* Capacitors are generic 20% tolerance unless otherwise
* noted. Voltages given are minimum required rating. Parts with
* higher voltage ratings may be substituted. The lead spacing shown
* is the distance between hole centers in the PC board. Parts that
* stand up from the PC board on their leads do not need to accurately
* match the values below. For example, the 100nF ceramic disc
* capacitors have holes .2 inches apart, but parts with leads .1
* inches apart can be used easily. Parts that are meant to mount
* flush to the board, like the electrolytic capacitors, should
* be closer to the desired lead spacing.
