Bill the IC-746 was prone to the same failure mode. Fixed mine before
it happened, high value R, rf choke and a gas gap on the input.
Probably overkill but it's the last line of defense in the radio.

Subject: [RTTY] Followup on ESD from last week
Got the report from the factory on my non working IC-7600. Turns out it was ESD
damage. Three diodes and one IC were destroyed on the tuner control board. Not
covered
by warranty of course, so that learning experience cost me $223.45 plus
shipping of
$85 each way. Ouch.
There never was any lightning, just that kind of precipitation static I've
heard
hundreds of times before, but will never hear again more than a fraction of a
second.
:-)
Take a lesson, boys and girls.
73, Bill W6WRT
