In addition to the normal visual inspections that you have probably already done you could check the coils and connections for continuity and if you have a the
equipment a low range resistance check of the different coil winding elements.
One of thing we use to do regarding
electrical damage to transformers and coils with the smell test. Most will have a very distinctive
odor if burned. If it stinks it is probably bad and just a couple of resistance/ resonance test were made prior to tossing in trash or disposal and some larger items do need special disposal due to PCB's.
Mind sharing your boat's set up when struck? I know lots of people report
VHF and
SSB damaged even when disconnected. Were you all powered up? Radios in use? Did you have your ground plane/ ship ground and DC Ground in common or separated and if so how? Was your aboveboard
rigging bonded to Radio/ Ship or DC Ground or isolated? Do you have a
single backstay that was used as the SSB
antenna with two insulators?
Would be nice to have a few reports from those who actually went through what you did to get actual information on best practices for similar set ups/
thanks and good luck with your
replacements and
repairs.
