FWIW I think Schubert might mean that if a tube pre-amp malfunctions and outputs DC that it can cause the loss of a tweeter IF you are running a SS amp which can pass DC, or, perhaps, a transformerless tubed amp. But a SS pre-amp can pass DC so it is really a draw. It is highly unlikely to impossible if using a tubed amp with transformers or a SS amp which has built in protection.
Almarg, comments? Schubert, care to explain in detail?
Milpai, tubes in a pre can last anywhere from 2000 to 10000 hours depending on design and expectations. I agree with Yogiboy.
