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:

Thanks, RodB and Vlad95,

I was mainly trying to figure out this capacitor to locate a replacement, Vlad thank you for reminding me of the blue capacitor which I almost forgot about being that I couldn't find it on the schematic. I was so busy trying to get the other unsoldered and forgetting the 2 were soldered to the same contacts. Seeing the blue capacitor and some taped wires and missing antenna tells me someone worked on it in the past. I do wonder if they started on it and gave up.

Vlad thank you for the link for restoring the old capacitor, I'm really not concerned about returning to original and wonder if I can just install the 2 capacitors separately. Which brings me to another question in regard to the blue capacitor it's 450V 8MFD, is having a capacitor with more MFD's bad for the radio? If the blue capacitor is ok to use, I can keep it connected and get another for where the green wire is connected from the old capacitor. Hopefully I am testing it correctly, but I have tried testing the old capacitor and not getting any reading.

The more the better. (Within reasonable limits.)
2-5 times more is no problem in this case.
