Thanks everyone for the input. If the camera explodes or catches fire, I'll post an update . . . with pictures. The last two 650's and the previous 630 that I had were all fine cameras. But, that was some time ago. And since then a number of the more modern SLR's I've used were very quiet. One camera I considered quiet, it would get to the end of the roll and rewind without my knowledge it had done so. That was somewhat aggravating. But, I became accustomed to the near silent and smooth operation. Does anyone know off-hand if the 620/650/630 etc, use a stepper or a normal DC motor?
