After new bulbs and recap
The volume control is exhibiting odd behavior:
When pressing Down, ~50% of the time the volume increases, as does the Up light. Up is always up. In addition when I change volume either way (by holding) the indicator lights seem to shift the other way a tiny bit, almost like settling back a bit. There 12.4v on the 12 v rail (too high?) but everything on board 3 is tested and fine.
Also, sometimes the vol lights seem to pulse left/right, but that may be due to my LED shop lights.
I am also fascinated by how the volume controls works.
