Aaaah, I see. But the Google Docs parts list has R74's part number listed as "660-MF1/4DC1003F", which I believe is the same part number for a 100K Ohm resistors (R8, 12, 13, 14). Is it ok to use that part as R74? I assume not if R74 requires 249 Ohms and the part number is for a 100K Ohm resistor. I guess that's my concern, that the part number listed is that of another value that isn't interchangeable at all.
If we can in fact use this 100K Ohm resistor for R74, that's great. I just want to be sure as I am somewhat inexperienced in this sort of thing. :)
Thanks,
Arturo.....
