Failures might not be catastrophic, but they do happen. A friend of mine's amp recently blew an output tube (newer amp) which took down a few things with it. Didn't start a fire or anything, but he caught it right away and cut the power. If he hadn't been there, no one knows what may have happened.
This gear is not without risk. If you're running chips at 16V, not that big of a deal if something going wrong. If you're running 300V and something goes wrong, there's more that can happen. If a tube failure causes something to short, that can lead to other problems.
I agree that this gear is mostly reliable, but my problem is with those who think they can leave gear on 24/7.
It really isn't safe. These circuits are about the same as they were 60 years ago, and we're using the same tubes.

No one should be afraid of new tube headphone amps. |
