The problem is that many of these develop a green coating inside the socket assy that becomes resistive (not measurable) over time and humidity.
Back when they were new, we'd order a new socket. When they got harder to find, I'd take them apart. They're usually held together with melted plastic posts. I would drill them out and carefully separate the front and back half.
if there was green (or worse) tracking between the Focus pin and the ground pins (there's a built in arc-gap in there), I would get a Dremel and carefully grind out the contamination like a dentist would remove tooth decay. Clean with IPA and dry well.
If it was repairable, I'd reassemble with a couple of well placed drops of RTV where the plastic posts were drilled out.
