Sorry to pester you folks with this trivial question, but I am stumped.

I am recapping my radio and the old paper capacitors are not all identified for polarity. They are marked with a black stripe at one end that goes around the capacitor, is this the positive or negative terminal?
Thanks in advance.

Paul,
Banded end is the "negative",(outside foil) end.

Thanks Jim
That does the trick.

And that black band that indicates the "outside foil" is not a polarity indicator. It just indicates the end of the cap that's connected to the out-most wrap of one of the places. Often, it's important to connect a cap such that the outside foil is grounded or at an ac ground to eliminate or reduce such things as feedback.

Polarity on older caps was usually marked with a "+" sign on the positive end. These days, polarity is marked with a "-" sign on the negative end. The caps with the black band are rarely polarized as such and can be connected into the circuit either way without damage to the cap itself.
