The Tik was definitely not damaged.  Did the surge suppressors protect it?
I don't know, I guess that's part of my question here.

Never seen a surge suppressor blown I don't think.  Never seen one
charred.  I have had to swap them out in a few cases to fix ethernet
problems.

top and bottom.
Do you have any data on which is best?
