An interesting factoid - the 12v rail on the K3 finals is powered even
when you turn the radio off. Thus, a power spike on the mains could get
into the radio.
Best practice is to disconnect everything when not in use.

Hi All:
It looks like we took an EMP hit at home from nearby lightning just last
night. The XYL was up with the baby and said the whole house lit up
sometime after midnight. So far, it appears I've lost a TV, laser printer,
the shack PC, all the outdoor security cameras, and my internet service.
As for radio gear, my Astron VS-35M power supply was showing low voltage
output, but a power recycle corrected that. The Elecraft K3 was actually
powered off and disconnected from the antennas, but it was throwing errors
when I powered it up. I assume that was from the connection to the
computer. I did a soft reset and it seems to have recovered, but I need to
do more thorough testing. The KX3 was only connected to power and was
powered off, and it seems to be OK so far.
The other ham radios seem to be OK, except for an old 1990s-era Radio Shack
scanner that likely can't be replaced. I may crack that one open and see if
there's something obvious that can be repaired.
Any advice for what other checks I should perform on my house and equipment
(especially my K3 and KX3) to check for hidden gremlins before I start
calling the insurance companies and getting the claims process rolling?
