I am trying my very first electronics project -- building a small and supposedly simple "crackerbox guitar amp" from a schematic and plans I found online. The schematic calls for a 0.047uF capacitor, but the guy at RadioShack said he thought that was a misprint and gave me a 0.0047uF capacitor instead. Will this work, or am I am going to melt something? Thanks in advance for advice, folks.
