Its not necessarily the high volume levels that get ya. A static crash from nearby storms unimpeded by AVC can create quite an audio voltage pulse momentarily and the "kickback" voltage from the audio transformer can soar. I've never had a 630v yellow-cap fail in such an instance but it would be bad form to suggest that as the way to go. If the cap shorts it may take out the output transformer, field coil, etc.
Smart money says overrate the cap. It can't hurt!
