Yeah as long as there's not actually any power running to them, they'll generally be ok.

Random side note - one of the best amps I've ever played through was an old Vox AC30 (made in 1970something), that had been totally submerged in a flood a few years ago. The owner left it to dry out for about a month, and it was as good as new.

Even the speakers? That's impressive!
