Box-O-Trix - Parts list
Here is a complete BOM for the Box-O-Trix PCB. If you are having trouble with a particular
part, please just ask
)Most resistors are spec'ed as 1% 50ppm/C, although this kind of precision is not necessary
everywhere - use your common sense if you want to use 5% resistors in some places.
