Also, try to match your caps if possible.

BTW, good luck with finding your caps at radio shack too..They really don't stock many different values and types. Your best best would be to order them. Perhaps more than a couple just in case. (they are probably cheap)

For matching, if you have an LCR meter or something, or access to one, try to find two that have the closest match.

Capacitors, like resistors have tolerances, because we live in an imperfect world. So, don't assume the caps will be their stated value. They are only guaranteed to be within so and so percent from the stated value, as per the tolerance rating.
