I had a fascinating conversation with @nielsk this evening in which he regaled me with some history of the 500 format and API consoles. I learned quite a few things I didn't know!
I wanted to share a practical takeaway from the conversation with builders of the Reddish EQ. If you find that the unit produces lots of unwanted distortion (which is not what it should do), you may find that running a wire between the Audio GND and Power GND pins on the edge connector solves this issue. The short version is that this relates to how those ground connections are handled internally within your specific lunchbox/rack, and they are not all the same. There should be no negative effects of making this connection.
@creature.of.habit I am almost certain that this is what we were dealing with when you first plugged in your unit, and why swapping out the rack for a different model cured the issue.
