Most amps won't mind being unloaded, notable exceptions being

those having a transformer at the output (e.g. tube amps).

A well designed amp should survive that as well - certainly

if it's meant for PA where cables and plugs get damaged and

a short circuit is a real possibility.
Some amps are designed to survive almost everything except

a direct lightning strike. I once drove a power drill using

an Amcron DC300A, it worked perfectly and I'm still using

that amp...
