Not completely true. There is a thread on a Z32 Forum, which used the same clock, that found the two resistors on the back with dry solder cracks as well. That's what I was referring to when I initially pulled it apart.
The corner burn on my VFD seemed quite large so I was concerned, but looking back at the pictures posted it is there too. Once my family has left town and I have some time, I will break out the desoldering station and pull it apart. Thanks for the help and clarification.
