When you are ordering the electrolytic condensers, you might want to go for 600 Volt ones. These days they are small enough so they don't pose any problems, and they give an extra margin of error. Be careful with the polarity of the condensers. at least one of the originals had the can (negative) isolated from ground because the negative was not to ground. Others here more familiar with this particular circuit can advise you better on this. Don't be afraid to use a 20 MFD for the 16 MFD and a 10 MFD for the 8 MFD, they will just give better voltage filtration.
