Required Parts
These are the parts required to fully populate the MINT board. It's
not necessary to fully populate the board to get a working amplifier. See
the part selection guide for information
on these simpler configurations.
I don't give resistor part numbers because resistors are more or
less generic. You should use 1% or better metal film types, but you
can pick any brand and source that you like that will fit. The hole
spacing is 300 mils so large exotic resistors won't fit. See the schematic and the following text for
recommended resistor values.
Some components are marked "Alt.". These are alternatives for the
immediately preceding component.
