Default What is this thing inside my radio?

I've posted a picture of the underside of my RCA 9X571. My questions is
about that big black tube running diagonally in the picture.

According to the schematics and the SAMS under-chassis view, this is labeled
as capacitor C11 (I think .02mfd, it's not in front of me right now) and
resistor R11, a 10meg 1/2 watt resistor. Upon close inspection but without
tearing any of the black plastic covering, it look like it is a red coil of
stiff wire, with the black plastic tube vacuum-formed around it. I'm
guessing this might be the resistor itself, some kind of wire-wound low
wattage resistor? Why would they have used that? And, it looks like the
capacitor is inside the tube! If that's the case, would there be a
technical reason to put the cap inside a wire-wound resistor? One end of
the resistor goes to chassis ground.

I haven't poked around and traced everything out yet or really examined the
circuit , but has anyone seen anything like this?

Jeff
