PARTS LIST

This parts list is also available in a spreadsheet format which can be imported directly into Mouser for

easy parts ordering. Mouser doesn't carry all the parts (most notably potentiometers) so the second tab

lists all the non-Mouser parts as well as sources for each.

LED current-limiting resistor. Adjust value to change LED brightness.

Can use 10uF here and leave C6 empty. See build notes.

Can omit and use 10uF for C5. See build notes.

Can use 10uF here and leave C9 empty. See build notes.

Can omit and use 10uF for C8. See build notes.

Reference voltage filter capacitor.

Power supply filter capacitor.

Can substitute BC549C (rotate 180 degrees).

Reverse audio (reverse log or antilog) taper.

Audio (log) taper.
