Part Lists

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.

Optional Parts

Here are some parts that you may need, or that are "preference" things: I can't call them required, since some may disagree.
