I have an IC-756 Pro II that has developed a problem on receive. The
receiver intermittently goes dead, the audio completely drops out except on
very strong signals can be heard very weakly. When the audio drops out it does so slowly over a matter of seconds.

It's not a misadjusted issue say like the RF Gain or squelch nor a
coax/antenna problem. Nor any malfunctioning jacks.

Has anyone seen this issue before? Any input would be appreciated.

Look for a relay in the signal path that has likely become funky. 

Tapping on relays while under power with a spudger like the eraser end of the common lead pencil or a chopstick can often cause changes in conductivity that help pinpoint the dirty or pitted relay contact.
