[1230AM]

Quick question - I have a cardboard capacitor in my 47-1230, .05mfd, 600v.  Its yellow and has a black stripe circling one end, but nothing indicating that end to be of any polarity.

Does the single stripe in and of itself indicate the negative end, and hence an electrolytic, or is it merely part of the branding by the makers of the of the capacitor?  Cap says Universal on it, looks like a brand name.  Nothing within the stripe or any other polarity indicator.

Radio still has low volume and this looks like final obvious cap, although I have seven that are very small, bout as big around as a large knitting needle and maybe 3/4 inch long that say 100mf on them - that's it.  I'm guessing those need to be replaced as well?

Thanks
