Part Lists
Required Parts
These are the parts required to fully populate the PPA board.
I don't give part numbers for resistors because resistors are more or
less generic. I recommend 1% metal film types for most of the resistors
on the board. See the schematic and the
Part Selection Guide for recommended resistor values and types.
Some components are marked "Alt.". These are alternatives for the
immediately preceding component.

Optional Parts
Here are some parts that you may need, or that are "preference"
things. The Part Selection Guide will help you to decide which
optional parts you want, and which ones you wish to leave out.
