That said, you also have to blame the correct item when the
GFCI trips. The fault is not a "bad" line filter in the 390A.

A "Good" line filter in the 390A is guaranteed to trip a GFCI
that's operational if you've got a good ground.

Again, flawed advice. Don't tell somebody to "fix"
the component that trips the GFCI when the component
is behaving as designed. Yes, the GFCI tripping is
drectly related to the line filter. But here it indicates
that the line filter is working as designed!
