40-180 slight hum
#6

Chasing down a tiny hum like that can be maddening. One possible cause also might be bad grounding of some of the decoupling caps through rivets. I would check the grounds on all these connections also, see what they read to chassis. If one reads a few ohms instead of a dead short, you may have found your culprit. Best of luck.
