Are there any obvious things I should look for? Any tips in checking out a used Mark IV would be appreciated. I would expect to replace tubes and such, but other than that...

When I got my mark IV, I had an issue where it would make an incredibly startling pop crackly sound when coming out of standby on simulclass.
It was prefectly quite on class A.
