Once again I have a question. I carefully change capacitors in my old jukeboxes and with some help from ARF have been very successful. This time it is a radio phonograph by Admiral 5Y22A. I have a capacitor, shown in the link below. I am not very familiar with these type of capacitors. After reading about small dots that indicate which lead is positive and, of course, the + mark and the line or slash this capacitor has none of those. Both leads are the same length as well.

Capacitor is 0.01 @ 630 V. The markings, in case they do not show well enough in the picture link, are: MF - 630V - .01K.

What the heck am I missing? Non-polarized capacitor? I thank everyone for their help! A great resource for me!

I would not buy common parts on EBay. Known good sources with competitive prices:
Mouser
Sal
JustRadios

For the OP: picture link does not work

Link works, it's a mylar film cap, and non-polarized, so no matter to polarity.

To answer your question, juke, that cap has no polarity. It is "happy" AC or DC.

Working on a kit with several of these, ceramic disc and electrolytic capacitors. The electrolytics are the only ones with any polarity precautions and markings.
