Question on a Philco 95 capacitor....

[Kamakiri]

Working on this for a friend, he's coming home for Christmas, and I'd like to finish it up for him to have for the holidays

This radio's got a few screwy tube caps that have resistors built into them, Philco part number 3787-A, which is a combined resistor and cap. I was able to easily figure out which terminals represented the resistor, I know the chassis ground is for the cap, but I can't figure out which terminal is the other side of the capacitor.

My capacitor tester shows that there's capacitance on both sides of the resistor terminals, which of course it would, since I can't take the resistor out of circuit in this case. Anyone have experience with these?
