If you would like to keep the receiver in original condition and not have to gut the line filter and the
original input line filter is not damaged, then using an isolation transformer is a good solution to prevent
tripping an outlet that has a GFCI. An isolation transformer provides balanced and isolated power
to the receiver so that  the chassis will not be "hot" or unbalanced in relation to ground even with the
normal leakage in the filter. I have found in many cases using an isolation transformer will greatly
reduce line noise from getting into the receiver also.

Hello list:
I agree that this topic has been adequately addressed (beaten to death) 
but I'm in need of an education re: the alternate; isolation 
transformers.   If getting zapped is the result of a fault within the 
device,  what does an iso transformer do to address that issue? I'm 
assuming that the transformer is installed at the mains, i.e., before 
the plug.
Thanks in advance
Mike
