It depends on the amplifier design.
I had a 6LF6 tube short the moment I turned on one of my Futtermans, and it somehow - we still haven’t figured out how - blew the low frequency driver completely out and caused the voice coil to lock onto the magnet when it tried to return.
Amazingly, no damage to the amp!
That happened once in 40 years and god only knows how many tens of thousands of hours of use.
