I had the same problem with my IC756 Pro.
Fixed it with an "N0XAS Universal Keying Adapter 2", which uses an optical 
coupler to give virtually 100% metalic isolation between rig and amp. Been 
in use for several trouble free years now. Google N0XAS Ham Gadgets for 
details. (I have no connection with this company just passing on what worked 
for me!).
Good Luck
