So I've been really slow to put my crackatwoa together and noticed, while assembling the Low Current C4S Board, I seem to be missing a 237Ω 1â„8W (red, orange, violet, black, brown) resistor. Do you have any recommendations for locating where would be a good place to pick up this piece? I tried our local Frys but they don't seem to have it. Since I'm a pretty new builder, I'm also somewhat intimated by the vast options available online for resistors. Some appear to be metal film resistors, some are glass, some have different operating temperatures and different Temperature Coefficients.
