Can anyone help me figure out a capacitor that has 3 wires coming out of it red and green on one side and a black wire on the other. I seem to only find ones with 2 wires and not sure about the difference. It's a Philco 400V, 4-4 MFD. I will try and include a photo.
Thanks,
Guys

That's a dual 4 MFD, red and green are both 4mfd and black is common negative. You should be able to see them in the power supply circuit of the schematic diagram.

Regarding picture 5 on page 1 of this thread this capacitor is #40 on scematics diagram - 4mF+4mF. Black wire is "-" (grount), red and green "+".
But it look like this capacitor was dead and as parralel was soldered two another, in blu and metal.
My advice - foud two new capacitors 4mF x 400V. It may be very small. And restore old as I present in my message here:
