Hi Tom,
There's really no reason to use a higher voltage electrolytic capacitor than what the schematic shows unless it gives you a warm fuzzy feeling. Buying 500 volt electrolytic capacitors versus 450 will probably cost 50 per cent more. You'll also find that all the paper capacitors in your set will be in some stage of deterioration and will leak when DC voltage is applied or simply won't do the job when a signal is applied. You might as well order all the caps you'll need for the entire set as well as any resistors that are out of tolerance. It'll save shipping charges. I buy most of my parts from Mouser. Just Radios is also good. If you buy from either you can be sure of the quality. If I have an urgent need for one or two I'll find them on Amazon or ePay with free shipping.
