For completeness and to close this thread, here is a portion of the 
report on the repair of my KAT500 (now in motion and will be here Fri, 
about 2.5 week turnaround).  Mine is #257, one of the earliest (kit) made.

The invoice shows that I'm getting a KHAT (free) with one hour of shop 
time and a nominal shipping fee billed (plus a second Aux cable so I can 
extend to 6' making the shack more user friendly).

Well done Elecraft!
