Hi Red,

Just for general interest, here is a list of capacitor tolerance codes.  Usually, power supply caps have a wide margin for error, unless it's going to be supplying a high frequency device.

Just as a general note, I think the issue that nBit7 is refering to, is that non-polarised caps should not be replaced with polarised caps.  Replacing polarised, with non-polarised would generally be fine.  Non polarised caps are used when the voltage across the cap will have both positive and negative swing.
Good good study, day day up!
