faint signal at gain step 10

[dan]

i finished building my a12 and when it came time to check everything over, i realized that i have a very faint signal at gain step #10, but is fine everywhere else.

any ideas what to check?

Dan,

I'd check your soldering work around the switch resistors. Might reflow or resolder the ones that look shoddy.

Make sure you've got the right resistor value at R7.
