Well, rats.  My K2, with antenna tuner, got hit by a nearby lightening
strike.  It still works ok, but it's deaf.  Where do I start
looking for the zap?

Sorry, but with that sort of question, the only practical answer is that you
start looking somewhere inside the K2 enclosure.

You will have to define 'deaf' a bit better.  If it works OK, then there is
nothing wrong!!!  We can help best if you are clear and unambiguous in your
descriptions.  If it has weak receive signals, that is another matter, and
you should try the Reciever Signal Tracing outlined in the Troubleshooting
part of the K2 manual.  If the receiver has no output at all (not even
noise) then start tracing in the audio stages and work your way toward the
antenna until you find the dead stage.

Once you isolate to one or 2 stages, we can help you isolate the failing
components.  One consequence of lightning zaps is there may be multiple
failed components, find them one at a time.

73,
Don W3FPR

I would add two things here:

   1. when you open the case up, a careful examination may reveal at
      least some of the discharge path, damaged parts, and so on, but
      you will most likely have to do the signal tracing that Don mentions.

   2. I note that frequently you will find that you are at the beginning
      of your problem; ESD events (of which Lightning is the largest I
      know of) can leave a lot of the semiconductors inside "walking
      wounded", only to die later.  Be ready to have this become an
      iterative process.

Best wishes for a speedy recovery for your K2.

73 de W5SV, Dave

Turn it into your insurance company and buy a new one. Make sure to include
the value of your building time in the price you give them.

He probably already did that, but now he wants to repair the burned up
one to have a second rig :)

If the insurance company paid for it, they'd also physically take it.
