Amp A observed at the one minute and 3 min mark.
See chart for color comparison.
Added amp B Bc of the incorrect color for amp A.
Should be yellow turning to darker green.
I don’t know wtf is going on. This looks all wrong to me. A is wrong. That’s brown. B is brown. D is positive.
I could be wrong.
