so i own a tube peavey classic 30, and i just came upstairs and realised i had left it on, for a good 5 hours :/. is there any chance it could have done any damage?

it'll wear out the tubes but it should b fine

This. If you do this regularly, then your tubes won't last nearly as long, but no damage to the actual amp.
