Consider the inherent rejection of common mode signals in a differential front end. It
doesn't work so well if the signals are different sizes ( rather obviously ).

I'll use 1% caps here too.

I think I understand John.
If the first stage is a balanced opamp input, its a biq question how "balanced" its function
is as a rf detector, the interference signals are likely way out of the operational range
of that opamp. Thermocouple sounds like a very slow device. Pretty much killing
anything even remotely RF should work pretty well.

A ferrite bead won't do that.
