Thanks for the replies; I solved the problem on my 630.
I had a rattle, and with the normal checks I couldn't pin down the problem, so I pulled the speaker cone, cleaned everywhere, put some temporary shims around the voice coil and reassembled. That cut the problem in half. Put some temporary nuts and bolts in the speaker to cabinet mounting holes and cut the problem by another quarter. Replaced the #42 tube and the problem went away. I guess when your dealing with three causes its kind of tough to trouble shoot with the quickie checks. Anyway, thanks again, Just wanted to make sure a blown speaker wasn't some mysterious, unsolvable problem like tired cone paper.
