What Jay said.....if it runs cool and all voltages are within 20% of spec I wouldn't worry about it. You might try pulling the bolts, cleaning them up or sourcing new ones, and then slowly re-torquing them to seem if you can pull the laminations closed if it really bothers you. It isn't hurting anything though if the bolts are tight.
Again, if it is built with rivets then redo all the riveted ground points with screws and lock washers that will bite into the chassis to provide good grounds. Don't mess with their grounding scheme until you have it running with no hum. Then if you want to modify it to a more modern star gounding you can try it. Sometimes it improves old amps, and sometimes they hum!
