In the Eros 2 manual, page 53, second-to-last step, you attach and solder one lead of a 220R carbon film resistor to D7. Then you 'Attach the other lead to 26U'.
I don't see anywhere afterwards that you solder that resistor lead to 26U, so I believe it should read 'Attach and solder the other lead to 26U'.
