Lyle, As I recall, the *other* changes affect both line-in and mic-in. On the N1EU website, I've documented those changes with only C value changes instead of R value changes. I think what some folks are requesting is an updated schematic, showing the new values. But what they may not realize is that 7 SMT capacitors are changed -- or in the alternative, the corresponding SMT resistors require solder re-work and that's in addition to the C9/C13 change and so the total parts change may be in excess of 10. That's a lot of propensity for damage to the board and it really makes sense to just opt for the board swap through Elecraft.
