I left it on over dinner and came back and it read “5 out of 6 tuned”.  Hit Autotune and got 6 out of 6!  Played with pots and auto tune failed. I remember now that autotune will fail if the numbers are unstable. Maybe some deoxit and they’ll be good. But I’m not going there.  It’s playable for now.
