will catch up to it eventually. You will probably lose one channel first.
Ampguy conveniently didn't mention that he already had one PA5 replaced, and is one of the lucky few people who got warranty service, and also one of the few who didn't get shipped a defective replacement amp under warranty. Keeps a fan on it to keep it cool, I guess under the belief that a breeze will somehow help with the encapsulation issue. And says "If you have a working one, just use it in a cool env", again missing the issue with encapsulation. On a community level, he trolls people on the PA5 defect thread that their demostratebly broken amp isn't broken and it's all hysteria (that was a low blow, said to another member who was really struggling with the after-sales, despite Ampguy having the same issue.) Even did a word-salad post that blames it on the customer.Maybe I'm just lucky, but enjoying my ~2 year old PA5 original used almost daily.
