What wattage resistors, what voltage capacitors?

[dbishopbliss]

All my previous projects have been tube amplifiers so there may be an obvious answer that I am overlooking.

I do not see ratings for the parts listed in the Kingslayer (and a few other projects I've looked at).  What wattage resistors should be used for pedal projects?  What voltage capacitors?  I'm assuming that most pedals are 9V so they probably don't have to be very large, but I wanted to get an opinion before I start buying.

Thanks for your help.

Well, I'd say double the voltage that components will see. But, don't be fooled, even though the Kingslayer is a 9V pedal, it uses a charge pump so, I'd say the minimum you should use would be 25V rated caps, resistors of 1/4W will be just fine. No need for bigger wattage, cause they are noticeably bigger.

25v is good for the electrolytic (big, round) capacitors. You'll want to look for the film capacitors in the 63v category.

If in a pinch you could use 1/8w resistors on these pedals but 1/4 is the standard unless you want to rock that mojo and pop a 1w in there  

+1 on the 25v or higher on caps. When I first got started I bought an bung hole load of 16v and promptly got into building a string of 18v pedals. Needless to say I didn't make that 16v purchase mistake again.

Jealouse of the tube amp experience.
